15S39 LCM Bypass Recall - Documented

[Logizyme]

Hey I know a few guys here were asking for any/all details regarding the most recent flavor of the LCM recall - 15S39. For those of you who don't know I am a tech at a Ford dealer.

I had a beautiful blue Marauder roll in today for the recall to be done and I thought I would take the opportunity to document the process and explain a little as I go.

Please just use this information for your own knowledge and try not to take it out on your dealership's employees'. This recall does not pay your technician enough time to do this job and I can tell you not many techs want to get under your dash and cut up your wiring. Your advisors and techs are just trying to do their job and you being a Nazi to either is not something that will help your situation.

So background; the previous recall 14N01 was a customer satisfaction warranty extension. This type of recall is issued when there are widespread failures of a certain part after the factory warranty has ended. Ford is extending the warranty on the specific part only to keep customers happy, these types of recalls are usually not safety related. Ford will pay to repair your vehicle ONLY IF IT HAS FAILED. If your vehicle was serviced under the 14N01 and you had your LCM replaced under the warranty extension your vehicle will not be eligible for the new 15S39 which now replaces the 14N01 which is no longer active. If this is the case consider yourself lucky, most of the LCMs used in the 14N01 had much higher quality relays and should last the remainder of the vehicles life.

The new recall 15S39 is a safety recall. This type of recall is a result of crashes or other safety related issues that have been documented as a result of the failed part - in this case if your headlights were to fail it would increase your chances of getting in a collision when driving at night. This type of recall, a repair is performed to every vehicle to either correct or prevent the failure, and is performed on every vehicle. Ford found it too costly to replace every LCM in every 03-05 Panther, so they developed this bypass kit to reduce parts costs, even though it more that doubles labor costs associated with installation.

Anyway, lets get started.
Open up my box and here is what's inside the 3W7Z-13C788-A LCM bypass module kit:
http://www.supermotors.net/getfile/1116632/fullsize/20170727_101857.jpg
The kit comes with a non-serviceable relay "module" with two harness' covered in convolute and with non-insulated butt connectors already installed and includes heat shrink tubing and zip ties. Pretty typical for this sort of repair from Ford.
http://www.supermotors.net/getfile/1116633/fullsize/20170727_102437.jpg


The kit's harness have identical colored circuits on both sides, with the exception that one side has only 5 wires and the other 6. The relay module is to be spliced in-line to the connectors going to the LCM, with the 6 circuit side being sliced on the harness side, and the 5 circuit side being spliced towards the connectors of the LCM. The colors match the circuits they are to be spliced too so this should be pretty easy to not screw up.
To start I have removed the covers under the steering column, the charcoal colored panel directly under the column does not need to be removed, I just did for clarity. I removed the LCM from the vehicle for maximum access - as most of you know that does not require the pedal assembly to be removed, even if that is what the book says.

http://www.supermotors.net/getfile/1116635/fullsize/20170727_103202.jpg


The 6 circuits needed span all three LCM connectors, the black connector has 4 of the circuits and the two grey connectors each have one circuit each to be spliced.
So all three of the pigtails need to be accessed, and I needed to cut open the electrical tap that protects them, up to the main harness, so I can access individual wires to be cut and spliced into the relay kit. Using the proper tool can prevent damage to the wires that a box cutter or scissors could do.

http://www.supermotors.net/getfile/1116638/fullsize/20170727_104212.jpg


Each of the circuits to be modified need to have their individual wires isolated and cut, and yes by this point the battery is disconnected and your precious radio presets and clock have been reset - deal with it.

http://www.supermotors.net/getfile/1116643/fullsize/20170727_110916.jpg
Now that the wires have been cut, both sides of the wires need to be stripped in preparation to be attached to the butt connectors.

An experienced tech always remembers to double check and make sure heat shrink is on the wire prior to crimping or soldering. I decided to crimp and heatshrink all the harness side splices first, and do the connector side splices second.

http://www.supermotors.net/getfile/1116645/fullsize/20170727_113808.jpg

Next plug the module in and connect the battery for a quick functions test. Everything works properly!
http://www.supermotors.net/getfile/1116646/fullsize/20170727_114839.jpg


The directions indicate to tuck the module up by the PCM and route the harness' below the steering shaft along the instrument panel frame and back up to where they are spliced. The module and harness' are retained with the zip ties provided in the kit.
http://www.supermotors.net/getfile/1116647/fullsize/20170727_120018.jpg
Install the LCM and install the covers and boom were done.


All in all not a fun job. For those of you who have spent some time working under a dash it is not too comfortable, not to mention the lack of motion I have when trying to do detailed steps like cutting and stripping and crimping. Luckily this clean rig was free of dust and debris, most rigs this old are dustier that your attic under the dash.


Overall I think this is a very poor repair, and my recommendation to everyone with a vehicle affected by this recall is to request it not to be performed. If your LCM fails we all know how to fix it, when know who to call and most of us can get the sucker in and out ourselves. As far as I can tell this recall has no expiration and you'll need to let your dealer know at every visit your request the repair not be performed. This repair is probably going to cause a lot more issues down the road as poor splices come apart or a harness chafes or a relay internal to the "module" fails.

Thanks for the post! Great writeup!

Why a non-serviceable relay?

I always thought the first rule when working with car electrics - NO crimp connections, always solder connections.

I'm glad I don't have to get this done to my Marauder.

[Svashtar]

Thanks very much for the write up and the information. I have never received any recall notices on this from Ford.

All I know is that my original LCM, along with the radio, failed very early on in 2005-06 and was replaced under warranty. I assumed it was replaced with the very same type, but maybe I got lucky and got the LCM from the 14N01 by some miracle. (The radio died the second time 20k miles ago). Again, I didn't hear about a new module before or now.

If it does fail again I'll follow up here and replace it myself. I have a bunch of other wiring under there for the alarm, underbody lighting, etc., and I just as soon it not be disturbed.

Thanks again for all the detail.

What a hack.I work for a company that used to be a supplier to Ford in the mid-1990s. I had occasion to work with the Ford reliability engineers and I can tell you that there's absolutely no way they would have let something that could potentially cause the headlights to fail get past the design stage if it were shown to them. This has to be something that the service organization cooked up on their own.

The LCM that they were replacing in the 14N01 recall was exactly the same as the original LCM. That means it will fail over time. Per the recall you only get one free replacement LCM.

This new fix / hack is because Ford can't get enough LCMs and they are expensive.

OK, but the OP did say: "most of the LCMs used in the 14N01 had much higher quality relays and should last the remainder of the vehicles life." (?)

As mentioned, I didn't get a recall notice, but maybe that's because they know they changed mine under warranty? I just hope that if the above is true I got one of the better quality relay ones mentioned, but somehow I doubt it. :-)

Either way, if it fails again I'm not going to go thru this wiring abomination, and will just buy a new one and replace it myself.

The very first LCM's I swapped out under 14N01 appeared the same, with Taiwan? relays. After they got past the initial backorder the LCM's for 14N01 were using Japanese relays IIRC - and that's a relay I would trust more than the original third world ones.



What a hack.
I hope you are referring to the repair and not me - I'm just doing my job and for the time Ford pays me I did a good job here.




Why a non-serviceable relay?

I always thought the first rule when working with car electrics - NO crimp connections, always solder connections.
Cost, cost, cost. Serviceable relay certainly means 0.05 more per unit x 1,500,000 cars, well that's quite a few dollars there.


There are other considerations, such as having to solder upside down underneath a dash panel with the potential for solder to fall and burn the carpet, additional labor time, supply costs. In Ford land, generally, critical engine circuits will be repaired with solder/heatshrink and less-critical body repairs get crimp/heatshrink. Ford has run into some issues from soldered repairs where the solder will soak into the wire insulation a little ways and make the wire ridged, this results in future failures because the wire that was designed to be flexible is hard and breaks or chafes.

[ByronRACE]

Seriously gross. Ford should be embarrassed. How about desolder the relays on the module and replace. Any electronics repair shop can do such a thing. The relays are available through Allied.

I'm speaking to the proposed repair...not your workmanship.

Now we have dead relays in a module doing nothing, a couple pounds of box and wiring and relays that are redundant and unnecessary and clogging up an already crowded area, and a bunch of crimp connectors. Ick.

I prefer this method. https://www.youtube.com/watch?v=fYvZg0q7Seo

It can be done much faster if you spring for a decent soldering station and one of these. https://www.digikey.com/product-detail/en/17535/243-1182-ND/1992576?WT.mc_id=IQ_7595_G_pla 1992576&wt.srch=1&wt.medium=cpc&WT.srch=1&gclid=Cj0KCQjwwevLBRCGARIsAKnA JvcprJohSw5Z6V3mJDqjBYZiNJT34A _mmIaMHAvQjlYfCgOxBSddBhEaArQR EALw_wcB

Or send it to me for a nominal fee. I replace the headlight relay with a 40amp external relay and also replace the three other relays with higher amperage units. I also cover my repairs with a "life of the car" guaranty on my work.

Why spend money on tools you may use only once.

[fastblackmerc]

Even the Japanese relays are no higher amperage than the original relays. That's the problem, using relays that can not stand up to the high amperage, resulting in damaged contacts.

[Dragcity]

Mine will be on the way to you very soon. Went out on me again Wednesday night. Kicked a few times and, poof, back on. That will only work so long...

[BLACKMARAUDER04]

Can someone post a picture where to find the LCM?
I'm on my third one. I want to find one in the junk yard but don't know what I'm looking for.

[fastblackmerc]

Correct... and you know it will fail for good when you need it the most.

[Dragcity]

It lives just above the OBDII port. Steel braket above it. Two 7 MM screws, Just need a nut driver, no rachet required. Three connectors in back Two grey ones come out easy. Then wiggle, force the thing out by pushing toward the fire wall and outward toward the driver side. Its in there..... Then you can dnagle it down to get the black plug from the white connector. That one is a pain. Has a little push tab in the middel that needs to be depressed. Gotta pull pretty hard to dislodge, while depressing the release tab.

JUST pulled mine out.

You will have a 50-50 chance of getting one that works.

The LCM is about the size of a brick.
Located just to the right of the steering column by the OBDII connector.
There are 3 electrical connectors and two 7mm screws.

I'll pay $20.00 each for LCMs.

So, if it fails, do you recommend replacing it, or rebuilding it with your suggested upgrades?

IIRC, after the underbody lighting kit was installed I started getting a "bzzzz" sound when the interior lights dimmed and went out, after getting in and out of the car.

That tells me a relay is opening and closing rapidly, but don't know if that has anything to do with the LCM.

[N40GL]

Sticky, please.

Perhaps also post a picture of the LCM, so we know what we are looking for (amongst a forest of black boxes).

It's real obvious. When I tucked the extra cable away for my ScanGauge to the side of the ODB port you could look up and see it.

Lot's of boxes yes, but this is large and right there, so you won't easily confuse it with anything else.

Mark, it's really pretty obvious...it's right above the DLC (Data Link Connector), more commonly known as the OBD port. Looks like a black plastic brick. Run the adjustable pedals all the way down and you can manoeuvre it out.

[RF Overlord]

I'm on my third one. I want to find one in the junk yard but don't know what I'm looking for.Good luck with that. You're taking a chance that the one from the yard is not just as bad as the one you have. Better to send yours to FBM or replace the relays yourself if you have circuit board repair experience.

[Marauderjack]

I had mine replaced under warranty in 2005....turn signals went out!!:argue:

That "warranty replacement" was later sent to "fastblackmerc" after he sent me one he had already repaired....still works PERFECTLY!!:beer::bows:

Just got a "Recall Letter" from Ford to replace the one they replaced in 2005 but........at 263,000 miles I think they might just laugh!!;)

Thanks again Jim!!:up::up:

Thanks, Bob. Jim sent me a picture (or a link to an EBay picture). At least now I know that all the connectors are on the end of the "mystery box" and about what it looks like. That's what I needed to help my visualization before I dive in there tomorrow and retrieve it.

[BAD MERC]

That's an interesting fix and a very detailed post. I fixed mine before it failed. I used a Ford relay (slightly smaller than a Bosch) and it fit within the LCM where it can be closed and appear untouched. I don't want prying fingers on mine anyway due to the doors/trunk/horn/domelight connections made for the security system at the LCM. Seems like more work than installing a whole NEW revised LCM.

[Svashtar]

I didn't think that of course mine has also been modified with all that stuff for the alarm. I'm pretty much boned if it ever fails.

What was it I heard on TV before I walked into the showroom in 2004? Oh yeah, I remember: "Ford, Quality is Job 1!" [emoji6]

In fairness though, of the 14 times I've taken it back to the dealer, none of the repairs have been for anything related to the drivetrain, always peripheral items. Like LCM, door switches, radios, plastic trim, door panels, fuel gauge, axles, center console, pedals, glove box, etc., etc.

It can be unplugged without tampering with aftermarket connections. Next time your Merc has some downtime send the LCM to me and I'll do the repair and ship it back for the price of postage.

[Svashtar]

Damn, thank you! That's really decent of you, but I'll at least add in for a case of beer for your trouble. I'll shoot you a PM and work out a time that works before too long. I figure it's probably overdue at 12 years now.

Thanks again! [emoji1531]

I could use some help on this subject. I apologize, I have a 2003 Grand Marquis LS. For 3 years I struggled with the headlights not working. I received the notice but my VIN was not on the list and they wanted $800 to replace the module. 2 years ago I replaced the relay for the headlights and all working again. I received another recall letter this time it was for my VIN. I have also been struggling with rear tail lights needing me to tap the LCM to work. My overhead lights occasional worked.
When I got the letter from Ford I thought they where going to replace the module. When the job was done they told me they did a bypass. All of my other issues where still present. I had to tap the LCM to get the rear lights to work.
2 weeks later I loss my blinkers, instrument dash lighting, The one light that comes on when the door opens stopped working. My panic button that would make the horn go in panic mode stopped. The horm that would beep when I would lock the door with the key fob stopped making the beep at lock. It might easier to say the only lights that work are the headlights (which was not a problem since I replaced the relay) and my break lights.This Wed I am having the Ford dealer confirm everything they did is still good. If they say it is good we talked about places that will repair the LCM. I want to confirm what they did is not faulty work explainng all these new problems like my blinkers stopped working, instrument dashboard lights (no longer light up or allow diming with control) and the fact that tapping the LCM no longer allows the rear lights to come on could be due to an issue with their worked performed. I'm in worse shaped since the bypass.
If they say their work is good, should I be able to remove the LCM like I did a few years back or will the LCM bypass for the headlights be an issue for me to remove the LCM and do the relay replacments?
Whats your thoughts on faulty work causing the new problems.
The new problems happened within 2 weeks of their work.

Thank you for any info and I apologize for the 2003 Grand Marquis. This This forum was the closet article on the bypass I could fine. I would be happy to speak with anyone offline if it would be more helpful.

[fastblackmerc]

If this was may car, this is what I'd do.

Remove the bypass and reconnect all the wires that were cut using solder and heat shrink tubing.

Replace all the relay in the LCM with higher amperage units and replace the headlight relay with a 30 - 40amp unit.

BTW... I fix LCMs, it's not cheap but it's not an abortion like this bypass.

[RF Overlord]

Unless the dealer tech did a massively craptacular job, I would expect any problems due to the bypass would have shown up immediately. My understanding is that this bypass is just for the headlights, so shouldn't have had any effect on your other issues therefore I suspect your LCM may have simply given up the ghost.

I can't see any reason why you shouldn't be able to remove the LCM as normal to either replace it entirely or replace the relays.

Sounds like you're the first one here to have issues after the recall, so please let us know how you make out.

*EDIT* Make sure all 3 connectors are plugged in firmly and none of the pins have been dislodged.

[N40GL]

I pulled out the LCM on Saturday morning and it's off to fastblackmerc for repair.

When I dropped the vanity panel under the steering column to get access to the LCM, I found this plastic part sliding around on it. Anyone know what it is, so I can put it back where it belongs?

[fastblackmerc]

Look like the clip from the PCM, sliver box near the emergency brake assembly.

[PyrBliss]

BTW... I fix LCMs, it's not cheap but it's not an abortion like this bypass.


I have a 03' GM with a failing LCM. It's the winter car so need reliable headlights. PM me if your still fixing LCMs. Have no Hi/Lo beams unless I smack the dash hard.

[N40GL]

Look like the clip from the PCM, sliver box near the emergency brake assembly.

That's what I thought, too, because its about the same width. I just can't figure out where it goes, or whether it is essential to put back.

[fastblackmerc]

Mine comes off too. As far as i can see, it really doesn't do anything.

What is the Ford allocated time for the task?

[Logizyme]

What is the Ford allocated time for the task?

1.3 Hours

Well, this thread scares me. I was at the dealers with my car to get the mod when I read it. Talked to another patron getting the same thing done and he said the service manager said 1/2 day. Since I am retired I told the service manager he could keep the car 2 days. :)

Can't wait to get mine back. SO I don't have to keep kicking mine or rapping on it with a screwdriver handle. I picked a good week to send it off. Supposed to rain for days here. Thanks Fastblack 0--=--0

Hokey smoke! Are you certain you want to crawl under the dash to unsplice all those wires?

Are you the original owner? If not the LCM may have been replaced under a previous recall.

Or Ford may have no record that you own the car.

[Svashtar]

I think you hit on something; although I am the original owner, the LCM failed early on, along with the radio around 2005 and both were replaced back then. I would think tho that LCM would the same as the first so would have been part of the other recall, but maybe they installed a newer one.

I'm not going to worry about it, just glad I'm on the site here and learned about this kludgy workaround so I can avoid it.

Unfortunately Ford replaced the LCM (when they could get them) with one that had zero improvements, so it's a matter of time until that one fails.

Just an FYI... Ford will only do one replacement / fix of the LCM on their dime.

Due to another failed work item I decided to see if the mod was actually done. It was easy to tell. :(

Sent mine out on Monday, got it back on Saturday, installed on Sunday. Everything works as it should, tucks up nicely, never to be disturbed again.

The car runs better, looks better and gets better fuel economy too!

A friend of mine went to the dealer for he recall and the car came back with more issue. The parking light will stay on for a whooping 5 min before going all dark. The head light are always on tho but nothing else :( I have not done the recall on my 04 and will most likely wont after seeing how its been done.

I find it amazing that Ford would come up with a recall with this much hackery instead of just desoldering/soldering on new relays. Is that really that much harder? Why do they think a talented auto tech can't desolder/solder parts on a PCA but *can* pull off this wiring mess?

[parker]

That’s why I’m sending mine to fastblackmerc tomorrow. I will have nothing to do with that ****ery Ford calls a repair.

Canadian Marauders have DRL's that keep just the headlights on all the time.

[Dragcity]

Mine works perfect Since repaired, PROPERLY. The only thing that I need to get used to is, the new one is a wee bit louder and crisper sounding than the OEM. I'm sure after 13 years and 110,000 miles, I'll get used to it........

[fastblackmerc]

I still repair them.......

[hotford]

I just my recall done, I personally know the tech working on it and didn't leave the car side during the operation...lol, no issues works fine.......I guess it depends on how good the tech is, the tech who did mine has done over 20 so far and made it look easy...

[Marauderjack]

Jim's repair is the only way to go...4 years on mine and NOT A SINGLE HICCUP!!:beer::bows:

[Donald]

Well, I think the official fix queered a deal on my car.

Shortly after the fix I had to replace a fuse. Not sure what I did to make it blow.

While test driving the car today the potential buyer had the passenger door open and toggled the door lock/unlock. After that the AC was dead, the clock was off and the dome and under dash lights were dead.

Replaced the fuse and all was fine.

I am tempted to remove the fix to see if it fixes the problem. I just can’t contort to work under the dash.

Yes, others years will work but you will experience the same problem if it's not already happening with the "replacement" LCM.

Not me. I did my apprenticeship with Fleet Service at the Post Garage for the RCMP. None of the CVs had DRLs enabled, kinda hinders sneaking around. A dead give away that a vehicle was an unmarked one, was if no DRLs were on. Believe me, they stood out in a sea of headlights during the day.;)

I doubt Ford built any Canadian VIN'd cars without DRL just for LEO's. Disabling the Canadian DRL in a panther is as easy as removing a fuse, which is likely what happened during initial outfitting.

Newer Panthers have the kill-DRL via computer I've been told, the older ones it was a simple module to unplug.

Recently I got a nasty letter from Ford because I did not have the LCM recall done, threatening me for being negligent if the lights fail. The service department at my reputable local dealer advised against having this repair done unless I had any prior problems. Your explanation of the procedures involved clearly demonstrates that a half-ass fix to something that is not broken can be worse than leaving it alone. Thank you for this post, and I express my disappointment with Ford. :nono:

Do the new modules (4W7Z-13C788-BD) that Ford sells have the update included or do they still need the fix/repair?

No, there is no update other than new or improved functions. Same exact parts inside.

[ledzilla]

With parts and directions from fastblackmerc, goldpanther, and limited360, I've gotten all of the exterior lights onto LEDs along with an external headlight harness to reduce the load on that relay in the LCM. And I had the warranty extension work done, too. Given how little I drive the car these days, not too worried about the new LCM going bad. I do recommend the external harness, though. Power the headlights through larger gauge wiring instead of that 18g wire running throughout. If I can get my crap together, though, I want to have my LCM upgraded, just to be safe. Fastblackmerc, I've probably said I'd be sending the damned thing out to you about a half dozen times by now. Sorry I'm such a putz. But the electronic signal flasher is sill working great.

[Bukwheet]

The issue I'm having is that there's a short where the harness plugs into the LCM. Sometimes my taillights won't come on. I can reach up under the dash and wiggle the connector to the LCM, and when you hear a relay "click", the taillights will come on.

I've had the relays replaced in my LCM 100K ago, but not sure if this issue is fixable.

Sounds like there is a loose or bent pin in the connector. I doubt it's a problem inside the LCM.

I had the recall done and My brake lights won't come on either. Have to press the pedal pretty hard. I may swap the switch to see if it helps. If not, it's going back to the dealer.

Check to see if the "tech" who performed the joke fix possibly dislodged the BOO switch or rerouted the wiring incorrectly.

The tech said the revised the brake light switch because of connection issues internally. I may throw a switch at it just to see how it is.

Sometimes the "push" bar on the switch becomes warped or bent. When you replace the switch check the connector and wires real good.

[stangracr]

I am also a ford tech. I totally agree with you. Im not gonna cut the wiring up on my Marauder.

[Invective]

I'm wondering what percentage of these failed? I read where 5% was considered a major failure? I have the recall notice in hand but lights are working fine - have Marauder up for sale. I'm reminded of a non-hack repair performed on my Mustang last year. The 20a fuse for the driver's seat would pop intermittently - replaced it with a 20a circuit breaker - no more issues so far.

[Fatssstrucker]

Thanks for the info. I have 2004 Merc Gran Marquis. Tail lights, markers lights went out once or twice over like 6 months. Finally 1 day, headlights went out.
Had the recall notices for a couple of years. I figured that I'd let a local, well reputable dealer do the LCM recall work. Never, ever did they mention that they
were going to only "jerry rig" this with a half-ass "by pass kit". The tail lights kept failing of course. Had my regular shop spend a few hours trying to figure out
the tail light marker light failure(s). We assumed that the LCM had been replaced... Replaced the headlight switch on the dash, special order, could not return, did not help.
Tried installing a new " all-in-one" switch on the steering column, did not help. Went back to dealer, said it was " body control module". Then dealer called back, said it wasn't that,
that it was the the LCM... Then they explained that they didn't originally replace the LCM, that they only did the LCM bypass kit... Which was all the recall called for: a repair to
prevent the headlights from going out unexpectedly... So now they could replace the LCM, which they should have done to begin with, for around $650. including labor...
But, this would take another week or 2, because of a back order on parts..... eye, yi, yi ...

What ever you do, do NOT let the dealer do the LCM recall repair on your car. They will butcher the heck out of your wiring. Have FBM or someone just do a relay upgrade on your LCM = lifetime repair.

This is true, but................. since new LCM's are NOT available from the dealer, the Ford approved repair is to hack the wiring to bypass the LCM. As you can see from Fatssstruckers post, that is what the dealer did..... hack up the wiring.

[BLACKMARAUDER04]

There are plenty of new LCMs available from Ford. If you have not had it replaced before, they should replace it at no charge under the original recall.
In my case, they have replaced it twice in my black under the recall. The new way would be the hack. I have 2 LCMs in my garage that have been repaired in case the ones in the car go bad.
My black still has the second one in it, my silver has one from a junkyard I purchased so I could get the original repaired.

This is spliced in between the LCM and harness.

I stupidly allowed them to do this repair as I was not aware of what was included. I was told that the original lcm would be replaced. I had allready replaced the relay twice myself with good results. after the Ford repair the door lock keypad would not work nor light up. have just limped along with remotes. never again

[PVEPANTHER]

My dealer says they can do the headlight module replacement as it was never done. After reading this, I’m guessing its a NO on the recall? Maybe I should just buy a new LCM and keep it as a spare?

Anyone have a part number, and how easy is it to replace?

Thanks

its not too hard... its under your dash. remove the trim under there and its mounted to a bracket just to the right of the steering column
