Help: LCM for a 2003 marauder

[V-Rauder]

Does anyone know where to get the best deal on a LCM for a 2003 marauder. The dealership is talking $500. What?

Is yours bad?

If it needs the relay replaced send it to me with $15.00 and I'll install a heavy duty external relay. PM me.

[SC Cheesehead]

Check your local salvage yard.

The LCM that was originally in my car was a 3W7T-13C588-AH. I replaced it with a 4W7Z-13C788-BB that came out of a 2004 Grand Marquis.

I also got the following info from RoyLPita. In addition to the 4W7Z-13C788-BB, a 4W7Z-13C788-BC will work, and these additional p/n's should also be compatable: 3W7Z-13C788-AA, 3W7Z-13C788-AH, 3W7Z-13C788-BA, 4W7Z-13C788-AB, 4W7Z-13C788-BC, or 4W7Z-13C788-BA.

Expect to pay between $50 and $100, depending on the yard.

Alternately, you can replace the faulty relay in your current LCM for less than $10, or have FBM do one of his super duty external relay retro-fits. :up:

I got this link from Twin03. My lights go out sometimes, but a quick tap (or two) by about the brake and they are back on, probably won't work someday or something may be loose!

Take it from me, there are a limited number of "taps" that you can rely on to get the lights to come back on. Sooner or later the relay will fail and then you're http://www.google.com/images?q=tbn:3tE6XCXwhl9GIM::b uelahman.files.wordpress.com/2008/10/saupload_screwed.jpg&h=94&w=90&usg=__NCsQqDajCncntoeDjtZBOwr8 aVw= (http://www.google.com/imgres?imgurl=http://buelahman.files.wordpress.com/2008/10/saupload_screwed.jpg&imgrefurl=http://buelahman.wordpress.com/2008/10/06/&h=410&w=396&sz=121&tbnid=3tE6XCXwhl9GIM:&tbnh=125&tbnw=121&prev=/images%3Fq%3Dscrewed%2Bphotos&hl=en&usg=__-SpFR3K5vS0Q033k1e4Ghmh0E64=&ei=MqEBS7v_FMb7nAe0z-kP&sa=X&oi=image_result&resnum=1&ct=image&ved=0CAcQ9QEwAA) until you can do a real fix.

[Richy04]

Dont buy a new one, get another used one and send it out for the repair or fix it yourself. You don't show where you are but I am sure there are quite a few members here with soldering skills who will repair it for you. Its a crappy relay which goes bad. It seems that most if not all of the MM electrical problems are based on crappy soldering, relays or water intrusion which causes these failures, most are made by the same supplier to Ford since the boards in all of these items are near identical in design.

The BCM (blower control module) fails at the terminals and a good workup reinforcing the solder traces at the blower output part of the module will restore it.

The LCM fails because the relay is not robust enough to carry the current to the headlights and the relay fails after a while.

The heated seat switches fail for the same reason, the traces lift or loosen and the leds then flicker on and off. A quick look at these boards and you can tell they come from the same putzes. All of these are repairable if you are good with a soldering iron and some minor electronics knowledge.

So do I need a relay or the LCM, or both???:confused:

So do I need a relay or the LCM, or both???:confused:

If you want to do a quick in/out fix, go with a used LCM. But like richy04 said, the issue is with a relay within the LCM, not the whole LCM.

If you've got the time, order up a replacement OEM relay or get a HD replacement and swap out the defective one in your LCM.

Third alternative: Buy a used LCM, swap it out, send the original to richy04, fastblackmerc, others, have them do the relay replacement and return. That way you can swap out with the upgraded unit and have a spare on hand to help out another Marauderer if needed. That's what I did.

[V-Rauder]

Fastblkmerc,
Yeah I think mine is gone. Because i used to wiggle the lcm when tapping it wasn't working it. According to my mechanic i broke something off of the motherboard. I think my only option is to get a new or used one. I don't think mine can be fixed.

[RF Overlord]

If you get a used one or one from a junkyard, do yourself a favour and send it to FBM or Richy04 and have them replace that relay now. You never know if the unit you get has the exact same issue. I can also do the work for you, or if you have a friend with experience working on printed circuit boards it's a simple fix.

Do your WALLET a favour and skip buying a new one...Ford's prices are ridiculous.

Send it to me and I can check to see if anything is broken. I doubt it unless you opened up the LCM and broke something in there. BTW I test everyone on my MM before I return it.

[V-Rauder]

FBM
I decided to go get my car from the mechanic instead of buying a new one. After reading some of the post on here I'm hoping I can save money. What he said was broken was the White part that sticks out of the LCM it is completely disconnected from the board. Can this be repaired? Also where can I send mine? How long will it take to fix as I need it ASAP. You know I can't drive at night. I'm in Chicago. Hopefully you understand what I'm talking about when I say the white part. Where the lights plug into the LCM. It has the numbers on it.

[Spectragod]

Pictures would be great, it sounds like the connector just came off the board, if so, it may be able to be re-soldered. Pics first, lets see what we're getting into.

[SC Cheesehead]

Do you mean the white plug-in shown right in the pic below? Did it break off completely?

http://www.crownvic.net/bok/LCMrelay/03LCMRELAY1of5.jpg

IMO, If it is completely separated, you may be better off buying a replacement LCM from a salvage yard, there are a lot of connections running up to that plug.

Here are the photos

[Breadfan]

See if you can get clearer pictures of the board.

Most PCBs (printed circuit boards) are multilayer with the copper interconnects running through each layer. If this plug was forcibly pulled out it could've damaged the PCB.

We'd need to see the board better to see how it broke off. You may need a pic of the other side.

Yes, I can kinda see from the pics above, but clearer could help be for sure. It looks like it could be resoldered, but it could be a tough job unless you're a skilled solderer. A salvage LCM may be cheaper...

Here's what it looks like.

[MrBluGruv]

if it's just the solder connections that are broken, with a little patience and a steady hand it should definately be fixable. Just make SURE you don't accidently bridge some of the pins together while soldering.

[GordonB]

Need some focus factor here! GordonB

[Breadfan]

Yeah, it's hard to tell. If you aren't sure, then you probably won't be able to repair it, your best bet is to find someone with good solder skills and let them look at it, and see if they can fix it. If not, salvage yard.

[ntd]

I have a spare lcm with an external relay for the headlamps. Send me a pm if your interested

[twin03]

Try ebay bro...

[joefireman18]

Sorry if I mised this. Does anyone have the actual relay part number.
I tried the part number given in the pic at the electrnoics shop by me and no go? Just wonder if I have it right. Thanks men:cool4:

The whole point of replacing the stock relay with an external heavy duty one is to eliminate the crappy stock one. If you replace the crappy stock one with a crappy new one you aren't gaining anything, are we?

I was able to fix it. Much worse than it looks in the picture. I'd tell you all how I fixed it ...... but hen I'd have to kill y'all.......... :D:D:D:D:D

More than the connections were broken.... It was a mess.

[fastblackmerc]

The repaired LCM was just installed by V-Rauder. Will let him tell you how it worked.

Here's info on the OEM relay, NEC EQ1-11111S.
http://www.worldproducts.com/pdfs/eq1.pdf

You can order them through Mouser electronics: www.mouser.com (http://www.mouser.com)

FWIW, you might want to retrofit with the HD relay as the OEM replacement will probably crap out on you again; mine did.

Hey John, no need to apologize, that's what we're here for, to help each other out.

+1 Don't spend money on a new module, you'll end up spending $400 -$500, and the problem will re-occur anyway. fastblackmerc has the fix for the problem, quick and very reasonably priced.

Wise decision, he can get you fixed right up.

I have to figure out how to wrestle the LCM out of my car with adjustable pedals. This is going to be fun.

I have to say once the issue starts it just continuously gets worse over time it seems. I have a feeling I will have to hold the high beam in for the next few nights until I can get this situation resolved. Tonight I had to tap the LCM around 4 times during a 15 minute drive home from work. Fun stuff.

[fastblackmerc]

How to remove the LCM from a Marauder, Crown Vic or Grand Marquis.

The LCM is about the size of a brick and is located just to the right of the steering column, in front of the gas pedal.

There are 3 electrical connectors on the LCM.

Remove the bottom two connectors by depressing the tabs and pulling on the connectors.

Remove the 2 mounting screws with a 7mm nut driver or socket.

Push the LCM towards the gas pedal while rotating it up towards the roof. Once it’s free of the bracket, pull the back of the LCM down towards the floor.

You should now be able to release the last electrical connector.

Just reverse the steps for reinstallation.

[stickyheat]

Sounds like a straight forward operation. Thank you for the tutorial.

Please let me know how to proceed with sending it to you for repair.

Thanks again,
Omar

Is yours bad?

If it needs the relay replaced send it to me with $15.00 and I'll install a heavy duty external relay. PM me.


And I do not think I need to remind any of the members here he does a excelent job and has from the very begining, and he has done many for me his service and quality is superb. And to me that is what counts.

[fastblackmerc]

Unfortunately I have to charge more than $15.00 for the LCM repair.

I do offer two options.

1st option: Send me your LCM, I repair and return it to the post office the same day.

2nd option: Send me a PayPal payment, I send you a repaired LCM. When you return your old LCM I refund the core charge.

I have over 75 satisfied customers to date.

You know Jim we have never met, you have my endorsement and my support, you have a quality product and have served this community with a ZERO complaint, and you you did not copie it from a another member or vendor.

[Original quote from Babbage]
Geesh Dennis, it's obvious you are jealous of Musclemerc but do you have to follow him around like a little dog yapping all the time? :bigcry:

Please DO NOT act like I copied anything from FBM, he did'nt originally come up with the LCM fix as a matter of fact he is not the only member here that is capable of using a solder iron. I started soldering as a lad replacing tubes in my Dads old tube amps but thats another story.
Here is a link that started it all for repairing LCMs, I dont see FBM contributing anything to this DIY thread:
http://www.crownvic.net/ubbthreads/ubbthreads.php?ubb=showflat&Number=1159835&page=4#Post1159835

You can also read the sticky in the shop forum, looks to me MENINBLACK was the first member to perform a LCM repair, so I ask did FBM steal it from him?
http://mercurymarauder.net/forums/showthread.php?t=48102&page=3

Bottom line is if you post any how to on the net and do not have a Patent application on the repair or the parts used to do the repair, its free for anyone to use with or without your permission. My threads included.

Maybe FBM can become a Vendor like you and I are Dennis. I know he loves this community and the Vendor fees are very affordable. The Admins will gladly help you out with the info and help you get started :beer:

Oh yeah Dennis so much for this comment you recently made:

You dont want this fued between us to go away you dig up this thread to cause beef between myself and FBM.
