No Lights

[Bradley G]

Yesterday, my foglamps went off by themselves(switch still on)
I noticed the little green lamp on the headlamp switch, was out too.
Today, I have no headlamps.
I have the DayTime Running lamps, so I am guessing, it is the headlamp switch.

[Bigdogjim]

Well I have not had that issue.

I have however had many other enconters with lights and wipers.

Keep us posted please.

One of my fog lamps stopped working about 2 weeks ago. Bought a new bulb and still didn't work. Took out the bulb and the plastic piece that connects to the bulb and plugged into my brother's Marauder where it works.

???:dunno: ???

Anyone know what the problem could be if it is not the fuse (since the passenger side fog lamp works), not the bulb or the plastic connector piece that holds the bulb (since it works in my brother's Marauder)???

First check:

Fuses
Circuit breaker(s) (Replace with a fuse of the same amp rating to test)
Relay(s) The fog lights DO use their own seperate relay, and oen for the cut-out, located in the under-hood fuse box:

Swap it with the A/C cutout relay temporarily to test.

I would suspect the LCM before the headlamp switch, they seem to be very touchy on the MMs. Also, DRLs are not activated with headlamps ON, is your switch on auto or headlamp on position?

[Bradley G]

The oem lamps were returned both top and botton.
The TSB was very explicit no aftermarket bulbs.
These two threads could be merged.
The "Warning aftermarket bulbs" one.

Possibly a defective headlight switch.

Both of my Fog lights went out at the same time, but my green light on the switch still lights up.....any findings on what your problems were? ....I am going to trouble shoot it with Wes this weekend. Any one know were the LCM is located?

[Bradley G]

Same as mine; (sometimes)green light on, no foglamps on.
All the connectors , were melted.
I think the LCM, is in the headlamp switch.

Did you ever get it fixed...if so what was the fix...a new switch?

LCM is under the steering column.....;)

[Bradley G]

When I heard the $ of an replacement switch, I thought the LCM was built in!

Trace your fog light harness back under the fenders.
There is another connector to the main harnesses.
Make sure these are tight and they don't have water inside.
If you do see water inside, fill the connectors with silicone grease
before putting them back together.

DON'T USE VASOLINE. It will destroy the plastic connectors over time.

LCM is separate and as I recall about $600.00......Mine was replaced by warranty when the turn signals quit!!:mad2:

BTW....dealer can trouble shoot through OBD II and their hand held gismo....Will tell the story!!:cool:

Good Luck Bradley!!

Check the fuses and relay first. Unfortunately I have seen several LCM failures lately. Costly, and definitely should be a more robust component.

[Bradley G]

OUCH!
I have not had any problems, since the dealer put me back to stock(bulbs).

My Fog lights went out today No green Light either. Help

[Bradley G]

Look at the connectors, where they plug into the bulbs.

I got one for you! My headlights cycle between on and off. It will stay on for two minutes, then go off. Two minutes later, they will come back on. Fog lights stay on no matter what though. Now, I did have my friend take a quick look at the fuses and the power box, the big box on the passenger side fender. I believe that's what is called. Fuses seem to be okay. How hard is it to get the headlight switch replaced? I have the extended 6yr 60,000 mile warranty, you think this would be covered?

[Bradley G]

Premimum care should cover that

Mine is doing the same thing. Took it to the dealer yesterday, they said it was the LCM. Wanted $900 to change it, $450 for the part and $450 for labor. They said it had to be programmed. Is this the case or is it a direct swap? Ordered the LCM off of 1stfordparts.com for $230, I am hoping I can just switch the two units.

[fastblackmerc]

I think it's a direct swap and doesn't need programming.

[Bradley G]

Find another Dealer! I watched my pal install it, while I drank a cup 'o joe (bragging about the weekend @ the dragstrip). Took no longer than fifteen minutes, including the wait in line, for the part. No programming necessary! the whole thing took him less than fifteen minutes

Bradley, as i mentioned at the track, the LCM's have a tendency to suffer from failure of the main light relay inside. This causes all lights to go off and on unpredictably until eventually just staying off.

There are 3 solutions - a new LCM is the easy one. You can also take it apart and replace the relay, or you can do as I did, take it apart, remove the relay, solder wires into the relay connection points, run the wires out of the LCM box and to an empty relay point in the main power distribution box under the hood, then simply plug in a standard Ford relay. Mine hasn't failed yet (60k) but if it does, i can just plug in another relay!

Most people who have these failures drive with their lights on much of the time.

Do you have a source for the correct Power Distribution box contacts to do this?

[Bradley G]

Since I will be out of ESP shortly, I will be interested to know, what exactly to do. Especially, since the entire LCM module, is well over three hundred dollars. (I read you can get them for two an a half) You are absolutely correct , Tony my lights are always on if the ignition is turned to the on position, because I have a Daytime running light module installed. Just like the Canadian versions came with, from the Factory. Got that Logan?

Bradley, did your car come with the factory plug in the harness for the DRL module or did you have to splice it in?

[derik]

This was suggested as a fix:

[Bradley G]

It required splicing, I had the selling dealer install it. I was not aware of a plug and play version.

That is what I would need, for next time ------------Thanks for sharing!

wELL A YEAR Almost to the day, the lights went out again.
The LCM part gets a 12Mo 12000 mile warranty.:sweat:
I'll see if I can keep the part that is taken out.

[Bigdogjim]

WOW! The should be covered if a Ford or L&M dealer did the work.

[MarauderBoy]

I seem to be able to only get this half right. I had all the symptoms(periodic off, on, off) and now its out completely. Only thing is that it's the driver side light only.

Could the LCM impact one light only?

[Bradley G]

Well it turns out the sockets were unpluged from the bulbs.
My Mechanic buddy who was troubleshooting it, asked me ,"Who don't like you?"
