I just removed the headlight switch and in the harness one of the wires where connected to switch was burnt and melted,i hope that's the problem..now to find a new harness i guess...think the switch is good or replace to be on the safe side?

sounds like the switch overheated. I'd replace it unless it was punishingly expensive.
"Fire...good. Fire in car....BAD!"
sorry about the DLC...that's what the manual told me when I looked it up for you. In the diagram it looks to be more to the right (passenger) side of the radiator shroud, next to the outside temp sensor. This is a '94 GMarquis, right?

Great! If you can, maybe feel the harness to see if it's getting hot.

Yes, it has an LCM. The part is ~ $500.00 from Ford and they will install it for another $400.00. If you are handy and know how to solder, this problem can be fixed by replacing a relay on the LCM circuit board. The relay is available on line for ~ $0.85 + ~ $3.00 shipping from Mouser Electronics.
Somewhere on this string are pictures of where the LCM is located (under the dash to the right of the steering wheel) and the part # of the relay.

Actually this was in reference to 2000 - 2006 Merc. Gran Marquis. Not sure about the '94.

HI, I posted in here before about my 94 Grand Marquis about my lights going on and off.Well i'm back darn it,They 're doing same thing i replaced a burnt harness on my light switch,it worked for a bit.Come's to find out mine has a Wiper Control Module where the LCM is now i think.It was clicking i thought it was an LCM.So i'm wondering does it have anything to do with the lights?..I can turn on my wipers with the Multi switch and it will start clicking real bad..I did not replace the light switch itself just the harness...The wiper Control Module has relays in it like the LCM does.

In reference to question #234,does this sound like a headlight switch wiring problem?.

My 94 Marquis headlight switch harness is 9 prong,when i replaced it i had to remove 2 wires from it because the burnt one had only 7 wires.Is that the right harness that was on the car to begin with or does it need a 7 prong harness>?....i'm having light problems the one i replaced had a burnt wire.
