mine was due to the right front fender being replaced during paint job and they failed to tighten a ground wire that attaches to the fender inside.

Problem started with no left turn signals; found blown fuse (15A) in position #16; replaced fuse and turned on left signal that immediately flew new fuse; also noticed no mirror compass, night dimming or interior temp controls; put 2nd new fuse in but still no turn sigs and hazards, fuse did not blow this time; started engine but could not shift from PARK; thought about it and removed the 2nd fuse (still good) from position #16 and it shifted right out of PARK; assume a short in some switch, probably the turn signal switch; anyone had this issue?

When we bought our 2000 Grand Marquis in 2000 (it had 6,000 miles on it), the salesman said that the previous owners said that the car was "possessed". Well, we didn't think much of at the time, but now realize what they were talking about. We've had the car 12 years.
Last Fall, (Oct. 2011) we were coming back from Louisville, pulling a boat trailer at 8:00. All of a sudden, we lost all lights on a rural highway. We pulled off, and I thought the problem was the trailer lights, which I unplugged. The lights worked, and we got home.
Two months ago (Oct. 2012), we were on a rural road (no trailer), and they went out again. I had to use emergency flashers to get home. I called the dealer, and he said they replace the lighting module ($512) on the Marquis, all the time. I got on this forum and verified that was the problem.
I got the dealer to change the module (it took two visits, as when first installed, they loosened an inline fuse) -- I got a break on the parts and labor due to family employee. Voila! All is well. In fact, I never liked the wimpy headlights on the Marquis, compared to my BMW. I had switched to high intensity bulbs in the Marquis, but that didn't help much. BELIEVE IT OR NOT, WITH THE NEW MODULE THE LIGHTS ARE TWICE AS BRIGHT.

Can someone tell me if i have an LCM mod. on my 94 grand marquis?..my lights are going on and off after i have them on for awhile,inside and headlights.

Can someone tell me if my 94 Grand Marquis has an LCM module? My lights are going off and on even the inside lights to and there's a clicking like noise coming from the right side of the steering wheel.I can turn them on auto and the steady clicking starts and they start flickering off and on.

No but there's something called an Autolamp Dual Coil Relay (headlamp relay) which is there, just right of the steering post under the dash.

This thing is driving me nuts,i covered the sensor up on the dash trying to make it think it's nighttime and will not start acting up,It will do this at night could there be another sensor for the lights somewhere?

There's a Daytime Running Light control unit:
The Daytime Running Lamps (DRL)is located at center front of vehicle, on front of upper radiator support.

I checked all around and on radiator support..nothing but 2 bag sensors.Could it be elsewhere on my 94 grand marquis? I'm also going to leave the sensor on the dash covered until it gets dark and see what happens if nothing i'll remove tape and observe..hopefully not a light show,

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?
