#46 of 245 Could a replaced transmission speed sensor cause lights to go on by texasgal1

May 27, 2007 (8:14 pm)

I have a 2000 Grand Marquis. Recently had the transmission speed sensor replaced. Now headlamps and interior lights are going on and of by themselves. This goes on all night long. Had to turn the head lamps from auto to off to stop headlights from coming on. Could this be connected to the replacement of the tranny sensor?

Two winters ago the interior lights in my 99 Grand Marquis began going on and off throughout the night. (Not the headlights). I took out all the interior bulbs. It was easy getting used to life without them. This spring I put all the bulbs back in and within one week they started again to go on and off throughout the night. I again removed the bulbs and am living without them.
Other than that, the car has reached 103,000 miles without any problems. I change the oil,changed the serpentine belt,changed the spark plugs,coolant,and brakes and that's it!

Regarding that light problem on the 2000 Mercury GM, a mechanic suggested I let it dry out real good, as it had been raining really hard and I drove in a driving rain. He said some Fords have a problem with water getting in the electrical. As of today it has not repeated the problem. I am hoping this holds. Other than that it has been a great car.

What other accessories do not work? The fuse for the lighter enables other minor electricals to function. If the others function, it is the unit itself.

#51 of 245 Headlights work intermittently by nateman7ahc

Hey gang,
 
My headlights ('03 CV) were turning themselves off after about a minute of burning. It didn't matter what position the headlight switch was on. Sometimes I could get the lights to come back on if they were off by turning the switch to off and then back to on. But the lights would always eventually go out. I found I could hold the turn signal back in a flash-to-pass position as a temporary fix. Finally took the car in and needed a new multi-function switch in the steering column and when that burned out it also took the lighting control module. This was $900 and not at a dealer, a local shop. Hope this info can help someone else. Overall, car has been pretty good--also had to replace the climate control module (also $900).

I have a 2000 Grand Marquis, and the dome light started to come on on day. It would light up after my car was parked, and stay on. Eventually it drained a battery, so I tried another, and it drained that one as well. Now I disconnect the negative terminal from the battery everytime I park it. I have been doing this for sometime, while I have tried to look for the problem. Any help would be great.

The short term fix: pull the bulb.

#55 of 245 Wiring Harness by pesully

I am looking for info on the 2006 GM harness. Does it have all the connections for keyless entry etc even if they were not installed? So if you got the module you could plug it in?
