I have a 2005 Mercury Grand Marquis the other night noticed headlites did not seem to be on while driving home. Interior dash lites were on, turn signals were on, the corner lights were on just the headlites were not on.
By moving the high beam lever the high beam comes on but will not stay on. I have checked the fuse and it is good. I have installed a new headlight and no change.
With the lights in auto position all other lights come on. In manual all other lights come on. Problem is just with the headlights.
I am thinking the headlight switch is messed up but then I have heard some comments about a lighting control module. Dont know where that is at. Any advice appreciated...chuck
Thanks for the info. I tried the link but I have to register first. I am waiting for approval. Just lucky we dont have to drive at night. So we can get by until I manage to get the car fixed. Thanks for your input...chuck
Go figure on this one. My wife just called me and said her headlight were working again. She had a little bear hanging off of the rear view mirror. She took it off and notice the convering needed straightening. She did that and the headlights work as they should. She locked the car with the remote and the headlights reacted as they should. We will check it out further when she gets home...chuck
Funny about those headlights. My wife had a little animal (toy of course) hung from the rear view mirror. She removed it one day and messed with the wires going into the rear view mirror and the headlights started working again. Everything worked as it should. Then they quit again and we havent gone any further with the search. Hope this helps...it worked for a week or so...
I second the Lighting Control Module. It really sucks that all of those lighting elements have to run through such an expensive little box. Maybe you could go to a junkyard and pull one out of a wreck to try. Just convince the clerk it's a turn signal flasher, haha.
Best of luck
