I was driving my 1994 mercury grand marquis gs home from work one night around 12:00 am and I experienced total lighting failure. All of the sudden everything was pitch black no lights what so ever. Every light on the car would go out and come back on simultaneously,causing me swerve, almost crashing head on with oncoming traffic. I have read online of other grand marquis' and ford crown victoria's doing the same thing.this was only my first experience with the lights. I have owned the car since jan 23,2013 and the lights continue to do this therefore I cannot drive it at night. The car is all original no aftermarket nothing but a cd player. Lights were doing this before I installed the cd player. So after this experience I pulled the light switch off only to find that the factory wiring harness that plugs into the back of the light switch had melted where the positive battery wire slot is.so I replaced the harness with a brand new one,and nothing.lights still go out. A couple weeks later I took the light switch off again to find the new wiring harness I had just bought 2 weeks prior melted just like the one from the factory, same wire slot. So now I have to go out and buy another one. I have also replaced the battery and the auto lighting control module too that didnt fix anything either.im going to try a new headlight switch and a nother new harness too. Hopefully that will fix it.but until I get the money to fix one of ford/mercury's most electrical problems I wont be driving it at night. But really this car should be recalled and ford should have to fix this. Grand marquis and crown vics have had problems with their light systems failing all the way up until they quit making them in 2011. Wish I would have known this on 1/23/2013 I wouldn't have bought mine, they just are not safe.
Headlights switch failure. *ak the headlight switch was always used manually, the wiring harness of the headlight switch locked and melted apart. *sc
This complaint is not about my car, it is about the new headlights on oncoming vehicles. Last night, driving on i680, I was blinded by a vehicle coming up behind me and this was only the first of three occurances by three different cars. Something must be done about this!!!!!
Tail lights failed while driving. Check showed bad headlight switch connectors, melted in dash.
Front headlight cover faded to a dirty white yellow color. This made it very hard to see at night. Driver had to use high beams to see at night.
Headlight switch overheats causing the circuit breaker to fail and wiring harness to burn, 2 replacement of the headlight switch. Mjs
