For the second time in approximately 1 year, the headlights started turning off an on when driving home on the freeway 4 nights ago. The first time this happened a year ago, the headlight switch , burned wire and burned connector were replaced. The car is currently parked as I feel it is unsafe to drive with the overheating wiring.

Smoke was coming out from under the hood while driving the car using cruise control. Pulled over and checked the fluids on the car. No problem. Started driving again and began to have problems. Pulled over again and saw smoke then flames coming out. Car was a total loss.
I parked my 1992 mercury grand marquis on friday, 2/5/10, next to my home. Shortly thereafter, while in the house, I heard a "pop." when I looked outside, the car was on fire. I called 911 but by the time they arrived, found a fire hydrant that was not frozen, most of my home was on fire. The destruction was awful. I have not been allowed back in the house yet.
Tl*the contact owns a 1992 mercury grand marquis ls. While driving 55 MPH with the cruise control activated, smoke engulfed the front-end of the vehicle followed by an underhood fire that caused the front windshield to break. There were no injuries. The fire department was unable to extinguish the flames with their equipment and the vehicle was completely destroyed. She was in the process of notifying the manufacturer to inquire about the level of safety of the cruise control. The failure mileage was unknown.
I have pictures of the fuel pump I took out of my 1992 mercury grand marquis. The car had coughed to a stop and I suspected the fuel pump. There was no pressure in the fuel rail so I pulled the pump out of the tank. I checked the pump with a battery and it ran fine. Then I started looking at the fuses and found the 20a pump fuse blown. Obviously there was a short somewhere. As you can see by pic 2 the short occurred when the "hot" wire insulation was worn through on the float bracket. In order to blow a 20a fuse there must have been a spark. Fortunately, it appears that the contact point was under the level of the gasoline when the short occurred and nothing else happened. If the point had been above the gasoline in the vapor area the results could have been much different. Pic 3 is how I routed the wire before replacing the assembly back in the tank. Btw you can see that I did use a new fuel pump. I still have the old one. I sent a message to the ford motor company through their web site but have not heard anything. As of now I am afraid to drive my 1997 grand marquis since the design is identical. I guess my next stop is the dot or better yet youtube. I never did understand putting an electric motor in the fuel tank. Jerry holland
