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.

Most recent owner complaints, unedited.
Tl* the contact owns a 1992 mercury grand marquis. While driving at approximately 50 MPH, the headlights, tail lights, and instrument panel lighting failed to illuminate. In addition, the contact stated that the dashboard was hot. The failure recurred numerous times. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 200,000.
No warning beforehand, car was destroyed by a fire that started in the left front engine area.
My 1992 grand marquis was taken in for what was a minor miss in the engine. The machanic said the computer showed a code 214. He replaced the coolant temperature sensor/switch (for computer) per the code in the car's computer. The car was returned to me and I drove it to work, about five minutes away from the repair shop. About 4 hours later I got in the car to drive home and it started missing real bad, like it was not getting enough gas and about to shut off. My car has been to a ford dealrship who wanted $1,700 in vehicale preparation cost before dealing with what may be the problem. Another machanic who use to work for a ford dealership check the car and could not remove the cod 214. The machanic replaced the cam sensor, the crank sensor, the coolant sensor, the air flow duct and installed a new set of plug wires. It is now july and I have not been able to drive my car since march 17th. What was a perfectly good car in march is now a peace of junk. Other than this problem the car is in outstanding condition. It is suspect that this problem may be electical in nature and I believe that lincoln/mercury should at least assist in correcting this problem because it appears to be based on a limiting factor of the manufacturing of the vehicle's components.
The digital dash display does not light up and ford says they do not make the part to repair it, anymore. They say they are unable to repair it and they can give us nothing for the car on trade in as they cannot resell it. Well they sold it to us. Anyway, we can't drive a car without the display...no speedometer, no fuel indicator, no nothing..
While driving, another driver signaled consumer indicating there was a fire coming from under vehicle. Consumer immediately pulled over, got out of vehicle and seconds later vehicle exploded.*ak

I want to find a dealer in or near my area to replace and install a "new speed control deactivation switch and connector shell) my car was bought from a used car auto sales place.,not an actual mercury dealer.
