2005 Mercury Grand Marquis Problems
The car had 64600 miles on it and the headlights started going out while driving, which can be very dangerous. The problem is in the Light Control Module which is an expensive part (around $500 to $600 + labor).
A spring in the seat belt buckle may wear or fail, causing the airbag light on the instrument panel to illuminate. Failed buckles will require replacement.
The throttle position sensor (TPS) may fail. Common symptoms of a defective TPS can be rough idle, hard starting, hesitation on acceleration, poor fuel economy, and stalling.

Dealers will replace the lower intermediate steering shaft and inspect the upper intermediate shaft and steering column lower bearing for damage, they will be repaired or replaced as necessary.

Headlights tend to turn off on their own while driving down the road. People owning thi...
Had problems with the lighting modual at about 45,000. (BIG $$$$) Now experiencing problems with the ac-heater fan speed control. Replaced the a/c fan motor at about 35,000 miles. Car otherwise OK. Electrical system sucks.
