Mercury Grand Marquis Malfunctioning Headlights
Mercury Grand Marquis Problem
Model Year Affected: 2005
Average Mileage: 79,113 mi (53,082 mi - 109,000 mi)
Headlights..... Going on and off with no warning. After much research have found out it is the Lighting control module. It is a defective part on a 2003 model. I have called Ford Motor and they dont care!! They say they have not had enough complaints... BLAH, BLAH! This is a SAFETY ISSUE. I am going to go into a B***CH mode and fight to get this fixed by them. How would they like to be driving down the road and have their lights just go off and on!
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).

The headlights are set to auto mode and they have started shutting off at night for no reason. They will not work when switch is turned to manual or auto. Very dangerous and I have heard that this is a common problem. File complaints with federal and state gov'ts - Consumer Product Safety Commission.

First of all, my headlights would not go off.. I had to remove the fuse in order to turn them off. It corrected itself. Now they won't go on, no matter which mode the switch is in. I was told that the problem is in the turn signal/high beam switch. I'm waiting for my mechanic to get the part.
