2003 Mercury Grand Marquis Q&A
2003 Mercury Grand Marquis Question: Headlights do not work
Not the fuse and not the switch. Could it be LMC? how much to repair - Visitor
How did you rule out the switch as the point of failure? 90% of the time, your failure is due to the switch and wiring connector at the switch. Look for burnt terminals. Did you eliminate the switch as an issue by replacing it, or by circuit testing the terminals? The other 9% of the time, bulbs are burned out. And the last 1% could be a wiring issue elsewhere or the LCM...I just doubt it significantly. - DaveJHM

Every few months the headlights in my car will not go on. They will normally go on automatically at dusk but when this happens I can't even turn them on manually. My high beams won't even work un...
