2005 Grand Marquis - headlights go off when driving. You hear a click and sometimes they come back on and sometimes they don't. extremely dangerous to be driving down the road in the dark and to have your headlights go out. The Ford dealership advised me that it was the lighting control module that was bad. They charged me $143.75 to tell me this, then they wanted another $930 to replace it. Even though I have an extended warranty, I was advised that this particular module is not covered. I am now only driving this vehicle in the day time.

My 2005 Mercury Grand Marquis has automatic headlights which switch off leaving you driving in the dark. This has happened several times and when it does happen the lights do not work on manual and won't reset for several minutes. I am told through several forums that this is a lighting control module problem that Ford Motor Company is well aware of. I am also told the repair without additional cost of diagnosis and installation runs between $400 & $600 dollars. I feel this is a serious safety issue that Ford Motor Company is ignoring.

My wife was driving our 2005 Mercury Grand Marquis after dark and the low beam headlamps went out. Fortunately she was close to her destination and was able to navigate with the street lights. I don't want to think what may have happened on the interstate had she been heading home. Everything checks out fine except for the light control module. Dealership says this is a common problem and will cost about $500 for the part and $200 labor. We currently do not drive this car at night until we have enough money saved to get the repairs done. Someone is going to die because of this (if it already hasn't happened - we were fortunate).

Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6) I would like to report a serious safety issue with my 2005 Mercury marquis. The headlights go off after a few minutes. They will not come back on for at least 30 minutes. This is when the light switch is turned on. The other lights stay on (parking and taillights), but the headlights go off. I did a google search on this situation today, and learned that this is occurring on several year models of Mercury Grand Marquis and Ford victorias. The problem is described on the internet as a faulty circuit board in the lcm (light control module). I took my Mercury to a Ford/Mercury dealer today for a diagnostic test, which confirmed: "diag pin test isolated to erratic relay internal to lcm modu" to replace this part, I was quoted almost $800 by the dealer, installed (part price is $511). I called Ford/Mercury customer service today, 800-241-3673, and learned that there have been no recalls (tel. Call ref. [xxx]). the Ford representative gave me your website. This is a very serious problem, to be driving and have headlights suddenly go off, and remain off. It started approximately Feb. 15 and continues to present.

Back in June of this year, our low beam headlights stopped working and our dealership said it would cost over $700 to fix the problem on our 2005 Mercury Grand Marquis gs sedan. I have been out of full time work since December 2008 and I don't have the money to get it repaired. Is there any other complaints against Ford for this problem?
