Headlights stop workinging without warning.

My Grand Marquis with 59000 miles has same problem as all the others reported here.... Lights simply go off... Holding the flash on provides light and overrides problem....temporarily. I called NHTSA 888-327-4236.... Filed complaint. They gave me the number for Ford 800-392-3673...Told them the problem and that I had filed a complaint with NHTSA.... Ford looked in their files and said they had a "Consumer Satisfaction Letter" on file dealing exactly with my problem. While I was on the line, Ford called my local Lincoln/Mercury dealer, Ford told the dealer service guy (Mike) my problem and that Ford has a "CSL" on file covering my problem. Mike came on the line and we made an appointment for tomorrow. Ford and the dealer confirmed that the fix including diagnostics,labor and parts will cost me zero...... Will let you all know how it all turns out........Now two days later.... Just returned from Lincoln/Mercury dealer..... Replaced Light Control Module no cost to me. Ford now has extended warranty on this part (15 years/250,000 miles) and has sent a letter dated April 21,2014 to all owners of cars with this part. Fix for free...or get refund if already repaired. Good thing because the dealer was going to charge me $819!

Is it on 'auto' and what is the delay set to? Or is your model strictly manual controls? .............................................[7/26/12] never mind I was mistaken in thinking that you actually were looking for assistance with an automotive problem which asked a question that needed some feedback ....my bad.

I own a 2005 Grand Marquis 4.6 V8 that I love. 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). Apparently this is a common problem for this car around this mileage and age (6 yrs old). Ford denies there is any problem. Found 26 complaints about this on another website. People owning this car should be aware of the problem and be prepared for it. Headlights do come back on if you turn the headlight switch back and forth, or stop and let it cool down for a few moments.

I have had the same problem with my Mercury. The light control module is very expensive, so I found an aftermarket part that, when installed, my headlights worked! The cost was only about $100 instead of $500, the downside: my interior lights don't turn on when unlocking the doors, the horn does not sound when alarm is activated, the turn signals sometimes don't work, and sometimes I can't put the car into drive or reverse! I have to wiggle the part a bit to get some things to work! At least I have headlights, tho I will be spending the $500 to get the real part.
