I am currently having problems with my 2004 mercury grand marquis with the head lights not coming on or going out. All other light stay on. Turning the light switch on / off and it won't come on. Same symptoms in auto or manual headlight mode. If I stop the car it will come back on. It then might go off after a while. I see others have had this same problem, this was confirmed by my local ford dealership. Very common problem with serious safety concerns. Dealer tells me it is a failure of the light control module (lcm).
