where do I take my car to get the headlight fix
Check the fuses. Your owners manual will tell you which one it is. You can get fuses at any auto parts store but I recommend always having some spares in the glove box.
Sounds like the lighting control module (LCM). These LCMs have been so troublesome that Ford has extended the warranty on them. Take it to your local Ford Dealer for a free repair! HTH. -Jim
Did they extend the warranty back to 2004?
Yes, a guy at work has an '03 model and he took advantage of it last year. HTH. -Jim
