It's probably your Lighting Control Module LCM. Factory recall should have been done, Ford will pay for some repairs. Get a rebuilt one from EBAY.

It's under the dash, above the streeing column. Kinda hard to get at. Try Googling it. I paid someone to do it because of my neck.

Bad bulbs, blown fuse, bad ground at the bulbs, bad headlight switch, bad Lighting Control Module, Those are the posibilites, check the bulbs and look for corrosion first, as well as fuse.
