Hi all. I was having a problem where my headlights were turning off every time I would turn my directional signals on (2004 F150). Started out that it was mainly during left turns, but recently it affected right turns as well. Did a bit of google research as well as asking a mechanic to take a look at it while he was repairing something else, and all signs seemed to point to a bad multifunction switch. So I replaced the mfs, and now my headlights don't work at all. The high beams work when I flash them, but not when I click them on fully. The parking lights work as well as the directionals. Took the truck into Ford and they are saying the headlight switch is bad. Does this sound right? After blowing $100+ on a mfs I'd hate to drop another $100 on a headlight switch only to find that it too, doesn't fix the problem. Not to mention NOBODY around here seems to carry the switch in stock.
I checked the 2 fuses for the headlights and they looked fine. Any help would be appreciated.

Try getting a headlight switch from a junkyard. Also, if your truck has the auto-light feature, there is a relay involved as well that could be out.
