I have a 2004 F-150 Lariat Supercrew and it has no headlights ...low or high beam. I put a used headlight switch in as a new one was special order, that made no change, swapped out the auto on sensor on top of the dash with my Marauder....no change, any suggestions?? I also have jumped across the headlight switch and the lights do work both high and low when direct power is supplied, any other controls or modules that I can check? Thanks.

 

If you bypass the switch and it works, then the problem is with the switch.

That is if you are sure on what you are jumpering.
