Headlights wont come on - 2003 Ford Expedition

Headlight switch? Headlights don't use the fuse panels. Is there a delayed off for the headlights? If so, this module might be defective.

there is a few fuses for the lights

Replace the headlight switch and the wiring connector to the headlight switch.

Check the electical components or it could be a bad fuse or the wiring harness that feeds power to the headlight may be corroded or shorted out. And the headlight switch that allows you to change between the low and high beams may be broken.

might be the headlight switch,check to see if you have power at your bulbs with the headlights on if you don't check headlight fuses and relay.

might have to replace the headlights/bulbs. I have an 85 rx7 and I didnt have low beams only high and I replaced both headlights and now they work.

Headlight switch on dash???

I had an S-70 with the same problem what happens is the headlight switch tabs that hol it together broke and the switch was slightly separated and connection was not there for the headlights and also check the high beam see if headlights come on i dont think it is a relay or fuse??? proballally the headlight switch and easy to replace you even can use one from an 850 model
