I HAVE A 2005 EXCURSION. THE HEADLIGHTS JUST QUIT WORKING. THE DRIVING LIGHTS WORK. THE HIGH BEAMS WORK WHEN THE SIGNAL LEVER IS PULLED. IVE HEARD THAT IT COULD BE THE MULTI-FUNCTION SWITCH?

 

Do the parking lights work? And on a long shot maybe both bulbs are out. Maybe?

And did you try manually and automatic?

 

Maybe your light switch on the dashboard is faulty. Try your automatic lights at night and see if it lights up.

 

low light sensor is working properly and activates parking lights. i have had this trouble intermittently and would fix itself without any input from me. now they wont come on at all

 

ever get a fix? i have the same problem with my 05 F250.

 

Check fuse box in the engine hood.
Think the ones for headlights are 10A mini's. When you pop off top you'll see layout for fuses and your owner's manual will have the Slot/Fuse needed in it.

I had that issue with one headlight, swapped out, and blammo working again.

 

fuses are fine. pulled switch...worked for a while....then low-beams stopped working again!

 

anyone have the circuit diagrams for a 2005 F250 headlight & DRL circuit?
