Power for low and high beams goes through the headlight and dimmer switch. Flash-to-pass, goes around the headlight switch, straight to the dimmer. It still can be either part. With the headlight switch in the "on" position, check for power at the Red w/yellow stripe wire at the headlight switch. If you have power there, it's a bad dimmer switch. If there is no power, then it's the headlight switch.

Hey, I have the same problem. I've replaced the dimmer switch and the head light switch. I have new bulbs, I've done the pigtail to the headlights but still doesn't work. I've checked all of my fusses as well. Can anyone help? Thank you!

Same problem here with 02 F350 7.3 Diesel. Replaced lamps, dimmer. My problem is a short in the steering column, as I could get them to come back on by moving it. Now completely dead and am searching through the wiring to find the short.

Yep! My issue was the wire harness at twelve o'clock behind the steering wheel on the steering column. I recall just two phillips bolts and unscrewing the column adjustment lever to remove the two plastic covers. One of the leads in the harness wasn't making a clean connection. I sanded them all down, disconnected and reconnected the harness several times to "re-seat" it. No problems since.

I have the same problem. Tilting the steering column got the lights to come on, and moving the wiressin the column worked occasionally. I found the connector on the multi function switch burnt, as well as the switch (plug on top by hazard button) not sure if the problem came from the switch or if I have an issue in the harness..... any ideas??
