Running lights

Ok guys, I'm new here and have a question that is driving me crazy. I have a 99 F250 Super Duty. My dash lights and running lights do not work. I have changed the GEM, fuses, and bulbs. None of the lights work. Any suggestions?

Start tracing wires and see where you have power and where you don't. Do you have power at the fuse? Do you have power at the headlight switch? Each of these has a separate ground so it should be a power feed issue.

Depending on where the issue originates, it may be easier to feed power to that point from somewhere else than try to trace it. If you switch over to all LED, you can pretty safely tap off another source to bring fused ACC power to the headlight switch. Otherwise you could supply it with a relay - use good judgement so you aren't overloading a circuit or leaving something unprotected by a fuse.

I wouldn't say this is a "known" problem so I can't point you to a particular trouble area where these failures occur.

If you want, send me a PM with your email and I can scan over the wiring diagrams. I don't check this site all that often anymore so it may take a few days...
