Could be bad relays, Bad fuses, On my truck my dash lights, and driving lights would n come on. I dealt with that problem for months. And finally figures it out when i took off my taillights. I heard a small "pop" in my fuse box. The wiring to my tails cause the whole problem. Could even be something stupid like that. Check it out.

So the headlights only work when you use the daytime running lights? You've replaced the switch on the dash. Do your high beams work, if so when? I'm going to guess it's wiring somewhere between the switch and the DRL box, without much commitment. Good luck, man!!

Listen, Take out the head lights, and check to see if the pocket where the bulbs insert into are all gummed up with shit. Im telling you. It happend to me. I had to spray it out with an air hose then spray some electrical contact cleaner in them. Anything thats not working on your truck. Pull it off and check connections closest to it.

Diesel1114,

How did this turn out for you? I have what I think is the exact same problem with a '96 Yukon. Changed out the headlight switch and no change. Not looking forward to changing out the dimmer switch. Wondering if you found anything else that I should check before tearing into the dimmer. (tried to send you a PM, but my post count is not high enough yet) Thanks for any help you or others can give!

DRL's work only when headlight switch is in the off or parking light position, go off when turned to headlight position.

With switch in headlight position, parking lights and dash lights work, but no high or low beam.

I have the same problem and I removed the steering wheel covering and found that the wires are melted. I tried to fix them but to no availle. I think that with the tilt steering the wires break and then short out. I'm not sure the procedure of removing the steering wheel with the air bags. you can buy a whole new switch for about 110 dollars.
