Ow, my ears. And my eyes. I would say 'no offense,' but really, you need to uncaps, and also get a period in there a couple of times.

Anyway, the only help you can get on this is that, if the bulbs are good, then the circuit is the problem. Bad grounds will cause this, and are *relatively* easy to check. Find the ground wire in question, find the bolt that attaches it to the chassis, take it off, clean it/sand it, put it back on.

If it's not the ground, then it's the incoming signal wires, and now you're in hunt mode. Check each section, going backwards from the lights, checking both for continuity and shorts.

It will be tedious. It will be time consuming. And it will drive you bonkers. And you will need a wiring diagram to figure it out with, and proper electrical check tools such as a multimeter, a wire tester (the sharp ended device that lights up), and probably a friend or two.

I'm sure you checked, but all the fuses are good, right?

Good dang luck to you.

You might want to check your ignition switch, but I have a feeling it's the Multi-Function Switch and I say that because a good friend of mine just had the same problem and we found out one of the wires had come loose from the terminal.
