    I seem to remember reading several posts about a wiring harness on the fender well chaffing on some kodiak models and weird lighting issues.

    Might be worth a poke around the engine bay to look.....

    Thanks I'll check the harness out. I do have DLR's and I did make sure the Ebrake is off. I just don't have the low beams. It's wierd. I think maybe it's the high low switch in turn signal lever. I guess I have to pull the wheel and r&r it. Thanks

    Question

    I've looked at the wiring diagram and what I see is that if you have DLRs you are getting power to the low beams. The low beams get there power through the DLR relay. It almost has to be a bad relay.

    Ok, I had swapped out the reverse relay with the DRL relay. They both use the same relay. I wonder if they could both be bad?
