1999 GMC Jimmy headlights not working

I was driving one night and looked down at dash and saw that the high beam indicator light was light up like half brightness. I tried turning them on and had no high beams. The next day I went to mess with it and I then had no low beams either. As on as headlights are meant to be on the fog lights dont work either. I have checked fuses, relays, and the switch. The switch sends power but the headlight power relay receives no power to it as I found out with a test light. Idk what it could be.

    Might not matter, but what model and year GMC?

    I know you've checked the fuses, but I'd recheck them and look for other fuses in places you may not have checked. (link).
    Try skimming through this discussion for other ideas (maybe a grounding issue?):

  • Ground works. Ran temporary power to them and they work so ground is good
