Alright I'm hopin this is the right forum, please redirect me if it isn't. '02 Cavalier, headlights were randomly going out, now I have it to where they work and the DRLs are ok, but now if I hit the high beams the bulbs turn off and then of course the service light comes on. My question is will it be a wiring issue, I have checked the fuses and they are fine, I'm at a loss here. I installed aftermarket fog/driving lights but they are on a dedicated circuit. It frustrates me cause a simple 12v DC system has me stumped. The newer cars get, the more complicated they get. Any help is appreciated I am leaving country soon to play in the sandbox, inspection is due while I am gone so I have to finish it before I leave.

I suspect a relay is on the way out or a faulty ground...

I thought relay as well but I can't find any labeled for the headlights. Where this may be located..........?

I believe it is betwen the radiator and tne bumper.

Ppreciate it man I'll take a look and see what I can do. Let yall know if it works.
