Headlights will not work. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi all, I'm having a issue with my headlights but before I start cutting up my harness I would like to know if my mismatch of parts could be the problem. So my cab is a 68 gmc and my front clip is a 70 chevy. The headlight harness plugs into the fuse box just fine but the only thing that comes on is the turn signals. Even if the headlight switch is off. Is there a difference between the 68 gmc harness and the 1970 chevy harness besides the dual headinghts on the gmc. Is that why it won't work. I think my grounds are good. What do you guys think? Any help would be great.

Check the high beam switch that's on the floor, the power for the headlights goes through that switch. That was the issue I had with my headlights not working, bad switch.

I think everyone has this issue at one time or another.
