86 headlight issues

I recently bought an 86 iroc z28 with some headlight problems. The driver side headlight comes on but the passenger side comes on real low. Also the driverside blinker works but the passenger side blinker doesnt blink on the dash but the headlights blink instead of the flasher. I assume its just a wiring/relay problem. Has anyone dealt with these problems before? Any info would help. Thanks.

Sounds like a bad ground. When funky things happen its usually a ground issue. Dim and blinking headlights are definitely funky.

Have you tried replacing the switch? Do you have an aftermarket alarm? The circuits are getting crossed. I had a 97 Nissan truck that whenever it rained the left blinker light would just come on and stay on, It had a Uhaul trailer wiring box wired in. When I removed it the problem went away.

I havent tried replacing the switch and yes it does have an aftermarket alarm...it was disconnected when i bought it and i reconnected the wires...but ill try to find the cross....Thanks.
