High beams wonky

Post by gthberg »

So, I went in for my safety inspection today, and discovered a really weird issue with my headlights. My low beams work just fine. But when I turn on my high beams, here's what happens:
Drivers side low beam goes off and the high beam turns on
Passenger side high beam doesn't turn on, but the low beam turns to high beam.

Any ideas?

Maybe grounds near the headlamps?

I had something similar when I was swapping the sealed beams for Halogen H1/H4 headlights. I blew a few fuses and with blown fuses I'd get a high beam on one side and a low beam on the other. Seemed weird but thats the way they are fused. There are two fuses for the headlights, I can't remember which ones though.

Thanks, guys. It was the fuse. Weird how they're fused...with the #2 fuse blown, one of the low beams should have been out, you'd think. Anyway, it's fixed now. Thanks for the help.

I stand corrected....it’s not solved. It keeps blowing the same fuse (#2). Zinnocoupe, did you ever figure out what was causing the fuse issue? I, also, did the H4 upgrade.
