My high beams are only working sometimes. It started out where they would take a second to turn on. You'd switch from low beam to high beam and it would go dark and then a second later they would turn on and be fine. But now tonight I get in my car and they won't work at all. Finally 15 mins into the drive I finally got them to come on but then a car came by and I turned them back to the low beams and after that they won't turn on again.

 

What is going on?

 

A little background first. When I got the car 3 years ago I noticed someone had done something to the wiring for the headlights and did a terrible job by not soldering and using a cheap crimp connection and no heatshrink leaving the wires exposed and rusted out. Plus they had some red wire running across the engine bay and through the firewall. I have yet to trace that to see where it goes. I removed all that crappy wiring job and rewired them to the stock wiring using solder and heat shrink so I know the connection is solid.

 

Perhaps whoever did that to my car did it because they couldn't figure out why it was doing this with the high beams? I never had a problem with them before I rewired them. They're brand new bulbs too.

 

Any ideas for where to start?

I'd start at the relays and see if your getting the signal from the stalk telling the relays the high beams should be on.

 

By the way, what model & year?

clean your grounds, and i would suspect the relays.
