Hello, I have a 91 Silverado the right side headlights don’t work(bright or dim) this makes me think that maybe it’s not just the bulbs. Is there anything I should be checking out are the right and left lights on different fuses? Thanks

 

They're not going to be on a different fuse. Right side is the side that catches the water from the road. I'd suggest as a starter to remove, clean the electrical connection.
