2nd Gen Non-Engine/Transmission dim headlight

[Kalaehina]

My passenger side headlight went dim this morning. I have a summit wire harness and that's it as far as any tinkering I've done. Where should I begin my troubleshooting?

could just be corrosion on the contacts adding resistance. Same on high beam? Pull everything apart, clean get a electrical cleaner & grease, etc.

Chances are it's probably a poor ground if you are just 'dim' on one side. Check the local ground from the harness to the body/frame.

You can jumper from the questionable ground to a known good ground. That's for starters...

Got a good VOM? (Volt-Ohm Meter) They are cheap at Radio Shack along with a booklet on how to use it. Can't imagine having a modern car and not having one to check sensors and such...

thanks for the advice guys. This will be my weekend project.

First thing to check is the 15A fuse for right side. There is a fuse for each headlight. Been there, done that.

Thanks! I'll check that out too

high beams run thru a relay in the power dist. center under the hood. Also clean/check it.

Found out it was a loose ground tab on the bulb itself, I replaced the bulbs and everything is fine now.
