I have a 93 civic coupe and I cant figure out why my driver side headlight is dim and the other headlight lights up fine. Im thinking it might be the ground but idk where they all are located any suggestions???

 

Have you thought about replaceing the light bulbs?

 

yea i did that, i think the problem is its not getting a good ground but idk where all the grounds are located?

 

the ground is a yellow dimmed old looking box plastic that is screw into the engine bay. it has black wires only!!! mostly about 2 feet from the headlight. i had that problem and i had replaced the main harness thinking it was that. then i replaced the turn signal arm thinking it was it but then turns out it was a damn ground. take off the ground and get a flat head screwdriver rub it hard against the engine bay where it gets bolted on then do the same to it. if the light still dimmed out then i suggest bolting up the ground fuse to another hole location in the engine bay.
