so im putting my ef shell together and only my driver side head light works. i checked the fuse and they are fine. then i switched the bulbs and the driver side is the only one that works. what else could be the problem? maybe the plug that the bulb plugs into?. ket me know any ideas thanks

 

Well for tedious but effective trouble shooting you could go through and swap from the side that works to the side that doesn't. Just do one thing at a time, once it works, you know what would need replaced.

 

There is a ground wire that runs to the fender for each headlight make sure it is grounded. Ask me how I know.

 

is the ground connected to a little box type thing? or is just a wire?

 

It is connected to a relay ie the little box like thingy
