so i have a 94 gc and my headlights stopped working. I've checked all the fuses and relays,the bulbs,and swapped switches. Other than getting a donor harness does anybody have an idea where to check. The running lights and blinkers all work just no headlights. Any advice would be great. thanks

 

Check voltage at the headlight plugs, then back at the fuse box and so on and so forth until you find where the power stops, then you'll know what to fix.

 

It could be the multi-function switch.

 

mine acts same. when i flick headlights half way not full, it sometimes goes dark. it must be the combination switch/lever.

 

Check the ground wire.. it is for the headlights only and needs to be connected tightly.. I was haveing dim lights and after much scratching and --*&*((*(*&^& ing i found a ground that was just hanging.. tighted it up with a new bolt and happy days are here again..

 

which wire is this one? could you help me to locate?

 

It's the black wire on the back of the blue plugs on the backside of the headlight.
