Recently I was hit on the rt. front side. All repairs have been done, by myself. The bulbs in the unit are good but the unit (main bulb) just won't light up. At first, I could wiggle the harness and it would light up. But now, nothing.. Any suggestions

Repairs were:
Steering Box, Radius Arm, All Mounts (mtr & trns), and of course Headlight.

 

Chop chop, wire new plug.


Or take advantage of this and swap to HID's.

 

Won't work on high or low beams??????????
I would suggest you swap your other light bulb over to the bad side, probably just have brokem elements.

 

Works on High Beam, but nothing now. It's like a dead duck in the water. But when I plug the (drvrs) opposite unit onto the right, nothing. When I plug the (pass) NonWrking unit onto the drivers harness, works great. Any Suggestions?

 

Sounds like you need a new wire harness.
