97 a4 2.8
My drivers side headlight is VERY dim (other side is fine). When I kick on the high beams the light goes out completely. I replaced with new bulb (H7) and it is still the same. Any suggestions???????????????? Ground??? Fuse??? Bad harness?? Relay??

Thanks

 

Try swapping left and right parts, and see if the problem moves.

 

I get it back on thurs. I'll try it then. But exactly what parts are you taking about??

 

Relays.

 

Does it work now?
