A couple weeks ago my passenger xenon went out in my 98 a4. I checked bulbs and they were fine so I bought a new ballast. It still doesn't work. I have tested the ballast and it works when directly connected to the battery. Any way to check my wiring to see if that is the problem? It is plugged into the harness and all connections look good. could it be a fuse issue? drivers side works fine.
any help or tips appreciated.
