So I have no low beams on either side. I have high beams and fog lights on both sides that work fine. The switch is working, 12V for the low beam position. I pulled the DRL (173) relay and same symptoms. I don't know what relay is for the headlights, or if that would matter since the high beams are working. There isn't power to the headlight bulb socket. All the wires seem fine that are visible. I reset the sockets that I could get to that may be causing a bad connection and everything seemed fine. I'm out of ideas. Any other ideas? It is a 2000 1.8T manual. Thanks alot for your help.
