Yes, adrians_S13. You and vancouverbc are there ahead of me.
I am adding to the thread that you can be 95% assured it is the light switch when you don't see the high beam indicator light come on when the passenger headlight is dark and the driver headlight is high beam. Click teh high beam switch on and off and ... and if the blue light doesn't flash on and off with the high beam switch, it is the classic light switch problem.
Also, I am adding that you don't need to replace the entire light switch, just the small mechanical box at the base of the light switch.
Funny. My other car is a VW camper bus, and one of my low beams would not come on. I pulled both headlights and measured the voltage to the base of both of the seal beamed lights. One was getting 12.x volts, the other less than 4 volts.
The fuse was obviously not broken, or I would not be getting even 4 volts to the dark low beam light .
OK, I pulled the fuse and visually inspected it, and it was the fuse!! The VW uses a ceramic fuse, and somehow one end of the fuse MELTED enough that the fuse was not seated in the fuse box solid enough. replace the fuse with a clean one, and all is now good. A mechanical problem manifasted itself in electrical malfunction.
