No Lo Beam, What Did I Do?
 
I had the dash down the other day. I now have parking lights, high beam, but no low beam. I am not good at using wire diagrams. All three wires are attached to the switch. Fuse #7 is good.

What about Fuse #8? Check that for the low beams. If fuses 7 and 8 are good, then it pretty much has to be either the dimmer relay, the dimmer switch, or a connection between them. Try wiggling the connections and plicking the relay with your finger while you simultaneously hit the dimmer switch with the car ON. If all of that fails, I would replace the dimmer relay with VW Part # 111 941 583.

I had this problem once when I pulled the dash and replaced it. I had pinched the wires and shorted out the circuit. The wires were pinched as they went around the heater.

You probably bumped the relay. Grab the wires on the relay and wiggle them around a little bit. Your low beams will likely come back. I have the same problem with mine. I should probably just replace the relay, as that would be easier than reaching under the dash when the lights go out, but that is down on the list. And besides, I drive in daylight most of the time anyway.:LOL:

I have low beams, fuses 7 and 8 are good. Also, I have a Triumph column. I'm sure I knocked something loose, I will crawl underneith tomorrow. :CRY::CRY::CRY:

OK, with the Triumph column there is no dimmer relay, so don't bother replacing it.;) Here's the wiring on it -- you must have pulled one slightly loose.

Best place I've found for replacing the headlight relay is airheads.com. I went through several relays before I bought one from airheads and then it finally worked correctly.

Mine went from high-beam, low-beam, NO-beam, completely unpredictably.

Patrickt, thank you. I must have missed this. I looked at the assy. manual, wiring diagram, connection diagram and adendums. PM me if you need to.


BTW my car is in the 100-334 car series, I don't know how applicable the above diagram is.

The earlier car is a little different, but the operative wires haven't changed color. The old white, red and blue wires (#9, 10, and 11) are connected to the U/W, N/R, and U/R Triumph wires respectively with bullet plugs.

Thank you as always, fixed.
