I've had my share of interesting issues on my Passat over the last decade, but this one takes the cake.
I was turning onto the highway yesterday, and used my turn signal to indicate the manuever. Next thing I know, the windshield wipers are on, and activating randomly. Doesn't seem to make any difference where I place the wiper activation stalk, save for the high position, which still seems to act in an appropriate manner. Also, the wiper activation seems to interrupt the speedo and tach signals every few cycles. Strange.
My guess was a flaky relay. I took the wiper relay out, opened her up, and carefully cleaned accumulated oxidation between the contacts by pulling a piece of paper between them while applying pressure. That seems to have helped, although not entirely cured the situation.
Would also like to try the same procedure with the turn signal relay, but where is the beast? Does anyone have a proper listing of the relay board for a B3 Passat? Inquiring minds would love to know where. Yes, I did spend about an hour with Google the other night and found some info on the Bentley forums, but there was some conflicting data.
Any other thoughts?
Thanks, David Glos
