I had a 02 TDI Golf GLS come in the other day with the window switch lights flashing while the car was running. The hvac control lights had apparently gone out after having flashed in a similar manner for about 2 months. Before I start pulling my hair out chasing alt back ripples through a bcm, anyone ever seen/ heard of this problem? Any help is a greatly appreciated, as I am just learning the querks of these cars.
