Question, does both switches drivers and the one on affected door do the exact same thing. If so then the master switch may be your problem. If it was the regulator then the window would not move at all in normal situations. Or there would be some crunching or grinding noises coming from the window. The VW window regulators are a good design unlike the American vehicle manufactures designs of old. Any way feel free to ask questions. Jayfroelich@gmail.com
