I have a 2001 Audi A4 b5 and yesterday I fixed my right signal light and when I jumped in the car and tried to roll the windows down nothing happened? Sunroof opens and rear windows work just drivers and passengers windows are dead. Can not hear the window motor trying to work or anything. Just seems like no power getting to powered windows. Locks work , lights work just windows are not , if anyone can help me rigorous out it would be much appreciated!
