You can check the 30 amp fuse under the rear seat fuse # 3 LMG (lift gate module) I just diagnosed mine as a faulty wiper motor. I decided to remove it and see if i could repair the motor and i heard a clinking noise coming from the white circuit box attached to the motor, removed the cover and found a resistor that had fallen off of the circuit board. soldered back in place and the wiper works great now, saved myself $200

Check the wiper relay. If it is good, then either the wiper motor or the wiper switch is bad. If it just stopped working one day for no reason, I would suspect the wiper motor. However,I just had this problem and it was the windshield wiper transmission, they started getting slower and slower over a few months and then it was seized one day. That is one strong motor VW uses so it is hard to go bad.
