Why wont my rear wiper work? Admittedly ever since i have owned the car, the rear wiper has never worked. Is there a fix to this, is it a common issue with the A3? Maybee its the fuse, where is the fuse boix located & which fuse is it i need to check? Sorry for all the questions, just now the bad weather has come im a bit stressed that i cant see out the back window!
