my tipos wipers have decided to pack up. both the front and rear dont work the fuses are fine and the motors are good when rigged directly to a battery so i dont know what the problem is the washers work on the front and back but the wipers dont go with that either. i think i might be the stalk because the rear window heater buton on the end dosnt work either. if it is this where can i find a new one to replace it.
