My 1989 Mk2 Jetta has just started developing electrical gremlins. All the wiper switch functions the Heated Rear Window and Heater blower (all Positions have stopped). The heater blower rheostat and motor were changed 2 years ago. They heve worked faultlessly until now. All the fuses are intact and each of the problem circuits are fused separately. The Golf used to have some problems with the fusebox.
Is this likely to be the same?
If so. Can the fusebox be repaired?
