Sport Wagon Rear Wiper/Wash System: Notes

The rear wiper/washer is a function of the ZKE system. The rear wiper motor and gear assembly is mounted in the tail gate through insulating bushing to prevent operation noises from being transmitted into the body's interior.

The wiper pivot bearing, wiper shaft and wiper arm are mounted on the rear window. A mechanical coupling is used to connect the two components as on the E39 wagon.
