Wiper/Washer Systems: Description
The internal components of the "J" Body wiper system include a field magnet, armature, drive gear, park switch actuator, brush holder assembly and a radio noise suppression capacitor. All of these components are enclosed in a die-cast aluminum housing with a plastic cover. A ground strap is connected to one of the motor mounting bolt holes to provide a ground for the capacitor. The motor is protected by an automatic reset type circuit breaker located on the motor brush holder assembly. The motor has a 4-terminal connector.
The washer pump consists of permanent magnet motor and pump assembly. The washer pump assembly is mounted in the bottom of the solution jar by a nut located inside the solution jar. The washer pump can only be operated with the ignition switch in the "RUN" or "ACCESSORY" position.
