Windshield Wiper/Washer System

The windshield wiper/washer system consists of a permanent magnet, positive-park wiper motor assembly, a transmission assembly, wiper arm and blade assemblies, a washer pump mounted on the side of a washer solvent container, and a turn signal- type wiper/washer switch assembly with detents. The die-cast aluminum housing of the wiper motor provides cooling for interior parts. The wiper motor is equipped with RFI (radio frequency interference) suppression.

The wiper motor drives a crank arm that attaches to individual transmission links for both the right and left sides. The transmission links are mounted in front of the windshield inside the fresh air plenum. The transmission transfers rotary motion from the wiper motor into reciprocating motion at the transmission drive shafts.

The wiper motor assembly includes a DELAY (pulse) mode in addition to the three modes of a standard system - HI, LO, and MIST.
A circuit board assembly in the wiper motor assembly and a variable resistor (rheostat) in the turn signal-wiper/washer switch control the rate of pulse to the wiper motor.

The wiper motor is sealed. No service parts are available. The motor must be replaced and not repaired if service is required.

The delay module is also sealed and attached directly to the wiper motor. It also is replaced as a unit during service.
