Grand Cherokee 2WD L6-4.0L VIN S (1997)
Wiper Motor: Description and Operation
Front
The two-speed permanent magnet wiper motor has an integral transmission and park switch. The motor is secured to the wiper linkage and pivot
module bracket with three screws. The wiper motor output shaft passes through a hole in the module bracket, where a nut secures the wiper motor
crank arm to the output shaft.
Wiper speed is controlled by current flow to the appropriate set of brushes. The wiper motor completes its wipe cycle when the wiper/washer
(multi- function) switch is turned to the Off position, and parks the blades in the lowest portion of the wipe pattern.
The wiper motor cannot be repaired. If faulty or damaged, the entire wiper motor assembly must be replaced. The motor crank arm and the linkage
and pivots module are available for service.
