Wiper Motor: Description and Operation
SYSTEM OPERATION
The two-speed permanent magnet wiper motor has an integral transmission and park switch. The motor has a rubber-isolated mounting bracket
that is secured with bolts to a reinforcement with weld nuts on the engine side of the cowl plenum panel. The wiper motor output shaft passes
through the cowl plenum panel into the cowl plenum area, 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, the entire wiper motor assembly must be replaced. The wiper motor crank arm, mounting bracket,
and reinforcement are serviced separately.
