Wiper Motor: Description and Operation
SYSTEM OPERATION
The two-speed permanent magnet wiper motor has an integral transmission and park switch. The motor also contains an internal automatic
resetting circuit breaker to protect the motor from overloads.
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 motor output shaft.
Wiper speed is controlled by current flow to the proper set of brushes. The wiper motor completes its wipe cycle when the windshield wiper switch
on the end of the multi-function switch stalk is turned to the Off position, and parks the blades in the lowest portion of the wipe pattern.
The windshield wiper linkage, pivots, bushings, mounting bracket, and motor are only serviced as a complete unit. If any part of this unit is faulty
or damaged, the entire wiper module must be replaced.
