Wiper Motor: Description and Operation
Front
SYSTEM DESCRIPTION
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
and is protected by a rubber boot. 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
stalk is moved to the Off position, and parks the blades in the lowest portion of the wipe pattern.
The windshield wiper motor cannot be repaired. If faulty or damaged, the entire wiper motor and boot assembly must be replaced. The wiper
linkage and pivots module, which includes the wiper motor, is also available for service.
