The windshield wipers can be operated with the windshield wiper switch when the ignition switch is in the RUN or ACCESSORY positions. The windshield wiper system is protected by a 30 amp fuse (9) located in the Power Distribution Center (PDC) part of the Integrated Power Module (IPM) in the engine compartment. The wiper/washer switch is integral to the multi-function switch. It is a resistive MUX switch that sends inputs to the BCM to operate the wiper/washer system.

The windshield washer circuit is protected by a 15 amp Cartridge Fuse located in the IPM. The wiper motor has permanent magnetic fields. The speeds are determined by current flow to the appropriate set of brushes inside the motor. The current flow is controlled by the multi-function switch. The high speed/ low speed relays are located in the IPM. The speed sensitive intermittent wiper is controlled by the Body Control Module (BCM). The intermittent mode, with the vehicle traveling greater than 10.4 mph, has a range of 0.5 to 18 seconds. With the vehicle traveling less than 10.4 mph, the time delay doubles to a range of 1 to 36 seconds. The wiper arms will park at the base of the windshield just above the cowl cover after the wiper switch is turned OFF.

The windshield wiper motor and linkage is located in an integral wiper unit at the rear of the engine compartment. The wiper unit must be removed to gain access to the wiper motor.

The front and rear washer systems share the same washer pump motor.
