The windshield wiper/washer system consists of a permanent-magnet, wiper motor, a transmission, wiper arm and blade assemblies, a washer pump and a solvent level sensor mounted on a washer solvent container, and a wiper/washer switch. Vehicles equipped with the Rainsense option are equipped with a Rainsense module as well as all of the components listed above. The outside moisture sensor is mounted ahead and to the right of the inside rear view mirror.

In addition to the features of a conventional (non-pulse) wiper system (mist, low, and high speeds), the pulse system includes an operating mode in which the wipers make single sweeps with an adjustable time interval between sweeps. The time interval is controlled by a solid-state timer in the wiper motor cover. The duration of the delay interval is determined by the delay resister in the wiper/washer switch.

The wiper motor is protected by a circuit breaker. If the wipers are blocked (by snow or ice, for example), the circuit breaker will open the circuit. The circuit breaker resets automatically when it cools. The wiper motor is equipped with RFI (radio frequency interference) suppression.

The Rainsense system includes the features of a conventional (non-Rainsense) wiper system (mist, low and high speeds). Additionally, the Rainsense system automatically operates when rain is sensed on the windshield and wiper/washer switch is in one of the AUTO DELAY positions.
