The windshield wiper/washer system consists of a wiper motor, a wiper transmission, wiper arm and blade assemblies, a washer solvent pump mounted on the side of a washer solvent container, and a turn signal-type wiper/washer switch.

The permanent magnet, positive park wiper motor is mounted on the engine side of the cowl. The wiper motor is equipped with the radio frequency interface (RFI) suppression. The wiper motor module and the cover are the only replaceable parts of the wiper motor.

The wiper/washer system has high, low, mist, delay (pulse), and wash modes. The wiper motor and the washer solvent pump can only be operated when the ignition switch is in the RUN or ACCESSORY position.
