The windshield wiper/washer system consists of the following components:

    • A permanent-magnet depressed-park wiper motor
    • A transmission assembly
    • Wiper arm and blade assemblies
    • A washer pump mounted on a washer solvent container
    • A wiper/washer switch

Based on the type of wiper/washer switch assembly used and the type of printed circuit board in the wiper motor cover, the system may serve as either a pulse (delay) type or a standard type windshield wiper.
