System Description

The windshield wiper/washer system consists of a permanent-magnet, depressed-park wiper motor assembly, a transmission assembly, wiper arm and blade assemblies, a washer pump mounted on a washer solvent container, and a wiper/washer switch assembly.

Pulse and timing functions, along with the demand wash function, are controlled by a printed circuit board in the wiper motor cover assembly. The wiper motor is also equipped with RFI (radio frequency interference) suppression.
Depressed-park positioning is accomplished by the crank arm on the wiper motor assembly.
