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 fluid reservoir, 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 also is equipped with RFI (radio frequency interference) suppression.

Depressed park positioning is accomplished by an external drive mechanism on the wiper motor assembly.
