System Description

The windshield wiper/washer system consists of a permanent-magnet, depressed-park, wiper motor assembly, wiper linkage assemblies, 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.
