For 1990-2009 cars

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

Pulse and timing functions, along with the demand wash function, are controlled by a printed circuit board in the wiper cover assembly. The wiper motor assembly is equipped with RFI (radio frequency interference) suppression.
