Washer Pump

The washer pump is controlled by the windshield wiper motor. The front and rear washer system share the same washer reservoir and a bi-directional washer pump. The pump delivers washer fluid to the windshield when the windshield wiper motor activates the internal washer relay, which provides voltage to the washer pump. Ground for the washer pump is provided through the rear washer relay located in the BJB. When activated, the washer pump delivers washer fluid to the windshield.

When the windshield wiper motor energizes the rear washer relay, the rear wiper relay provides voltage to the washer pump. Ground for the washer pump is provided through the washer relay internal to the windshield wiper motor. When activated, the pump delivers washer fluid to the rear window.
