Washer Pump

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

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