Windshield Washer Pump: Description and Operation
SYSTEM OPERATION
The washer pumps and motors are mounted near the bottom of their respective windshield or rear window washer reservoir. A barbed nipple on
the pump housing passes through a rubber grommet seal installed in a hole near the bottom of the reservoir. The washer pump is retained by an
interference fit between the barbed pump nipple and the grommet seal, which is a light press fit.
A permanently lubricated and sealed motor is coupled to a rotor-type pump. Washer fluid is gravity-fed from the reservoir to the pump. When the
motor is energized, the pump pressurizes the washer fluid and forces it through the plumbing to the nozzles.
The washer pump and motor units cannot be repaired. If faulty, the entire washer pump and motor unit must be replaced.
