Windshield Washer Pump: Description and Operation
SYSTEM OPERATION
The washer pumps and motors are mounted near the bottom of the washer reservoir. A threaded nipple on the pump housing passes through a
rubber grommet seal installed in a hole near the bottom of the reservoir. A plastic nut and washer secures the washer pump nipple from the inside
of the reservoir.
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 unit cannot be repaired. If faulty, the entire washer pump and motor unit must be replaced.
