Windshield Washer Motor: Description and Operation
Fig. 11 Washer Pump/Motor
WASHER PUMP/MOTOR
The washer pump/motor unit on the outboard side of the washer reservoir, near the bottom in the left front corner of the engine compartment. A
small permanently lubricated and sealed electric motor is coupled to the rotor-type washer pump. A seal flange with a large barbed inlet nipple on
the pump housing passes through a rubber grommet seal installed in the dedicated mounting hole near the bottom of the washer reservoir. A
smaller barbed outlet nipple on the pump housing connects the unit to the washer hose. The washer pump/motor unit is retained on the reservoir by
the interference fit between the barbed pump inlet nipple and the grommet seal, which is a light press fit. An integral electrical connector
receptacle is located on the motor housing. The washer pump/motor unit cannot be repaired. If faulty or damaged, the entire washer pump/motor
unit must be replaced.
The two washer nozzles are designed to dispense washer fluid into the wiper pattern area on the outside of the windshield glass. Pressurized
washer fluid is fed to each nozzle from the washer reservoir by the washer pump/motor through rubber hoses, which are attached to a barbed
nipple on each washer nozzle below the hood panel. The washer nozzles incorporate a fluidic design, which causes the nozzle to emit the
pressurized washer fluid as an oscillating stream to more effectively cover a larger area of the glass area to be cleaned.
