Windshield Washer Pump: Description and Operation
Windshield Washer Pump - Description
DESCRIPTION
The washer pump/motor unit is located on the rearward facing side of the washer reservoir, in the left front fender wheel house ahead of the front wheel
and the left front wheel house splash shield. A small permanently lubricated and sealed reversible electric motor (3) is coupled to the rotor-type washer
pump (4). The use of an integral valve body (7) allows the washer pump/motor unit to provide washer fluid to either the front or the rear washer systems,
depending upon the direction of the pump impeller rotation.
An inlet nipple (6) on the pump housing passes through a rubber grommet seal/filter screen installed in a dedicated mounting hole of the washer reservoir
sump. The filter screen prevents most debris from entering the pump housing. When the pump is installed in the reservoir the front barbed outlet nipple
(5) on the pump valve body housing connects the unit to the front washer hose, and the rear barbed outlet nipple (8) connects the unit to the rear washer
hose. The letters F and R molded into the valve body housing adjacent to each nipple provide further clarification of the nipple assignments.
The washer pump/motor unit is retained on the reservoir by the interference fit between the pump inlet nipple and the grommet seal, and by a snap post
(2) at the top of the pump motor housing that is engaged into a receptacle on the reservoir which is a light snap fit. An integral connector receptacle (1)
on the top of the motor housing connects the unit to the vehicle electrical system through a dedicated take out and connector of the headlamp and dash
wire harness.
The washer pump/motor unit cannot be repaired. If ineffective or damaged, the entire washer pump/motor unit must be replaced.
