Description And Operation: Description
The washer pump/motor (1) unit is located on a sump area near the bottom of the front side of the washer reservoir, which is located between the right front fender and the fender inner shield ahead of the right front wheel and the front wheel house splash shield. A small permanently lubricated and sealed electric motor is coupled to the rotor-type washer pump. On vehicles equipped with the (optional in some markets) rear washer system the electric motor is reversible and an integral valve body 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 (5) on the pump housing passes through a rubber grommet seal/filter screen (4) 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 black barbed outlet nipple (6) on the pump valve body housing connects the unit to the front washer plumbing, and, if equipped, the white barbed outlet nipple (3) connects the unit to the rear washer plumbing.
The washer pump/motor unit is retained on the reservoir by the interference fit between the pump inlet nipple and the grommet seal, which is a light press fit. This fit allows for mounting of the washer pump without the use of fasteners. An integral connector receptacle (2) on the top of the motor housing connects the unit to the vehicle electrical system through a dedicated take out and connector of the engine compartment wire harness.
The washer pump/motor unit cannot be repaired. If ineffective or damaged, the entire washer pump/motor unit must be replaced. The rubber grommet seal/filter screen is available for separate service replacement.
