Pump, Windshield Washer: Description
The washer pump/motor unit is located on the top of a sump area on the outboard 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 reversible electric motor is coupled to the rotor-type washer pump. The use of 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 (3) 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 black barbed outlet nipple (4) on the pump valve body housing connects the unit to the front washer plumbing, and the white barbed outlet nipple (2) 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 (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 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.
