Windshield Washer Pump: Description and Operation
Description
DESCRIPTION
The washer pump/motor unit (1) is located on the top of a sump area on the outward facing side of the combination washer reservoir/coolant reserve
bottle, ahead of the right front fender wheel house splash shield. A small permanently lubricated and sealed electric motor is coupled to the rotor-type
washer pump (3).
An inlet nipple (5) on the bottom of the pump housing passes through a rubber grommet seal (4) installed in a dedicated mounting hole of the washer
reservoir. When the pump is installed in the reservoir the barbed outlet nipple (6) on the pump valve body housing points rearward and connects the unit
to the reservoir washer hose, which is engaged in an integral trough molded into the reservoir/bottle unit.
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. The top of the washer pump is also secured to the washer reservoir by a light snap fit into a receptacle molded into the reservoir that 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 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.
