Windshield Washer Motor: Description and Operation
WASHER PUMP/MOTOR
The washer pump/motor unit is located on the outboard side of the washer reservoir; near the bottom in the right 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 washer pump/motor unit is connected to the vehicle electrical system through a single take out and two-cavity connector of the headlamp and
dash wire harness. The washer pump/motor is grounded at all times through a take out of the headlamp and dash wire harness with a single eyelet
terminal connector that is secured by a nut to a ground stud located on the right front fender inner shield in the engine compartment. The washer
pump/motor receives battery current on a front washer pump/motor control circuit through an output of the Central Timer Module (CTM)
whenever the CTM receives an input through the closed contacts of the momentary washer switch within the multi-function switch. Washer fluid is
gravity-fed from the washer reservoir to the inlet side of the washer pump. When the pump motor is energized, the rotor-type pump pressurizes the
washer fluid and forces it through the pump outlet nipple, the washer plumbing, and the washer nozzles onto the windshield glass.
