Pump, Windshield Washer: Description: Headlamp
The headlamp washer pump/motor unit (1) of vehicles so equipped is located on the top of a sump area just above and outboard of the reversible front and rear washer pump on the rearward facing side of the washer reservoir, on the upper left corner of the cooling module in the engine compartment. A small permanently lubricated and sealed electric motor is coupled to the rotor-type washer pump.
An inlet nipple (4) on the bottom of the pump housing (3) passes through a rubber grommet seal/filter screen installed in a dedicated mounting hole of the washer reservoir. When the pump is installed in the reservoir the quick connect outlet nipple (5) on the pump housing points toward the left side of the vehicle and connects the unit to the headlamp washer plumbing.
The headlamp 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 Front End Module (FEM) wire harness.
The headlamp washer pump/motor unit cannot be repaired. If ineffective or damaged, the entire headlamp washer pump/motor unit must be replaced. The rubber grommet seal/filter screen is available for separate service replacement.
