Check Valve, Washer: Description: Rear
The rear check valve (2) is located in the hardtop disconnect plate (1) located in the left inner D-pillar (3) of the removable hardtop. The disconnect plate provides a washer plumbing interconnect between the rear washer hose (4) contained within the body wire harness and the hardtop washer hose connected to the rear wiper motor. The disconnect plate also provides an electrical interconnect between the body wire harness and the hardtop wiring connected to the rear wiper motor.
The check valve consists of a molded white plastic valve body with a raised center flange and two raised wedge locks that secure the unit in the disconnect plate. A barbed outlet hose nipple is formed on the side of the valve body oriented toward the rear washer nozzle, and a straight inlet hose nipple is formed on the side of the valve body oriented toward the washer pump. Within the check valve body, a small check ball is held against an integral valve seat by a small coiled spring.
The rear check valve cannot be adjusted or repaired and, if ineffective or damaged, it must be replaced.
