Rear Wiper And Washer System
An electrically operated rear wiper and washer system is standard factory equipment on this vehicle. The rear wiper and washer system includes the following major components which are described in more detail elsewhere in this service information:
- Body Control Module - The Body Control Module (BCM) is located in the passenger compartment beneath the driver side end of the instrument panel. Refer to MODULE, BODY CONTROL (BCM), DESCRIPTION .
- Rear Washer Nozzle (3) - The rear washer nozzle and the integrated rear washer system check valve are located on the outer liftgate panel above the center of the liftgate glass opening.
- Rear Washer Plumbing - The plumbing for the rear washer system consists of rubber hoses and molded rubber or plastic fittings. The plumbing is routed along the right side of the engine compartment from the washer reservoir through the dash into the passenger compartment, along the left inner sill to the B-pillar, over the left rear inner wheel house to the top of the C-pillar, then through the left side upper liftgate opening header and the upper liftgate to the rear washer nozzle on the upper liftgate.
- Rear Wiper Arm and Blade (4) - The single rear wiper arm and blade assembly is secured by a nut directly to the rear wiper motor output shaft which extends through a rubber grommet inserted through a hole in the liftgate glass and is parked near the base of the liftgate glass when the rear wiper system is not in operation.
- Rear Wiper Motor (5) - The rear wiper motor includes the motor and three rubber-isolated wiper motor mounts. The wiper motor output shaft is the only visible component of the rear wiper motor. The remainder of the motor is concealed by the inner liftgate trim panel on the inside of the liftgate beneath the liftgate glass opening.
- Right Multifunction Switch (2) - The right (wiper) multifunction switch and the left (lighting) multifunction switch are integral to the clockspring and stalk unit on the top of the steering column just below the steering wheel. Only the switch control stalk extending from the right side of the steering column is visible, while the remainder of the switch is concealed beneath the steering column shrouds. The right multifunction switch is dedicated to providing all of the driver controls for both the front and rear wiper and washer systems.
- Washer Pump/Motor - The reversible electric washer pump/motor unit is located in a dedicated hole in a sump area on the lower, outboard surface of the washer reservoir, ahead of the right front wheel house. This single reversible washer pump/motor provides washer fluid to either the front or rear washer system plumbing, depending upon the direction of the pump motor rotation.
- Washer Reservoir (1) - The washer reservoir is located between the right front fender and the right inner fender shield, just ahead of the right front wheel house. The filler neck and cap are accessed from the right front corner of the engine compartment.
Hard wired circuitry connects the rear wiper and washer system components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the rear wiper and washer system components through the use of a combination of soldered splices, splice block connectors and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds. For proper wire repair, refer to STANDARD PROCEDURE . For connector repair procedures, refer to REMOVAL and INSTALLATION .
