REAR





An electrically operated fixed interval intermittent rear wiper and washer system is standard factory-installed equipment on this vehicle. The rear wiper and washer system includes the following major components, which are described in further detail elsewhere in this service information:

- ElectroMechanical Instrument Cluster - The ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) is located on the instrument panel directly in front of the driver. Instrument Cluster - Description.
- Rear Washer Nozzle (4) - The fluidic rear washer nozzle is integrated into the rear spoiler on the liftgate outer panel above the liftgate glass and is located to the right of the Center High-Mounted Stop Lamp (CHMSL).
- Rear Washer Plumbing - The plumbing for the rear washer system consists of rubber hoses, molded plastic fittings and a rear washer system check valve. The plumbing is routed along the right side of the engine compartment from the washer reservoir, through the dash into the passenger compartment, up the right cowl side and A-pillar to the headliner then through the upper liftgate opening header and the upper liftgate to the rear washer nozzle on the upper liftgate spoiler. The rear washer system check valve (3) connects the headliner washer hose to the liftgate washer hose and is located near the upper liftgate opening header behind the right upper D-pillar trim.
- Rear Wiper Arm And Blade (5) - The single rear wiper arm is secured by a nut directly to the rear wiper motor output shaft, which extends through a rubber grommet inserted into a hole in the center at the base of the liftgate glass. The rear wiper blade is secured to the rear wiper arm with an integral latch, and is parked near the base of the glass when the rear wiper system is not in operation.
- Rear Wiper Motor (6) - The rear wiper motor includes the motor bracket 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 on the inside of the liftgate beneath the liftgate glass opening.
- Right Multi-Function Switch (2) - The right (wiper) multi-function switch and the left (lighting) multi-function switch are secured to brackets integral to the clockspring housing, on the top of the steering column just below the steering wheel. The right multi-function switch is connected by a short jumper harness to the Steering Control Module (SCM), which is internal to the left multi-function switch housing. 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 multi-function switch is dedicated to providing all of the driver controls for both the front and rear wiper and washer systems.
- Steering Control Module - The Steering Control Module (SCM) is internal to the left multi-function switch housing, which is secured to a bracket integral to the left side of the clockspring housing on the top of the steering column just below the steering wheel. Only the left switch control stalk extending from the left side of the steering column is visible, while the remainder of the switch housing containing the SCM is concealed beneath the steering column shrouds. Steering Column Module - Description.
- Totally Integrated Power Module (1) - The Totally Integrated Power Module (TIPM) is located in the engine compartment, near the battery. Totally Integrated Power Module (TIPM) - Description.
- Washer Reservoir - The rear washer system shares a single reservoir and reversible pump with the front washer system, but has its own dedicated plumbing. The washer reservoir is located in the engine compartment ahead of the right front strut tower and 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, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.
