REAR





An electrically operated 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) is also known as the Cab Compartment Node (CCN) in this vehicle. The EMIC/CCN is located in the instrument panel above the steering column opening, directly in front of the driver.
- Front Control Module - The Front Control Module (FCM) is integral to the Integrated Power Module (IPM). The FCM/IPM is located in the engine compartment, near the battery and the Power Distribution Center (PDC).
- Heater-Air Conditioner Control (1) - The vehicle operator controls all rear wiper and washer system functions through two switches that are operated by a single rotary control knob in the heater-air conditioner control located in the center stack area of the instrument panel. The heater-air conditioner control sends electronic rear wiper and rear washer switch status messages to the EMIC over the Controller Area Network (CAN) data bus.
- Rear Washer Nozzle (2) - A fluidic rear washer nozzle is secured by latch features to a mounting hole in the liftgate header panel to the right of the Center High-Mounted Stop Lamp (CHMSL) above the liftgate glass.
- Rear Washer Plumbing - The plumbing for the washer system consists of rubber hoses and molded plastic fittings. The plumbing is routed along the underside of the Power Distribution Center (PDC) bracket to the engine compartment from the washer reservoir. The rear washer hose is routed through the dash panel from the engine compartment into the passenger compartment, up the left A-pillar where it is connected to a hose integral to the headliner that runs from the A-pillar to the rear washer nozzle on the upper liftgate header.
- Rear Wiper Arm - The single rear wiper arm is secured by a nut directly to the rear wiper motor output shaft, which extends through the center of the liftgate outer panel near the base of the liftgate glass.
- Rear Wiper Blade - The single rear wiper blade is secured to the rear wiper arm with an integral latch, and is parked near the bottom of the liftgate glass when the rear wiper system is not in operation.
- Rear Wiper Motor (3) - The rear wiper motor includes the motor bracket, the rear wiper motor, the rear wiper bezel and grommet shaft seal and the rear wiper motor park switch. The wiper motor output shaft and bezel are the only visible component of the rear wiper motor. The remainder of the motor is concealed within the liftgate beneath the liftgate glass opening.
- Rear Wiper Relay - The rear wiper relay is an International Standards Organization (ISO) micro relay that is located in the Power Distribution Center (PDC) in the engine compartment near the battery.
- 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 integral to the engine coolant reserve bottle located in the left 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.
