Rear Wiper/Washer System

The rear wiper and washer system includes the following major components, which are described in further detail elsewhere in this service information:

• Rear Washer Nozzle  - The fluidic rear washer nozzle is integral to the Center High-Mounted Stop Lamp (CHMSL) located on the liftgate outer panel above the liftgate flip-up glass. The rear washer nozzle includes an integral check valve.
• Rear Washer Plumbing  - The plumbing for the rear washer system consists of rubber hoses and molded plastic fittings. The plumbing is routed along the left side of the engine compartment from the washer reservoir, through the dash into the passenger compartment, up the left cowl side and 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 & Blade  - 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 flip-up glass. The rear wiper blade is secured to the rear wiper arm with an integral latch, and is parked off of the glass when the rear wiper system is not in operation.
• Rear Wiper Module  - The rear wiper module includes the module bracket, two rubber-isolated wiper module mounts and the rear wiper motor. The wiper motor output shaft is the only visible component of the rear wiper module. The remainder of the module is concealed within the liftgate.
• Right Multi-Function Switch  - The right (wiper) multi-function switch is secured to and directly connected to the Steering Control Module (SCM), on 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 multi-function switch is dedicated to providing all of the driver controls for both the front and rear wiper and washer systems (Refer to ELECTRICAL/WIPERS/WASHERS/RIGHT MULTI-FUNCTION SWITCH - DESCRIPTION) .
• Steering Control Module  - The Steering Control Module (SCM) is secured to the top of the steering column, just below the steering wheel and is completely concealed beneath the steering column shrouds. (Refer to STEERING/COLUMN/STEERING CONTROL MODULE - DESCRIPTION) .
• Totally Integrated Power Module  - The Totally Integrated Power Module (TIPM) is located 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 concealed between the left inner fender shield and the left outer fender panel, ahead of the left front wheel house splash shield. The filler neck and cap are the only visible components of the reservoir and, are accessed from the left front corner of the engine compartment.
