Rear Wipers/Washers: Description: Notes
An electrically operated fixed speed rear wiper and washer system is optional factory-installed equipment on this model when it is also equipped with the optional hardtop roof. The rear wiper and washer system includes the following major components, which are described in further detail elsewhere in this service information:
- Rear Check Valve - The rear washer system check valve is located near the belt line in the left rear corner of the passenger compartment in the vehicle. The rear check valve also serves as the inline connector between the body wire harness half and the hardtop wire harness half of the rear washer hose plumbing.
- Rear Washer Nozzle - The rear washer nozzle is located in a mounting hole in the rear liftglass just below and inboard of the rear wiper motor output shaft. A plastic nut secures the threaded nipple on the back of the nozzle to the inside of the liftglass.
- 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 vehicle with the body wire harness from the washer reservoir in the engine compartment, through the dash into the passenger compartment, and back to the left rear corner of the body. The rear check valve splices the body wire harness half of the washer hose to the hardtop wire harness half of the hose at the left rear corner of the body. The hardtop wire harness and washer hose are routed up the left rear corner of the hardtop and over the upper liftglass opening header to the rear washer nozzle in the upper right corner of the rear liftglass. A molded plastic washer hose cap is secured by an integral bail strap to the body wire harness half of the rear washer hose near the left rear corner of the body. This cap serves to plug the rear washer hose when the hardtop is removed from the vehicle.
- Rear Washer Pump/Motor - The rear washer pump/motor unit is located in a dedicated hole on the lower inboard side of the washer reservoir, on the top of the left front fender wheel house in the engine compartment. The optional rear washer pump is located just behind and above the standard front washer pump/motor unit on the reservoir.
- Rear Wiper and Washer Switch - The rear wiper and washer switch is located in the accessory switch bezel near the bottom of the center stack area on the instrument panel. Only the switch rocker button is visible through the lower opening of the instrument panel center bezel, the remainder of the switch is concealed behind the accessory switch bezel within the instrument panel. The rear wiper and washer switch is dedicated to providing all of the driver controls for both the rear wiper and the rear washer systems.
- Rear Wiper Arm - The single rear wiper arm is secured by a nut directly to the rear wiper motor out-put shaft, which extends through a mounting hole in the liftglass inboard of the upper right liftglass hinge.
- Rear Wiper Blade - The single rear wiper blade is secured to the rear wiper arm with an integral latch, and is parked in a horizontal position near the top of the liftglass when the rear wiper system is not in operation.
- Rear Wiper Motor - The rear wiper motor out-put shaft is the only visible component of the rear wiper motor. The remainder of the motor is concealed behind a plastic trim cover on the inside of the liftglass near the upper right liftglass hinge. The rear wiper motor includes the motor bracket, the rear wiper motor, an internal automatic resetting circuit breaker, a diode, and the rear wiper motor park switch.
- Washer Reservoir - The rear washer system shares a single reservoir with the front washer system, but has its own dedicated washer pump/motor unit and unique plumbing provisions. The reservoir is secured to the top of the left front fender wheel house within the engine compartment of the vehicle.
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.
