REAR WIPERS/WASHERS

REAR WIPERS/WASHERS (Continued)
• 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 lift-
glass 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 sys-
tem, 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 com-
bination 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.
OPERATING MODES
The components of the rear wiper and washer sys-
tem are designed to work in concert to provide the
following operating modes:
• Continuous Wipe Mode - When the rear wiper
and washer switch rocker is moved to the Wipe posi-
tion, the rear wiper will be operated in a continuous
manner at a fixed wipe cycle speed until the switch
is moved to the Off position. When the Off position is
selected, the rear wiper motor will continue to oper-
ate until the current wipe cycle is complete, then
park the wiper blade in a horizontal position near
the top of the liftglass.
• Washer Mode - The rear wiper and washer
switch rocker must first be moved to the Wipe detent
in order to access the momentary Wash position and
operate the rear washer system. When the Wash
position is selected, the rear washer system will dis-
pense washer fluid onto the liftglass and the rear
wiper motor will operate in a continuous mode for as
long as the switch is held closed. The rear wiper and
washer switch rocker must be manually moved back
to the Off position following rear washer operation in
order to turn the rear wiper system off.

OPERATION

The rear wiper and washer system is designed to
provide the vehicle operator with a convenient, safe,
and reliable means of maintaining visibility through
the rear liftglass. The various components of this sys-
tem are designed to convert electrical energy pro-
duced by the vehicle electrical system into the
mechanical action of the wiper blade to wipe the out-
side surface of the glass, as well as into the hydraulic
action of the washer system to apply washer fluid
stored in an on-board reservoir to the area of the
glass to be wiped. When combined, these components
provide the means to effectively maintain clear visi-
bility for the vehicle operator by removing excess
accumulations of rain, snow, bugs, mud, or other
minor debris that might be encountered while driv-
ing the vehicle under numerous types of inclement
operating conditions from the outside of the liftglass
surface.
The vehicle operator initiates all rear wiper and
washer system functions with the rear wiper and
washer switch located in the accessory switch bezel,
just below the heater and air conditioner controls in
the center stack area of the instrument panel. Mov-
ing the switch rocker downward to a detent position
selects the rear wiper system fixed cycle operating
mode. Moving the switch rocker downward past the
wipe mode detent actuates the momentary rear
washer system switch.
The rear wiper and washer system will only oper-
ate when the ignition switch is in the On position.
When the ignition switch is in the On position, bat-
tery current is directed from a fuse in the Power Dis-
tribution Center (PDC) to the rear wiper and washer
system fuse in the fuse block. This fuse provides bat-
tery current through a fused ignition switch output
(run) circuit to the rear wiper and washer switch,
and to one fixed contact of the rear wiper motor park
switch.
The hard wired circuits and components of the rear
wiper and washer system may be diagnosed and
tested using conventional diagnostic tools and proce-
dures.

operation of each of the rear wiper and washer sys-
tem operating modes.
