WASHER RESERVOIR
DESCRIPTION
A single washer fluid reservoir is used for both the
front and rear washer systems (Fig. 22). The molded
plastic washer fluid reservoir is mounted on the out-
board side of the right front frame rail in front of the
right front wheel, where it is concealed by the right
front wheel house splash shield. The only visible
component of the washer reservoir is the filler neck
and cap unit, which extends through a hole in the
right front wheel house extension panel into the
engine compartment. A bright yellow plastic filler cap
with an integral bail strap and filler neck mounting
bracket is labeled with an International Control and
Display Symbol icon for ªWindshield Washerº and the
text ªWasher Fluid Onlyº molded into it. The cap
snaps over the open end of the filler neck.
There is a dedicated hole on the outboard side of
the reservoir provided for the mounting of the
washer pump/motor unit, and another dedicated hole
on the rear of the reservoir for the washer fluid level
switch. A snap post receptacle molded into the reser-
voir allows for mounting of the washer pump without
the use of fasteners. The reservoir also features inte-
gral hose routing troughs on its outboard side and
integral routing clips along its top. The washer res-
ervoir is secured to the outboard side of the right
front frame rail by two screws and an integral
molded tab that engages in a slot in the right front
frame rail. Another screw secures the reservoir fillerneck to the upper radiator crossmember in the front
of the engine compartment. The right front fender
wheel house splash shield must be removed to access
the washer reservoir for service.
OPERATION
The washer fluid reservoir provides a secure,
on-vehicle storage location for a large reserve of
washer fluid for operation of the front and rear
washer systems. The washer reservoir filler neck pro-
vides a clearly marked and readily accessible point
from which to add washer fluid to the reservoir. The
washer/pump motor unit is located in a sump area
near the front of the reservoir to be certain that
washer fluid will be available to the pump as the
fluid level in the reservoir becomes depleted. The
washer pump/motor unit is mounted in the lowest
position in the sump. The washer fluid level switch is
mounted just above the sump area of the reservoir so
that there will be adequate warning to the vehicle
operator that the washer fluid level is low, before the
washer system will no longer operate.
REMOVAL
(1) Turn the front wheels full lock to the right.
(2) Unlatch and open the hood.
(3) Disconnect and isolate the battery negative
cable.
(4) Remove the air cleaner housing from the top of
the right front fender wheel house. (Refer to 9 -
ENGINE/AIR INTAKE SYSTEM/AIR CLEANER
ELEMENT - REMOVAL).
(5) Remove the screw that secures the washer res-
ervoir filler neck support to upper radiator cross-
member (Fig. 23).

DESCRIPTION
An electrically operated fixed interval intermittent
rear wiper and washer system is standard factory-in-
stalled equipment on this model (Fig. 1). The rear
wiper and washer system includes the following
major components, which are described in further
detail elsewhere in this service information:
²Multi-Function Switch- The multi-function
switch is located on the top of the steering column,
just below the steering wheel. The multi-function
switch includes a left (lighting) control stalk and a
right (wiper) control stalk. The right control stalk is
dedicated to providing all of the driver controls for
both the front and rear wiper systems. (Refer to 8 -
ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/
MULTI-FUNCTION SWITCH - DESCRIPTION).
²Rear Check Valve- The rear washer system
check valve is located in the washer plumbing
between the rear roof header and the roof outer
panel near the rear washer nozzle.
²Rear Washer Nozzle- The rear washer nozzle
is secured by a snap fit into a mounting hole in the
roof outer panel above the rear flip-up glass opening.²Rear Washer Plumbing- The plumbing for
the rear washer system consists of rubber hoses and
molded plastic fittings. The plumbing is routed along
the right side of the engine compartment from the
washer reservoir, through the dash into the passen-
ger compartment, up the right cowl side and A-pillar
to the headliner, and above the headliner to the rear
washer nozzle fitting within the rear roof header.
²Rear Wiper Arm- The single rear wiper arm is
secured by a nut directly to the rear wiper motor out-
put shaft, which extends through the center of the
tailgate outer panel near the base of the rear flip-up
glass.
²Rear Wiper Arm Park Ramp- The molded
rubber rear wiper arm park ramp is secured with a
screw to the tailgate outer panel to the right of the
rear wiper motor output shaft bezel. When the rear
wiper system is not in operation, the rear wiper arm
is parked off of the rear flip-up glass on this ramp so
that it will not interfere with or be damaged by the
flip-up glass operation.
²Rear Wiper Blade- The single rear wiper
blade is secured to the rear wiper arm with an inte-
gral latch, and is parked off of the rear flip-up glass
when the rear wiper system is not in operation.

CLEANING - REAR WIPER & WASHER SYSTEM
REAR WIPER SYSTEM
The squeegee of a wiper blade exposed to the ele-
ments for a long time tends to lose its wiping effec-
tiveness. Periodic cleaning of the squeegee is
suggested to remove any deposits of salt or road film.
The wiper blade, arm, and rear flip-up glass should
only be cleaned using a sponge or soft cloth and
windshield washer fluid, a mild detergent, or a non-
abrasive cleaner. If the wiper blade continues to
leave streaks, smears, hazing, or beading on the
glass after thorough cleaning of the squeegees and
the glass, the entire wiper blade assembly must be
replaced.
CAUTION: Protect the rubber squeegee of the wiper
blade from any petroleum-based cleaners, solvents,
or contaminants. These products can rapidly deteri-
orate the rubber squeegee.
8R - 32 REAR WIPERS/WASHERSKJ
REAR WIPERS/WASHERS (Continued)

A wiper arm cannot be adjusted or repaired. If
damaged or faulty, the entire wiper arm unit must be
replaced.
OPERATION
The rear wiper arm is designed to mechanically
transmit the motion from the rear wiper motor out-
put shaft to the rear wiper blade. The wiper arm
must be properly indexed to the motor output shaft
in order to maintain the proper wiper blade travel on
the glass. The wiper arm support is designed to lift
and support the rear wiper arm and blade off of the
glass when the rear wiper blade is parked. This sup-
port and the park ramp on the tailgate outer panel
below the glass also provide an alignment reference
to ensure accurate rear wiper arm and blade instal-
lation. The tapered hole in the wiper arm pivot end
is interlocks with the serrations on the outer circum-
ference of the tapered motor output shaft, allowing
positive engagement and finite adjustment of this
connection. A hex nut secures the wiper arm pivot
end to the threads on the rear wiper motor output
shaft and the pivot cover hinges and snaps over this
connection for a neat appearance. The spring-loaded
wiper arm hinge controls the down-force applied
through the tip of the wiper arm to the wiper blade
on the glass. The hook formation on the tip of the
wiper arm provides a cradle for securing and latching
the wiper blade pivot block to the wiper arm.
REMOVAL
(1) Lift the rear wiper arm pivot cover by lifting it
at the rear wiper motor output shaft end of the arm
(Fig. 9).
(2) Remove the nut that secures the rear wiper
arm to the rear wiper motor output shaft.
(3) If necessary, use a battery terminal puller to
disengage the wiper arm from the rear wiper motor
output shaft splines (Fig. 10).
NOTE: Depending upon the size and type of puller
used, it may be necessary to remove the spare tire
from the tailgate. Refer to the owner's manual in the
vehicle glove box for information on removing the
spare tire from the tailgate.
(4) Remove the rear wiper arm pivot end from the
motor output shaft.
INSTALLATION
NOTE: Always install the wiper arm and blade with
the wiper motor in the Park position.
(1) The rear wiper arm must be indexed to the
motor output shaft with the rear wiper motor in the
park position to be properly installed. Place thewiper arm onto the tailgate with the wiper arm sup-
port positioned on the park ramp and the tapered
mounting hole on the pivot end of the arm positioned
over the rear wiper motor output shaft.
(2) Position the tab on the back of the rear wiper
arm support on the tailgate park ramp in the Instal-
lation Position (Fig. 11).
(3) With the wiper arm in the Installation Posi-
tion, push the tapered mounting hole on the pivot
end of the wiper arm down over the rear wiper motor
output shaft.

(6) Press the pivot block latch release tab down-
ward until it snaps into its locked position over the
top of the wiper arm.
(7) Gently lower the wiper arm and place the arm
support in the tailgate park ramp.
REAR WIPER MOTOR
DESCRIPTION
The rear wiper motor is concealed within the tail-
gate, below the rear flip-up glass opening and behind
the tailgate inner trim panel. The end of the motor
output shaft that protrudes through the tailgate
outer panel to drive the rear wiper arm and blade is
the only visible component of the rear wiper motor
(Fig. 15). A rubber gasket, a bezel, and a nut secure
and seal the motor output shaft to the tailgate outer
panel. A molded plastic nut cover snaps onto the
bezel to conceal the nut and improve appearance. An
integral connector receptacle connects the rear wipermotor to the vehicle electrical system through a ded-
icated take out and connector of the tailgate wire
harness. The rear wiper motor consists of the follow-
ing major components:
²Bracket- The rear wiper motor bracket consists
of a stamped steel mounting plate for the wiper
motor that is secured with screws through two rub-
ber insulators to the tailgate inner panel.
²Rear Wiper Module- The rear wiper motor
electronic controls are concealed beneath a molded
plastic cover and includes the rear wiper system elec-
tronic logic and rear wiper motor electronic controls.
²Motor- The permanent magnet rear wiper
motor is secured with screws to the rear wiper motor
bracket. The wiper motor includes an integral trans-
mission, and the motor output shaft.
The rear wiper motor cannot be adjusted or
repaired. If any component of the motor is faulty or
damaged, the entire rear wiper motor unit must be
replaced. The motor output shaft gasket, bezel, nut,
and nut cover are available for service replacement.
OPERATION
The rear wiper motor receives non-switched bat-
tery current through a fuse in the Junction Block
(JB) on a fused B(+) circuit and is connected to
ground at all times. The rear wiper motor operation
is controlled by the vehicle operator through battery
current signal inputs received by the rear wiper
motor electronic control module from the rear wiper
switch circuitry that is integral to the right (wiper)
control stalk of the multi-function switch on the
steering column. The module also receives an exter-
nal control input from the flip-up glass ajar switch
sense circuit. If the rear wiper module senses that
the flip-up glass is ajar, it will not allow the rear
wiper motor to operate.
The rear wiper module electronic control logic uses
these inputs, its internal inputs, and its program-
ming to provide a continuous wipe mode, an inter-
mittent wipe mode, a wipe-after-wash mode, and off-
the-glass wiper blade parking. The wiper blade
cycling is controlled by the internal electronic con-
trols of the module. The module controls current flow
to the wiper motor brushes and provides an elec-
tronic speed control that speeds the wiper blade near
the center of the glass, but slows the wiper blade
during directional reversals at each end of the wipe
pattern and during wiper blade off-the-glass parking
for quieter operation. The wiper motor transmission
converts the rotary output of the wiper motor to the
back and forth wiping motion of the rear wiper arm
and blade on the rear flip-up glass.
