WIPER HIGH/LOW RELAY
DESCRIPTION
The wiper high/low relay is located in the Power
Distribution Center (PDC) in the engine compart-
ment near the battery. The wiper high/low relay is a
conventional International Standards Organization
(ISO) micro relay (Fig. 25). Relays conforming to theISO specifications have common physical dimensions,
current capacities, terminal patterns, and terminal
functions. The relay is contained within a small, rect-
angular, molded plastic housing and is connected to
all of the required inputs and outputs by five integral
male spade-type terminals that extend from the bot-
tom of the relay base.
The wiper high/low relay cannot be adjusted or
repaired and, if faulty or damaged, the unit must be
replaced.
OPERATION
The wiper high/low relay is an electromechanical
switch that uses a low current input from the Body
Control Module (BCM) to control a high current out-
put to the front wiper motor. The movable common
feed contact point is held against the fixed normally
closed contact point by spring pressure. When the
relay coil is energized, an electromagnetic field is
produced by the coil windings. This electromagnetic
field draws the movable relay contact point away
from the fixed normally closed contact point, and
holds it against the fixed normally open contact
point. When the relay coil is de-energized, spring
pressure returns the movable contact point back
against the fixed normally closed contact point. A
resistor is connected in parallel with the relay coil in
the relay, and helps to dissipate voltage spikes and
electromagnetic interference that can be generated as
the electromagnetic field of the relay coil collapses.
The wiper high/low relay terminals are connected
to the vehicle electrical system through a connector
receptacle in the Power Distribution Center (PDC).
The inputs and outputs of the wiper high/low relay
include:
²Common Feed Terminal- The common feed
terminal (30) is connected to the output of the wiper
on/off relay at all times through the wiper on/off
relay output circuit.
²Coil Ground Terminal- The coil ground termi-
nal (85) is connected to a control output of the Body
Control Module (BCM) through a front wiper high/
low relay control circuit. The BCM controls front
wiper motor operation by controlling a ground path
through this circuit.
²Coil Battery Terminal- The coil battery ter-
minal (86) receives battery current at all times from
a circuit breaker in the Junction Block (JB) through
a fused ignition switch output (run-acc) circuit.
²Normally Open Terminal- The normally open
terminal (87) is connected to the high speed brush of
the front wiper motor through a front wiper high/low
relay high speed output circuit, and is connected to
the high speed brush whenever the relay is ener-
gized.

²Rear Wiper Module- The rear wiper motor
output shaft is the only visible component of the rear
wiper module. The remainder of the module is con-
cealed within the tailgate below the rear flip-up glass
opening. The rear wiper module includes the module
bracket, the rear wiper motor, and the rear wiper
electronic control circuitry.
²Washer Pump/Motor- The reversible electric
washer pump/motor unit is located in a dedicated
hole on the lower outboard side of the washer reser-
voir, behind the right front wheel house splash
shield. This single reversible washer pump/motor
provides washer fluid to either the front or rear
washer system plumbing, depending upon the direc-
tion of the pump motor rotation. (Refer to 8 - ELEC-
TRICAL/FRONT WIPERS/WASHERS/WASHER
PUMP MOTOR - DESCRIPTION).
²Washer Reservoir- The washer reservoir is
concealed behind the right front wheel house splash
shield ahead of the right front wheel. The washer
reservoir filler neck is the only visible portion of the
reservoir, and it is accessed from the right front cor-
ner of the engine compartment. This single washer
reservoir is shared by both the front and rear washer
systems. (Refer to 8 - ELECTRICAL/FRONT WIP-
ERS/WASHERS/WASHER RESERVOIR - DESCRIP-
TION).
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 system are designed to work in
concert to provide the following operating modes:
²Continuous Wipe Mode- The control ring on
the right (wiper) control stalk of the multi-function
switch has an On position. When selected, this
switch position will cause the rear wiper motor to
operate in a continuous manner at a fixed wipe cycle
speed.
²Intermittent Wipe Mode- The control ring on
the right (wiper) control stalk of the multi-function
switch has a Delay position. When selected, thisswitch position will cause the rear wiper motor to
operate in an intermittent manner at a fixed interval
wipe cycle speed.
²Washer Mode- The control ring on the right
(wiper) control stalk of the multi-function switch has
two momentary Wash positions, one at the end of
each direction of control ring rotation. When the con-
trol ring is rotated to the downward (counterclock-
wise) Wash position, the rear washer system will
dispense washer fluid onto the flip-up glass and the
rear wiper motor will operate in a continuous mode
for as long as the switch is held closed, then provide
several additional wipe cycles after the washer
switch is released (wipe-after-wash mode). When the
control ring is rotated to the upward (clockwise)
Wash position, the rear washer system will dispense
washer fluid onto the flip-up glass and the rear wiper
motor will operate in a continuous mode for as long
as the switch is held closed, then return to fixed wipe
mode operation after the washer switch is released.
²Wipe-After-Wash Mode- The control ring on
the right (wiper) control stalk of the multi-function
switch has two momentary Wash positions, one at
the end of each direction of control ring rotation.
When the control ring is rotated to the downward
(counterclockwise) Wash position, the rear washer
system will dispense washer fluid onto the flip-up
glass and the rear wiper motor will operate in a con-
tinuous mode for as long as the switch is held closed,
then provide several additional wipe cycles after the
washer switch is released.
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 flip-up glass. The various components of this
system 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 from the swing gate flip up glass sur-
face that might be encountered while driving the
vehicle under numerous types of inclement operating
conditions.
The vehicle operator initiates all rear wiper and
washer system functions with the right (wiper) con-
trol stalk of the multi-function switch that extends
from the right side of the steering column, just below
the steering wheel. Rotating the control ring on the

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)

REAR WASHER SYSTEM
If the washer system is contaminated with foreign
material, drain the washer reservoir by removing the
washer pump/motor from the reservoir. Clean foreign
material from the inside of the washer pump/motor
inlet filter screen and the washer reservoir using
clean washer fluid, a mild detergent, or a non-abra-
sive cleaner. Flush foreign material from the washer
system plumbing by first disconnecting the washer
hose from the washer nozzle, then running the
washer pump/motor to run clean washer fluid or
water through the system. A plugged or restricted
washer nozzle should be carefully back-flushed using
compressed air. If the washer nozzle obstruction can-
not be cleared, replace the washer nozzle.
CAUTION: Never introduce petroleum-based clean-
ers, solvents, or contaminants into the washer sys-
tem. These products can rapidly deteriorate the
rubber seals and hoses of the washer system, as
well as the rubber squeegee of the wiper blade.
CAUTION: Never use compressed air to flush the
washer system plumbing. Compressed air pres-
sures are too great for the washer system plumbing
components and will result in further system dam-
age. Never use sharp instruments to clear a
plugged washer nozzle or damage to the nozzle ori-
fice and improper nozzle spray patterns will result.
INSPECTION - REAR WIPER & WASHER
SYSTEM
REAR WIPER SYSTEM
The rear wiper blade and wiper arm should be
inspected periodically, not just when wiper perfor-
mance problems are experienced. This inspection
should include the following points:
(1) Inspect the wiper arm for any indications of
damage, or contamination. If the wiper arm is con-
taminated with any foreign material, clean as
required. (Refer to 8 - ELECTRICAL/REAR WIPERS/
WASHERS - CLEANING). If a wiper arm is damaged
or corrosion is evident, replace the wiper arm with a
new unit. Do not attempt to repair a wiper arm that
is damaged or corroded.
(2) Carefully lift the wiper arm off of the park
ramp. Note the action of the wiper arm hinge. The
wiper arm should pivot freely at the hinge, but with
no lateral looseness evident. If there is any binding
evident in the wiper arm hinge, or there is evident
lateral play in the wiper arm hinge, replace the
wiper arm.CAUTION: Do not allow the wiper arm to spring
back against the glass without the wiper blade in
place or the glass may be damaged.
(3) Once proper hinge action of the wiper arm is
confirmed, check the hinge for proper spring tension.
The spring tension of the wiper arm should be suffi-
cient to cause the rubber squeegee to conform to the
curvature of the glass. Replace a wiper arm if it has
low or no spring tension.
(4) Inspect the wiper blade and squeegee for any
indications of damage, contamination, or rubber dete-
rioration (Fig. 2). If the wiper blade or squeegee is
contaminated with any foreign material, clean them
and the glass as required. (Refer to 8 - ELECTRI-
CAL/REAR WIPERS/WASHERS - CLEANING). If
after cleaning the wiper blade and the glass, the
wiper blade fails to clear the glass without smearing,
streaking, chattering, hazing, or beading, replace the
wiper blade. Also, if a wiper blade is damaged or if
the squeegee rubber is damaged or deteriorated,
replace the wiper blade with a new unit. Do not
attempt to repair a wiper blade that is damaged.

REAR WASHER SYSTEM
The washer system components should be
inspected periodically, not just when washer perfor-
mance problems are experienced. This inspection
should include the following points:
(1) Check for ice or other foreign material in the
washer reservoir. If contaminated, clean and flush
the washer system. (Refer to 8 - ELECTRICAL/
REAR WIPERS/WASHERS - CLEANING).
(2) Inspect the washer plumbing for pinched, leak-
ing, deteriorated, or incorrectly routed hoses and
damaged or disconnected hose fittings. Replace dam-
aged or deteriorated hoses and hose fittings. Leaking
washer hoses can sometimes be repaired by cutting
the hose at the leak and splicing it back together
using an in-line connector fitting. Similarly, sections
of deteriorated hose can be cut out and replaced by
splicing in new sections of hose using in-line connec-
tor fittings. Whenever routing a washer hose or a
wire harness containing a washer hose, it must be
routed away from hot, sharp, or moving parts. Also,
sharp bends that might pinch the washer hose must
be avoided.
REAR CHECK VALVE
DESCRIPTION
A rear washer system check valve is standard
equipment on this model (Fig. 3). The rear check
valve is located in the washer plumbing between the
rear roof header and the roof outer panel near the
rear washer nozzle. The rear check valve consists of
a molded plastic body with a round center sectionand barbed hose nipples at each end. An arrow for-
mation molded into the center section of the valve
body indicates the direction of flow through the
valve. The rear check valve cannot be adjusted or
repaired and, if faulty or damaged, it must be
replaced.
OPERATION
The rear check valve prevents washer fluid from
draining out of the rear washer supply hoses back to
the washer reservoir. This drain-back would result in
a lengthy delay from when the rear washer switch is
actuated until washer fluid was dispensed through
the rear washer nozzle, because the washer pump
would have to refill the rear washer plumbing from
the reservoir to the nozzle. The check valve also pre-
vents washer fluid from siphoning through the rear
washer nozzle after the rear washer system is turned
Off.
Within the check valve body, a small check valve is
held in place against a seat by a small coiled spring
to restrict flow through the unit until the valve is
unseated by a predetermined inlet fluid pressure.
When the washer pump pressurizes and pumps
washer fluid from the reservoir through the rear
washer plumbing, the fluid pressure overrides the
spring pressure applied to the check ball within the
valve and unseats the valve, allowing washer fluid to
flow toward the rear washer nozzle. When the
washer pump stops operating, spring pressure seats
the check valve and fluid flow in either direction
within the rear washer plumbing is prevented.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the Center High Mounted Stop Lamp
(CHMSL) unit from the rear of the roof panel. (Refer
to 8 - ELECTRICAL/LAMPS/LIGHTING - EXTERI-
OR/CENTER HIGH MOUNTED STOP LAMP UNIT
- REMOVAL).
WARNING: THE EDGES OF THE SHEET METAL
AROUND THE CENTER HIGH MOUNTED STOP
LAMP MOUNTING HOLE IN THE ROOF PANEL.
TAKE THE PROPER PRECAUTIONS TO AVOID PER-
SONAL INJURY.
(3) Reach through the CHMSL unit mounting hole
in the rear of the roof panel to access and disconnect
the rear washer hose at the barbed nipple of the rear
washer nozzle (Fig. 4).
(4) Pull the rear washer hose through the CHMSL
unit mounting hole far enough to access and discon-
nect the headliner washer hose from the barbed nip-
ple of the rear check valve.

REAR WIPERS/WASHERS (Continued)

headliner hose is glued to top of the headliner and
routed along the right roof side rail to the rear of the
vehicle. At the rear of the vehicle, the headliner hose
passes through a hole at the rear portion of the roof
rear inner header panel and is connected to the rear
check valve. From the rear check valve, there is a
short section of hose that connects the rear check
valve to the rear washer nozzle.
Washer hose is available for service only as roll
stock, which must then be cut to length. The head-
liner washer hose is integral to the headliner unit
and, if faulty or damaged, the headliner unit must be
replaced. However, the headliner hose is marked
with a white cut line on the A-pillar where the hose
should be cut and spliced with a plastic in-line con-
nector fitting to facilitate headliner removal without
the need to remove the instrument panel. (Refer to
23 - BODY/INTERIOR/HEADLINER - REMOVAL
AND INSTALLATION). The molded plastic washer
hose fittings cannot be repaired. If these fittings are
faulty or damaged, they must be replaced.
OPERATION
Washer fluid in the washer reservoir is pressurized
and fed by the washer pump/motor through the rear
washer system plumbing and fittings to the rear
washer nozzle located on the roof panel above the
rear flip-up glass opening. Whenever routing the
washer hose or a wire harness containing a washer
hose, it must be routed away from hot, sharp, or
moving parts; and, sharp bends that might pinch the
hose must be avoided.
REAR WASHER NOZZLE
DESCRIPTION
The rear washer nozzle is a fluidic-type unit con-
structed of molded plastic (Fig. 6). The nozzle is
secured by a snap fit in a dedicated mounting hole
located in the rear edge of the roof panel above the
rear flip-up glass opening and to the right of the
Center High Mounted Stop Lamp (CHMSL) unit. A
rubber gasket on the back of the nozzle seals the noz-
zle to the roof panel opening. The back of the nozzle
includes an integral alignment feature on the left
side, an integral engagement tab on the top, an inte-
gral latch feature on the bottom, and the washer
plumbing nipple which are all concealed between the
outer roof panel and the rear roof inner header. The
rear washer nozzle latch feature is a one time com-
ponent, and will be damaged if the nozzle is removed
from its mounting hole for service. The rear washer
nozzle cannot be adjusted or repaired. If faulty or
damaged, the entire nozzle unit must be replaced.
OPERATION
The rear washer nozzle is designed to dispense
washer fluid into the wiper pattern area on the out-
side of the rear flip-up glass. Pressurized washer
fluid is fed to the nozzle from the washer reservoir by
the washer pump/motor through a single hose, which
is attached to a barbed nipple on the back of the rear
washer nozzle. The rear washer nozzle incorporates a
fluidic design, which causes the nozzle to emit the
pressurized washer fluid as an oscillating stream to
more effectively cover a larger area of the glass area
to be cleaned.
REMOVAL
NOTE: The rear washer nozzle latch feature is a one
time component, and will be damaged if the nozzle is
removed from its mounting hole for service. If
removed from its mounting hole for any reason, the
rear washer nozzle must be replaced with a new unit.
(1) Using a trim stick or another suitable wide
flat-bladed tool, gently pry the bottom of the rear
washer nozzle away from the roof panel until the
latch feature at the bottom of the nozzle that secures
it in the mounting hole of the roof panel snaps.
(2) Pull the rear washer nozzle out from the roof
panel far enough to access the washer hose (Fig. 7).
(3) Disconnect the washer hose from the barbed
nipple on the back of the rear washer nozzle.
(4) Discard the rear washer nozzle.
