voltage at the rear washer switch output circuit cav-
ity of the left headlamp and dash wire harness con-
nector for the rear washer pump/motor unit. If OK,
replace the faulty rear washer pump/motor unit. If
not OK, repair the open rear washer switch output
circuit between the rear washer pump/motor unit
and the right multi-function switch as required.
CLEANING - REAR WIPER & WASHER SYSTEM
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 liftgate glass should only
be cleaned using a sponge or soft cloth and wind-
shield washer fluid, a mild detergent, or a non-abra-
sive 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.
WASHER SYSTEM
If the washer system is contaminated with foreign
material, drain the washer reservoir by removing the
front washer pump/motor from the reservoir. Clean
foreign material from the inside of the washer reser-
voir using clean washer fluid, a mild detergent, or a
non-abrasive 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 usingcompressed 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
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 ramp.
Note the action of the wiper arm hinge. The wiper
arm should pivot freely at the hinge, but with no lat-
eral 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. 1). If the wiper blade or squeegee is
contaminated with any foreign material, clean them
and the glass as required. (Refer to 8 - ELECTRI-
WJREAR WIPERS/WASHERS 8R - 37
REAR WIPERS/WASHERS (Continued)

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.
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 togetherusing 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 WASHER HOSES/TUBES
DESCRIPTION
The rear washer plumbing consists of small diam-
eter rubber hoses and molded plastic inline connector
fittings (Fig. 2). The washer reservoir hose is con-
nected to the barbed outlet nipple of the rear washer
pump/motor unit below the left front wheel house
extension and routed up the washer reservoir filler
neck to the engine compartment. Just rearward of
the washer reservoir filler neck in the engine com-
partment, an inline connector with barbed nipples
joins the reservoir hose to the engine compartment
hose. The engine compartment hose is routed along
the top of the left front fender wheel house to the
dash panel. The engine compartment hose passes
through a hole with a rubber grommet in the dash
panel into the passenger compartment. Below the
instrument panel in the passenger compartment near
the left cowl side inner panel, another inline connec-
tor joins the engine compartment hose to the A-pillar
hose. The A-pillar hose is routed up the left A-pillar
to the headliner. At the headliner, an inline connector
joins the A-pillar hose to the headliner hose. The
headliner hose is routed above the headliner and

REAR WASHER PUMP/MOTOR
DESCRIPTION
The rear washer pump/motor unit is located on the
outboard side and near the rear of the washer reser-
voir, between the left front inner and outer fender
panels (Fig. 5). A small permanently lubricated and
sealed electric motor is coupled to the rotor-type
washer pump. A seal flange with a large barbed inlet
nipple on the pump housing passes through a rubber
grommet seal installed in one of two dedicatedmounting holes near the bottom of the washer reser-
voir. The rear washer pump/motor unit is always
mounted in the higher pump mounting hole of the
reservoir. A smaller barbed outlet nipple on the pump
housing connects the unit to the rear washer hose.
The washer pump/motor unit is retained on the res-
ervoir by the interference fit between the barbed
pump inlet nipple and the grommet seal, which is a
light press fit. An integral electrical connector recep-
tacle is located on the top of the motor housing. The
rear washer pump/motor unit cannot be repaired. If
faulty or damaged, the entire washer pump/motor
unit must be replaced.
OPERATION
The rear washer pump/motor unit is connected to
the vehicle electrical system through a single take
out and two-cavity connector of the left headlamp
and dash wire harness. The washer pump/motor is
grounded at all times through a take out of the left
headlamp and dash wire harness with a single eyelet
terminal connector that is secured under a ground
screw to the top of the left inner fender shield in the
engine compartment. The rear washer pump/motor
receives battery current on a fused ignition switch
output (run-acc) circuit through the closed contacts of
the momentary rear washer switch within the right
multi-function switch only when the switch control
stalk is pushed towards the instrument panel.
Washer fluid is gravity-fed from the washer reservoir
to the inlet side of the washer pump. When the pump
motor is energized, the rotor-type pump pressurizes
