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).

module and the multi-function switch as required.
REAR WASHER SYSTEM
The diagnosis found here addresses an electrically
inoperative rear washer system. If the washer pump/
motor operates, but no washer fluid is emitted from
the rear washer nozzle, be certain to check the fluid
level in the reservoir. Also inspect the rear washer
system components as required. (Refer to 8 - ELEC-
TRICAL/REAR WIPERS/WASHERS - INSPECTION).
Refer to the appropriate wiring information. The wir-
ing information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
information and location views for the various wire
harness connectors, splices and grounds.
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE SUPPLEMENTAL RESTRAINT
SYSTEM BEFORE ATTEMPTING ANY STEERING
WHEEL, STEERING COLUMN, DRIVER AIRBAG,
PASSENGER AIRBAG, SEAT BELT TENSIONER,
SIDE CURTAIN AIRBAG, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. DISCON-
NECT AND ISOLATE THE BATTERY NEGATIVE
(GROUND) CABLE, THEN WAIT TWO MINUTES FOR
THE SYSTEM CAPACITOR TO DISCHARGE BEFORE
PERFORMING FURTHER DIAGNOSIS OR SERVICE.
THIS IS THE ONLY SURE WAY TO DISABLE THE
SUPPLEMENTAL RESTRAINT SYSTEM. FAILURE TO
TAKE THE PROPER PRECAUTIONS COULD
RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND POSSIBLE PERSONAL INJURY.
(1) Turn the ignition switch to the On position.
Turn the control ring on the right (wiper) control
stalk of the multi-function switch to the On position.
Check whether the rear wiper system is operating. If
OK, go to Step 2. If not OK, test and repair the rear
wiper system before continuing with these tests.
Refer to REAR WIPER SYSTEM .
(2) Pull the right (wiper) control stalk of the multi-
function switch toward the steering wheel. Check
whether the front washer system is operating. If OK,
test the multi-function switch. (Refer to 8 - ELEC-
TRICAL/LAMPS/LIGHTING - EXTERIOR/MULTI-
FUNCTION SWITCH - DIAGNOSIS AND
TESTING). If the multi-function switch tests OK, go
to Step 3. If the multi-function switch does not test
OK, replace the faulty switch.
(3) Turn the ignition switch to the Off position.
Disconnect and isolate the battery negative cable.
Disconnect the headlamp and dash wire harness con-
nector for the washer pump/motor unit from the
pump/motor unit connector receptacle. Check for con-
tinuity between the washer pump driver circuit cav-ity of the headlamp and dash wire harness connector
for the washer pump/motor unit and a good ground.
There should be no continuity. If OK, go to Step 4. If
not OK, repair the shorted washer pump driver cir-
cuit between the washer pump/motor unit and the
multi-function switch as required.
(4) Check for continuity between the washer pump
driver circuit cavities of the headlamp and dash wire
harness connector for the washer pump/motor unit
and the instrument panel wire harness connector for
the multi-function switch (Connector C-2). There
should be continuity. If OK, go to Step 5. If not OK,
repair the open washer pump driver circuit between
the washer pump/motor unit and the multi-function
switch as required.
(5) Check for continuity between the washer pump
sense circuit cavity of the headlamp and dash wire
harness connector for the washer pump/motor unit
and a good ground. There should be no continuity. If
OK, go to Step 6. If not OK, repair the shorted
washer pump sense circuit between the washer
pump/motor unit and the multi-function switch as
required.
(6) Check for continuity between the washer pump
sense circuit cavities of the headlamp and dash wire
harness connector for the washer pump/motor unit
and the instrument panel wire harness connector for
the multi-function switch (Connector C-2). There
should be continuity. If OK, replace the faulty washer
pump/motor unit. If not OK, repair the open washer
pump sense circuit between the washer pump/motor
unit and the multi-function switch as required.
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.
