FRONT WASHER NOZZLE
DESCRIPTION
The two front washer nozzles have integral snap
features and an anti-rotation tab that secure them in
dedicated holes in the cowl plenum cover/grille panel
located near the base of the windshield (Fig. 7). The
domed upper surface of the washer nozzle is visible
on the top of the plenum cover/grille panel, and the
nozzle orifice is oriented towards the windshield
glass. The washer plumbing fittings for the washer
nozzles are concealed beneath the cowl plenum cover/
grille panel. These fluidic washer nozzles are con-
structed of molded plastic. The cowl plenum cover/
grille panel must be removed from the vehicle to
access the nozzles for service. The washer nozzles
cannot be adjusted or repaired. If faulty or damaged,
they must be replaced.
OPERATION
The two front washer nozzles are designed to dis-
pense washer fluid into the wiper pattern area on the
outside of the windshield glass. Pressurized washer
fluid is fed to each nozzle from the washer reservoir
by the washer pump/motor unit through a single
hose, which is attached to a barbed nipple on each
front washer nozzle below the cowl plenum cover/
grille panel. The washer nozzles incorporate a fluidic
design, which causes the nozzle to emit the pressur-
ized washer fluid as an oscillating stream to more
effectively cover a larger area of the glass area to be
cleaned.

WASHER FLUID LEVEL
SWITCH
DESCRIPTION
The washer fluid level switch is a single pole, sin-
gle throw reed-type switch mounted at the rear of
the sump area near the bottom of the washer reser-
voir (Fig. 16). Only the molded plastic switch mount-
ing flange and the integral connector receptacle are
visible when the switch is installed in the reservoir.
A short nipple formation extends from the inner sur-
face of the switch mounting flange, and a barb on the
nipple near the switch mounting flange is pressed
through a rubber grommet seal installed in the
mounting hole of the reservoir. A small, molded plas-
tic float has two pivot pins near its center that are
snapped into two receptacles near the ends of two
stanchions that extend toward the float from the
switch nipple formation. A small magnet is secured
within the end of the float nearest the switch nipple
formation, and a reed switch is concealed within the
nipple. A diagnostic resistor is connected between the
two switch terminals within the switch mounting
flange. The washer fluid level switch cannot be
adjusted or repaired. If faulty or damaged, the switch
must be replaced.
OPERATION
The washer fluid level switch uses a pivoting,
oblong float to monitor the level of the washer fluid
in the washer reservoir. The float contains a small
magnet. When the float pivots, the proximity of this
magnet to a stationary reed switch within the nipple
formation of the switch changes. When the fluid level
in the washer reservoir is at or above the float level,
the float moves to a vertical position, the influence of
the float magnetic field is removed from the reed
switch, and the normally open reed switch contacts
open. When the fluid level in the washer reservoir
falls below the level of the pivoting float, the float
moves to a horizontal position, the influence of the
float magnetic field is applied to the reed switch, and
the contacts of the normally open reed switch close.
The washer fluid level switch is connected to the
vehicle electrical system through a dedicated take
out and connector of the headlamp and dash wire
harness. The switch is connected in series between
ground and the washer fluid switch sense input to
the ElectroMechanical Instrument Cluster (EMIC).
The switch receives a path to ground at all times
through another take out of the headlamp and dash
wire harness with a single eyelet terminal connector
that is secured under a ground screw near the front
of the left front fender inner shield in the engine
compartment. When the switch closes, the EMIC
senses the ground on the washer fluid switch sense
circuit. The EMIC is programmed to respond to this
input by illuminating the washer fluid indicator and
by sounding an audible chime tone warning.
The washer fluid level switch input to the EMIC
can be diagnosed using conventional diagnostic tools
and methods. (Refer to 8 - ELECTRICAL/INSTRU-
MENT CLUSTER/WASHER FLUID INDICATOR -
DIAGNOSIS AND TESTING).
REMOVAL
The washer fluid level switch can be removed from
the washer reservoir without removing the reservoir
from the vehicle.
(1) Disconnect and isolate the battery negative
cable.
(2) Raise and support the vehicle.
(3) Remove the splash shield from the right front
fender wheel house. (Refer to 23 - BODY/EXTERIOR/

WASHER PUMP/MOTOR
DESCRIPTION
The washer pump/motor unit (Fig. 18) is located on
the outboard side of the washer reservoir, on the out-
board side of the right front frame rail behind the
right front wheel house splash shield. A small perma-
nently lubricated and sealed reversible electric motor
is coupled to the rotor-type washer pump. The use of
an integral shuttle valve allows the washer pump/
motor unit to provide washer fluid to either the front
or the rear washer systems, depending upon the
direction of the motor/pump impeller rotation. A seal
flange with a barbed inlet nipple on the pump hous-
ing passes through a rubber grommet seal installed
in a dedicated mounting hole of the washer reservoir.
When the pump is installed in the reservoir the front
barbed outlet nipple on the pump shuttle valve hous-
ing connects the unit to the front washer hose and
the rear barbed outlet nipple connects the unit to the
rear washer hose. The letters ªFº and ªRº molded
into the shuttle valve housing adjacent to each nipple
provide further clarification of the nipple assign-
ments.
The washer pump/motor unit is retained on the
reservoir by the interference fit between the barbed
pump inlet nipple and the grommet seal, which is a
light press fit. The top of the washer pump is also
secured to the washer reservoir by the use of a snap
post on the motor and a snap post receptacle molded
into the reservoir that allows for mounting of the
washer pump without the use of fasteners. An inte-
gral connector receptacle on the top of the motor

housing connects the unit to the vehicle electrical
system through a dedicated take out and connector of
the headlamp and dash wire harness. The washer
pump/motor unit cannot be repaired. If faulty or
damaged, the entire washer pump/motor unit must
be replaced.
OPERATION
The washer pump/motor unit features a reversible
electric motor. The direction of the motor is con-
trolled by hard wired outputs from the momentary
front and rear washer switch circuitry contained
within the right (wiper) control stalk of the multi-
function switch. When battery current and ground
are applied to the two pump motor terminals, the
motor rotates in one direction. When the polarity of
these connections is reversed, the motor rotates in
the opposite direction. When the pump motor is ener-
gized, the rotor-type pump pressurizes the washer
fluid and forces it through one of the two pump out-
let nipples, and into the front or rear washer plumb-
ing.Washer fluid is gravity-fed from the washer reser-
voir to the inlet port of the washer pump housing. An
integral shuttle valve is located in a housing on the
outlet port side of the pump housing (Fig. 19). This
shuttle valve controls which washer system plumbing
receives the washer fluid being pressurized by the
pump. When the pump impeller rotates in the coun-
terclockwise direction (viewed from the bottom), pres-
surized washer fluid is pushed out the front washer
system port and biases the shuttle valve to the left,
sealing off the rear washer system outlet nipple.
When the pump impeller rotates in the clockwise
direction (viewed from the bottom), pressurized
washer fluid is pushed out the rear washer system
port and biases the shuttle valve to the right, sealing
off the front washer system outlet nipple.
The washer pump/motor unit can be diagnosed
using conventional diagnostic tools and methods.

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.

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.
