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

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.

²Normally Closed Terminal- The normally
closed terminal (87A) is connected to the low speed
brush of the front wiper motor through a front wiper
high/low relay low speed output circuit, and is con-
nected to the low speed brush whenever the relay is
de-energized.
The wiper high/low relay can be diagnosed using
conventional diagnostic tools and methods.

REAR WASHER HOSES/TUBES
DESCRIPTION
The rear washer plumbing consists of small diam-
eter rubber hose routed from the barbed outlet nipple
of the reversible electric washer pump/motor unit on
the washer reservoir through a trough molded into
the reservoir rearward of the washer pump up to the
top of the reservoir. Near the base of the reservoir
filler neck an in-line plastic fitting connects the res-
ervoir rear washer hose to the engine compartment
rear washer hose, which is routed through the reser-
voir filler neck opening in the front extension of the
right front fender wheel house panel in to the engine
compartment. The engine compartment rear washer
hose is routed side by side with the front washer
hose along the top of the right front fender wheel
house to the dash panel. Molded plastic routing clips
secure the hoses to the headlamp and dash wire har-
ness in the engine compartment.
The engine compartment rear washer hose is con-
nected to the headliner washer hose near the right
side of the dash panel with a molded plastic in-line
fitting (Fig. 5). The headliner hose has a rubber
grommet that allows it to pass through the dash
panel from the passenger compartment into the
engine compartment. The headliner hose is routed
below the instrument panel in the passenger com-
partment near the right cowl side inner panel. The
hose is routed up the right A-pillar to the headliner.
Mounting clips secure the hose to the A-pillar. The
