and pulling forward on the front bumper fascia,
remove the screw that secures the washer reservoir
to the right front frame rail.
(15) Remove the screw that secures the rear of the
washer reservoir to the right front frame rail.
(16) Disengage the mounting tab at the back of the
washer reservoir from the slot in the right front
frame rail.
(17) Lower the washer reservoir far enough for the
filler neck to be removed from the clearance hole in
the right front fender wheel house panel extension.
(18) Remove the washer reservoir from the right
front fender wheel house.
INSTALLATION
(1) Position the washer reservoir into the right
front fender wheel house.
(2) Insert the washer reservoir filler neck through
the clearance hole in the right front fender wheel
house panel extension (Fig. 24).
(3) Raise the washer reservoir far enough to
engage the mounting tab at the back of the reservoir
into the slot in the right front frame rail.
(4) Install and tighten the screw that secures the
rear of the washer reservoir to the right front frame
rail. Tighten the screw to 7 N´m (65 in. lbs.).
(5) Using a long extension with a swivel socket
and pulling forward on the front bumper fascia,
install and tighten the screw that secures the washer
reservoir to the right front frame rail. Tighten the
screw to 7 N´m (65 in. lbs.).
(6) Engage the front and rear washer hoses into
the integral washer reservoir troughs and routing
clips. Be certain that the rear washer hose is routed
rearward of the washer pump/motor unit, and the
front washer hose is routed forward of the washer
pump/motor unit. The rear washer hose can be iden-
tified by an in-line hose connector that joins the res-
ervoir hose to the engine compartment hose located
near the top of main body of the reservoir.
(7) Reconnect the headlamp and dash wire harness
connector for the washer fluid level switch to the con-
nector receptacle on the bottom of the switch.
(8) Reconnect the headlamp and dash wire harness
connector for the washer pump/motor unit to the con-
nector receptacle on the top of the motor housing.
(9) Reconnect the front and rear washer hoses to
the washer pump/motor unit outlet nipples. Be cer-
tain that the rear washer hose in the trough rear-
ward of the washer pump/motor unit is connected to
the rear nipple, and the hose in the trough forward

(10) Engage the ªWº clip that secures the front
bumper fascia to the front bumper support. This clip
is located behind the bumper support and below the
right front lamp unit.
(11) Reinstall the splash shield into the right front
fender wheel house. (Refer to 23 - BODY/EXTERIOR/
WHEELHOUSE SPLASH SHIELD - INSTALLA-
TION).
(12) Lower the vehicle.
(13) Install and tighten the screw that secures the
washer reservoir filler neck support to upper radiator
crossmember (Fig. 23). Tighten the screw to 7 N´m
(65 in. lbs.).
(14) Reinstall the air cleaner housing onto the top
of the right front fender wheel house. (Refer to 9 -
ENGINE/AIR INTAKE SYSTEM/AIR CLEANER
ELEMENT - INSTALLATION).
(15) Refill the washer reservoir with the washer
fluid drained from the reservoir during the removal
procedure.
(16) Reconnect the battery negative cable.
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.
