(FCM) on a sensor return circuit and the washer
fluid switch sense input to the FCM. When the
switch closes, the FCM senses the ground on the
washer fluid switch sense circuit. The FCM is pro-
grammed to respond to this input by sending an elec-
tronic washer fluid indicator lamp-on message to the
instrument cluster over the Programmable Commu-
nications Interface (PCI) data bus. The instrument
cluster responds to this message by illuminating the
washer fluid indicator and by sounding an audible
chime tone warning.
The washer fluid level switch may be diagnosed
and tested using conventional diagnostic tools and
procedures. However, conventional diagnostic meth-
ods may not prove conclusive in the diagnosis of the
instrument cluster, the FCM, or the electronic mes-
sage inputs to or outputs from the instrument cluster
and the FCM that control the operation of the
washer fluid visual and/or audible indicators. The
most reliable, efficient, and accurate means to diag-
nose the washer fluid level indicator, the instrument
cluster, the FCM, or the electronic message inputs
and outputs related to the washer fluid indicator
requires the use of a DRBIIItscan tool. Refer to the
appropriate diagnostic information.

WASHER HOSES/TUBES
DESCRIPTION
The washer plumbing consists of a small diameter
rubber reservoir washer hose that is routed from the
barbed outlet nipple of the electric washer pump/mo-tor unit on the washer reservoir through a trough
molded into the back of the reservoir above the
washer pump and to the engine compartment washer
hose (Fig. 9). On models equipped with an optional
diesel engine, the reservoir washer hose is routed
through routing clips on the top of the radiator fan
shroud from the washer reservoir on the left side of
the radiator to the engine compartment washer hose
on the right side of the radiator. The engine compart-
ment washer hose is contained within the right head-
lamp and dash wire harness, which is routed through
the engine compartment along the top of the right
front fender wheel house to the dash panel.
The engine compartment washer hose is connected
to the washer reservoir washer hose and to the cowl
plenum washer hose with molded plastic in-line fit-
tings that have a barbed nipple on each end. The
cowl plenum washer hose is routed from the engine
compartment into the cowl plenum area through a
trough formation located near the right end of the
cowl plenum cover/grille panel. The cowl plenum
washer hose is connected to the washer system check
valve/wye fitting on the underside of the cowl plenum
cover/grille panel. The cowl plenum washer hose and
the two washer nozzle hoses are routed through inte-
gral routing clips on the underside of the cowl ple-
num cover/grille panel. The cowl plenum washer hose
is connected to one nipple on the wye fitting and the
two washer nozzle hoses are connected to the other
two wye fitting nipples. The washer nozzle hoses are
then routed along the underside of the cowl plenum
cover/grille panel to the two washer nozzles.
Washer hose is available for service only as roll
stock, which must then be cut to length. The molded
plastic washer hose fittings cannot be repaired. If
these fittings are faulty or damaged, they must be
replaced.
OPERATION
Washer fluid in the washer reservoir is pressurized
and fed by the washer pump/motor through the
washer system plumbing and fittings to the two
washer nozzles. Whenever routing the washer hose
or a wire harness containing a washer hose, it must
be routed away from hot, sharp, or moving parts;
and, sharp bends that might pinch the hose must be
avoided.
WASHER NOZZLE
DESCRIPTION
The two washer nozzles have integral snap fea-
tures 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. 10). 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 washer nozzles are designed to dispense
washer fluid into the wiper pattern area on the out-
side 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 washer
nozzle below the cowl plenum cover/grille panel. A
fluidic matrix within the washer nozzle causes the
pressurized washer fluid to be emitted from the noz-
zle orifice as an oscillating stream to more effectively
cover a larger area of the glass to be cleaned.

WASHER RESERVOIR
DESCRIPTION
Except on models equipped with an optional diesel
engine, the molded plastic washer fluid reservoir is
mounted on the right rearward facing surface of the
cooling module radiator shroud in the engine com-
partment (Fig. 14). On models with the diesel engine,
the molded plastic washer fluid reservoir is mounted
on the rearward facing surface of the left vertical
member of the radiator support in the engine com-
partment. The reservoir is a molded unit constructed
of a translucent plastic that allows the washer fluid
level to be inspected without removing the washer

reservoir cap. The most visible component of the
washer reservoir is the filler cap unit, which is
secured to and hinges on a hook feature that is inte-
gral to the filler neck near the top of the reservoir.
The bright yellow plastic filler cap snaps over the
filler neck opening and seals the reservoir opening
with an integral rubber gasket. The filler cap is
labeled with an International Control and Display
Symbol icon for ªWindshield Washerº and the text
ªWasher Fluid Onlyº that are molded into it and
highlighted in black against the yellow plastic cap for
visibility.
There are dedicated holes near the bottom of the
rearward facing side of the reservoir provided for the
mounting of the washer pump/motor unit and the
washer fluid level switch. A snap post receptacle
molded into the reservoir allows for mounting of the
washer pump without the use of fasteners. The res-
ervoir also features an integral hose routing trough
on its rearward facing side. Except on models with a
diesel engine, the washer reservoir is secured to the
cooling module radiator shroud with three integral
tabs, two at the bottom and one at the top. The two
bottom tabs are inserted into two slots near the bot-tom of the shroud, while the upper tab slides into an
integral channel-like slot near the top of the shroud.
A molded lock feature on the forward facing surface
of the reservoir engages a molded depression on the
rearward facing surface of the radiator shroud when
the reservoir is fully seated on the shroud, locking
the unit securely in place. On models with a diesel
engine, the washer reservoir is secured with two
screws through integral mounting tabs to the left
vertical member of the radiator support. On many
models, a molded plastic coolant recovery container
or a coolant pressure container must be detached
from the top of the cooling module and moved aside
to access the washer fluid reservoir for service. This
may be accomplished without opening or draining the
engine cooling system.
OPERATION
The washer fluid reservoir provides a secure,
on-vehicle storage location for a large reserve of
washer fluid for operation of the washer system. The
washer reservoir filler neck provides 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 bottom
of the reservoir to be certain that washer fluid will
be available to the pump as the fluid level in the res-
ervoir 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, well before the washer sys-
tem will no longer operate.

OPERATION
The wiper module operation is controlled by the
battery current inputs received by the wiper motor
through the wiper on/off and wiper high/low relays.
The wiper motor speed is controlled by current flow
to either the low speed or the high speed set of
brushes. The park switch is a single pole, single
throw, momentary switch within the wiper motor
that is mechanically actuated by the wiper motor
transmission components. The park switch alter-
nately opens and closes the wiper park switch sense
circuit to ground, depending upon the position of the
wipers on the glass. This feature allows the motor to
complete its current wipe cycle after the wiper sys-
tem has been turned Off, and to park the wiper
blades in the lowest portion of the wipe pattern. The
automatic resetting circuit breaker protects the
motor from overloads. The wiper motor crank arm,
the two wiper linkage members, and the two wiper
pivots mechanically convert the rotary output of the
wiper motor to the back and forth wiping motion of
the wiper arms and blades on the glass.
