2002 JEEP LIBERTY turn

OPERATION
The front check valve provides more than one func-
tion in this application. It serves as a wye connector
fitting between the cowl grille panel and washer noz-
zle sections of the front washer supply hose. It also
prevents washer fluid from draining out of the front
washer supply hoses back to the washer reservoir.
This drain-back would result in a lengthy delay when
the front washer switch is actuated until washer
fluid was dispensed through the front washer noz-
zles, because the washer pump would have to refill
the front washer plumbing from the reservoir to the
nozzles. Finally, the front check valve prevents
washer fluid from siphoning through the front
washer nozzles after the front washer system is
turned Off.
Within the check valve body, a small check valve is
held in place against a seat by a small coiled spring
to restrict flow through the unit until the valve is
unseated by a predetermined inlet fluid pressure.
When the washer pump pressurizes and pumps
washer fluid from the reservoir through the front
washer plumbing, the fluid pressure overrides the
spring pressure applied to the check valve and
unseats the valve, allowing washer fluid to flow
toward the front washer nozzles. When the washer
pump stops operating, spring pressure seats the
check valve and fluid flow in either direction within
the front washer plumbing is prevented.

FRONT WIPER BLADE
DESCRIPTION
Each front wiper blade is secured by an integral
latching pivot block to the hook formation on the tip
of the front wiper arms, and rests on the glass near
the base of the windshield when the wipers are not
in operation (Fig. 12). The wiper blade consists of the
following components:
²Superstructure- The superstructure includes
several stamped steel bridges and links with claw
formations that grip the wiper blade element. Also
included in this unit is the latching, molded plastic
pivot block that secures the superstructure to the
wiper arm. The driver side front wiper blade has an
additional molded black plastic airfoil secured to the
superstructure, which is oriented toward the base of
the windshield when the front wipers are in their
parked position. All of the metal components of the
wiper blade have a satin black finish applied.
²Element- The wiper element or squeegee is the
resilient rubber member of the wiper blade that con-
tacts the glass.
²Flexor- The flexor is a rigid metal component
running along the length of each side of the wiper

allows the motor to complete its current wipe cycle
after the wiper system 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 out-
put of the wiper motor to the back and forth wiping
motion of the wiper arms and blades on the glass.

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.
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.

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.

WIPER ON/OFF RELAY
DESCRIPTION
The wiper on/off relay is located in the Power Dis-
tribution Center (PDC) in the engine compartment
near the battery. The wiper on/off relay is a conven-
tional International Standards Organization (ISO)
micro relay (Fig. 28). Relays conforming to the ISO
specifications have common physical dimensions, cur-
rent capacities, terminal patterns, and terminal func-
tions. The relay is contained within a small,
rectangular, molded plastic housing and is connected
to all of the required inputs and outputs by five inte-
gral male spade-type terminals that extend from the
bottom of the relay base.
The wiper on/off relay cannot be adjusted or
repaired and, if faulty or damaged, the unit must be
replaced.
OPERATION
The wiper on/off 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 on/off 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 on/off relay
include:
²Common Feed Terminal- The common feed
terminal (30) is connected to the common feed termi-
nal of the wiper high/low 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 on/off
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) receives battery current at all times
from a circuit breaker in the Junction Block (JB)
through a fused ignition switch output (run-acc) cir-
cuit, and provides battery current to the front wiper
on/off relay output circuit whenever the relay is ener-
gized.
²Normally Closed Terminal- The normally
closed terminal (87A) is connected to the wiper park
switch in the front wiper motor through the front
wiper park switch sense circuit, and is connected to
the wiper park switch whenever the relay is de-ener-
gized.
The wiper on/off relay can be diagnosed using con-
ventional diagnostic tools and methods.

²Rear Wiper Module- The rear wiper motor
output shaft is the only visible component of the rear
wiper module. The remainder of the module is con-
cealed within the tailgate below the rear flip-up glass
opening. The rear wiper module includes the module
bracket, the rear wiper motor, and the rear wiper
electronic control circuitry.
²Washer Pump/Motor- The reversible electric
washer pump/motor unit is located in a dedicated
hole on the lower outboard side of the washer reser-
voir, behind the right front wheel house splash
shield. This single reversible washer pump/motor
provides washer fluid to either the front or rear
washer system plumbing, depending upon the direc-
tion of the pump motor rotation. (Refer to 8 - ELEC-
TRICAL/FRONT WIPERS/WASHERS/WASHER
PUMP MOTOR - DESCRIPTION).
²Washer Reservoir- The washer reservoir is
concealed behind the right front wheel house splash
shield ahead of the right front wheel. The washer
reservoir filler neck is the only visible portion of the
reservoir, and it is accessed from the right front cor-
ner of the engine compartment. This single washer
reservoir is shared by both the front and rear washer
systems. (Refer to 8 - ELECTRICAL/FRONT WIP-
ERS/WASHERS/WASHER RESERVOIR - DESCRIP-
TION).
Hard wired circuitry connects the rear wiper and
washer system components to the electrical system of
the vehicle. These hard wired circuits are integral to
several wire harnesses, which are routed throughout
the vehicle and retained by many different methods.
These circuits may be connected to each other, to the
vehicle electrical system and to the rear wiper and
washer system components through the use of a com-
bination of soldered splices, splice block connectors,
and many different types of wire harness terminal
connectors and insulators. Refer to the appropriate
wiring information. The wiring information includes
wiring diagrams, proper wire and connector repair
procedures, further details on wire harness routing
and retention, as well as pin-out and location views
for the various wire harness connectors, splices and
grounds.
OPERATING MODES The components of the rear
wiper and washer system are designed to work in
concert to provide the following operating modes:
²Continuous Wipe Mode- The control ring on
the right (wiper) control stalk of the multi-function
switch has an On position. When selected, this
switch position will cause the rear wiper motor to
operate in a continuous manner at a fixed wipe cycle
speed.
²Intermittent Wipe Mode- The control ring on
the right (wiper) control stalk of the multi-function
switch has a Delay position. When selected, thisswitch position will cause the rear wiper motor to
operate in an intermittent manner at a fixed interval
wipe cycle speed.
²Washer Mode- The control ring on the right
(wiper) control stalk of the multi-function switch has
two momentary Wash positions, one at the end of
each direction of control ring rotation. When the con-
trol ring is rotated to the downward (counterclock-
wise) Wash position, the rear washer system will
dispense washer fluid onto the flip-up glass and the
rear wiper motor will operate in a continuous mode
for as long as the switch is held closed, then provide
several additional wipe cycles after the washer
switch is released (wipe-after-wash mode). When the
control ring is rotated to the upward (clockwise)
Wash position, the rear washer system will dispense
washer fluid onto the flip-up glass and the rear wiper
motor will operate in a continuous mode for as long
as the switch is held closed, then return to fixed wipe
mode operation after the washer switch is released.
²Wipe-After-Wash Mode- The control ring on
the right (wiper) control stalk of the multi-function
switch has two momentary Wash positions, one at
the end of each direction of control ring rotation.
When the control ring is rotated to the downward
(counterclockwise) Wash position, the rear washer
system will dispense washer fluid onto the flip-up
glass and the rear wiper motor will operate in a con-
tinuous mode for as long as the switch is held closed,
then provide several additional wipe cycles after the
washer switch is released.
OPERATION
The rear wiper and washer system is designed to
provide the vehicle operator with a convenient, safe,
and reliable means of maintaining visibility through
the rear flip-up glass. The various components of this
system are designed to convert electrical energy pro-
duced by the vehicle electrical system into the
mechanical action of the wiper blade to wipe the out-
side surface of the glass, as well as into the hydraulic
action of the washer system to apply washer fluid
stored in an on-board reservoir to the area of the
glass to be wiped. When combined, these components
provide the means to effectively maintain clear visi-
bility for the vehicle operator by removing excess
accumulations of rain, snow, bugs, mud, or other
minor debris from the swing gate flip up glass sur-
face that might be encountered while driving the
vehicle under numerous types of inclement operating
conditions.
The vehicle operator initiates all rear wiper and
washer system functions with the right (wiper) con-
trol stalk of the multi-function switch that extends
from the right side of the steering column, just below
the steering wheel. Rotating the control ring on the
