REMOVAL AND INSTALLATION.
The windshield wipers will only operate with the
ignition switch in the ACCESSORY or IGNITION
RUN position. The wiper circuit is protected against
over loads by a fuse in the fuse block and a circuit
breaker within the wiper motor. This protects the cir-
cuitry of the wiper system and the vehicle. The wiper
motor has permanent magnet fields.
The intermittent wiper system, in addition to low
and high speed, has a delay mode and a pulse wipe
mode. The delay mode has a range of 1 to 15 seconds.
Pulse wipe is accomplished by momentarily moving
the stalk lever into the WASH position while the
wiper switch is in either OFF or DELAY position.
The wiper blades then sweep once or twice and
return to the previous wiper switch mode, OFF or
DELAY.The intermittent wiper function is integral to the
wiper switch. All electronics and relay are inside the
switch assembly.
The wiper system completes the wipe cycle when
the switch is turned OFF. The blades park in the
lowest portion of the wipe pattern.
The wiper switch also includes the MIST feature
which provides a single wipe when actuated.
DESCRIPTION AND OPERATION
WIPER BLADES
Wiper blades, exposed to the weather for a long
period of time, tend to lose their wiping effectiveness.
Periodic cleaning of the wiper blade is suggested to
remove the accumulation of salt and road film. The
wiper blades, arms, and windshield should be
cleaned with a sponge or cloth and a mild detergent
or nonabrasive cleaner. If the blades continue to
streak or smear, they should be replaced. The right
and left wipers are different blade lengths. The
driver side length is 550 mm and the passenger side
length is 475 mm. The blades should not be inter-
changed.

connections, fuses, charging system, headlamp bulbs,
wire connectors, relay, high beam switch, dimmer
switch, and headlamp switch. Refer to Group 8W,
Wiring Diagrams for component locations and circuit
information.
SAFETY PRECAUTIONS
WARNING: EYE PROTECTION SHOULD BE USED
WHEN SERVICING GLASS COMPONENTS. PER-
SONAL INJURY CAN RESULT.
CAUTION: Do not touch the glass of halogen bulbs
with fingers or other possibly oily surface, reduced
bulb life will result.
Do not use bulbs with higher candle power than
indicated in the Bulb Application table at the end of
this group. Damage to lamp and/or Daytime Run-
ning Lamp Module can result.
Do not use fuses, circuit breakers or relays hav-
ing greater amperage value than indicated on the
fuse panel or in the Owners Manual.When it is necessary to remove components to ser-
vice another, it should not be necessary to apply
excessive force or bend a component to remove it.
Before damaging a trim component, verify hidden
fasteners or captured edges are not holding the com-
ponent in place.
DAYTIME RUNNING LAMP MODULE
PL vehicles built for use in Canada are equipped
with a Daytime Running Lamp (DRL) system. Turn
signal lamp circuitry always comes from the multi-
function switch, and goes to the cluster connector,
into the cluster, then back out to the front turn sig-
nal switch lamps. The Canadian cluster provides
steady illumination of the front turn signal when the
ignition switch is in the ON position. The DRL func-
tion may be inhibited by activating the turn signals,
the hazard flashers, the headlamp switch, or park
brake.
DIAGNOSIS AND TESTING
HEADLAMP DIAGNOSIS
Always begin any diagnosis by testing all of the
fuses and circuit breakers in the system. Refer to
Group 8W, Wiring Diagrams.

Following are general descriptions of the major
components in the power distribution system. Refer
to the owner's manual in the vehicle glove box for
more information on the features, use and operation
of all of the power distribution system components.
POWER DISTRIBUTION CENTER (PDC)
All of the electrical current distributed throughout
this vehicle is directed through the standard equip-ment Power Distribution Center (PDC). The molded
plastic PDC housing is located in the left front corner
of the engine compartment, just behind the air
cleaner housing and left of the battery (Fig. 1). The
PDC housing has a molded plastic cover. The PDC
cover is easily removed for service access and has a
convenient fuse and relay layout label affixed to the
inside surface of the cover to ensure proper compo-
nent identification.
The PDC housing is secured to the left inner
fender well an indexing pin and one screw. All of the
PDC outputs are through the integral engine com-
partment wire harness.
All of the current from the generator cable connec-
tion goes to the battery through a 140 ampere fusible
link that is secured with a nut to the positive battery
cable terminal. The PDC houses up to ten six fuse
cartridges, which replace all in-line fusible links. The
PDC also houses up to twelve blade-type fuses, up to
three full International Standards Organization
(ISO) relays, and up to eight mini International
Standards Organization (ISO) relays. Internal con-
nection of all the PDC circuits is accomplished by an
intricate network of hard wiring and bus bars. Refer
toPower Distributionin the Component Index of
Group 8W - Wiring Diagrams for complete circuit
diagrams.

The fusible link, fuses and relays are available for
service replacement. The PDC unit cannot be
repaired and is only serviced as a unit with the
engine compartment wire harness. If the PDC is
faulty or damaged, the engine compartment wire har-
ness assembly must be replaced.
FUSE BLOCK
An electrical Fuse Block is located in the left end
of the instrument panel (Fig. 2). It serves to simplify
and centralize numerous electrical components, as
well as to distribute electrical current to many of the
accessory systems in the vehicle.
The Fuse Block is positioned on a mounting
bracket up and under the left instrument panel. It is
secured by two screws. The fuse block is concealed
behind the left instrument panel end cap. The left
end cap is a snap-fit access cover that conceals the
fuse block fuses. A fuse layout placard is on the back
of the end cap to ensure proper fuse identification.
The fuse block houses blade-type fuses and auto-
matic resetting circuit breakers (Fig. 3). Internal con-
nection of all the fuse block circuits is accomplished
by an intricate network of hard wiring and bus bars.
Refer toJunction Blockin the Component Index of
Group 8W - Wiring Diagrams for complete circuit
diagrams.
The fuses and circuit breakers are available for
service replacement. The fuse block unit cannot be
repaired and is only serviced as an assembly. If any

DESCRIPTION AND OPERATION
INTRODUCTION
All doors can be locked or unlocked electrically by
operating the switch on either front door panel.
When the door lock switch is activated the Remote
Keyless Entry Module provides power to the door
lock motors through relays internal to the module.
The Remote Keyless Entry (RKE) Module also con-
trols the Vehicle Theft Security System (VTSS).
All doors can be locked or unlocked mechanically
and independently with their respective locking
knobs. The front doors can also be unlocked by actu-
ation of the inside remote door handle.
The RKE Module has three modes of operation
including customer usage mode, dealer lot storage
mode, and shipping mode. The customer usage mode
provides full functionality of the module and is the
mode in which the RKE module should be operating
when used by the customer. Dealer lot storage mode
and shipping modes are reduced power modes meant
to extend vehicle battery life during shipping and
storage in the dealer lot. Dealer lot storage mode pro-
vides limited VTSS and power door lock functions,
but disables the Remote Keyless Entry (RKE) func-
tions. This mode is intended to be used when the
vehicle is on the dealer lot to provide VTSS coverageof the vehicle while minimizing battery drain. Ship-
ping mode disables all normal functions (i.e. power
door locks, RKE, and VTSS) of the module, and is
intended to be used when the vehicle is shipped from
the assembly plant.
NOTE: The dealer must remove the module from
ªShip Modeº and place the RKE Module into either
the ªDealer Lotº storage or ªCustomer Usageº
modes of operation after receiving the vehicle from
the assembly plant. Refer to Group 8Q-Vehicle
Theft/Security Systems, Switching Operating
Modes/Configuring a New Module under Service
Procedures.
CENTRAL LOCKING/UNLOCKING
The door locks can be locked or unlocked electri-
cally via the exterior door key cylinders to provide
the central locking/unlocking feature. The central
locking/unlocking feature incorporates a customer
programmable ``Double activation unlockº feature
which operates in the following manner: When
enabled, the first turn of the key cylinder to the
UNLOCK position (toward the front of the vehicle)
will mechanically unlock the door whose key cylinder
is being turned. A second turn of the key cylinder to
the UNLOCK position (within five seconds of the
PLPOWER LOCK SYSTEMS 8P - 1

first turn) will cause all vehicle doors to unlock elec-
trically. When this feature is disabled, all vehicle
doors will be unlocked electrically upon the first turn
of a key cylinder to the UNLOCK position. The vehi-
cle is locked electrically by turning the key cylinder
to the LOCK position once, regardless of the state of
the double activation unlock feature.
POWER DOOR LOCKS
The Remote Keyless Entry (RKE) Module actuates
the power door lock relays when a door lock switch is
activated. If the door lock switch is pressed for longer
than eight consecutive seconds, the RKE module will
de-energize the door lock motors.
The system includes the rolling door locking fea-
ture. The vehicle is shipped with the system enabled.
When the system is disabled the door locks will work
by use of the door lock switches and the Remote Key-
less Entry system only. When the rolling door lock
system is enabled, the RKE module will automati-
cally lock all the vehicle doors when all of the follow-
ing conditions are met:
²All doors are closed
²The vehicle speed exceeds 15 +/- 1 mph.
²The throttle position sensor tip-in is greater
than 10 +/- 2 degrees.
The RKE module will automatically re-lock all
doors if the above conditions are met and if any of
the doors become ajar and then closed again.
The enabling/disabling of the rolling door lock fea-
ture is customer programmable, as well as program-
mable with the DRB IIItscan tool.
The power lock motors are also equipped with a
thermal protection system which prevents the motors
from burning out. The motors may chatter if they are
continuously activated.
CHILD PROTECTION LOCKS
The child protection locks are on the rear doors
only. The lock, when engaged, will disable the inside
door handle from opening the door. The lock is part
of the latch/lock assembly. The lock is engaged by
moving a lever that is located on the rearward inside
edge of the door.
DOOR LOCK INHIBIT
With the key in the ignition switch and the driver
door open, the Remote Keyless Entry (RKE) Modulewill ignore the command to lock the power door locks
via the interior driver door lock switch. Once the key
is removed, or the driver door is closed, the RKE
module will allow the power door locks to lock via the
interior door lock switches.
DIAGNOSIS AND TESTING
DOOR LOCK MOTOR
(1) Make certain battery is in normal condition
and fuses powering the RKE module aren't blown
before circuits are tested.
(2) To determine which motor is faulty, check each
individual door for electrical lock and unlock or dis-
connect the motor connectors one at a time, while
operating the door lock switch.
(3) In the event that none of the motors work, the
problem maybe caused by a shorted motor, a bad
switch or a bad relay internal to the RKE module.
Disconnecting a defective motor will allow the others
to work.
(4) To test an individual door lock motor, discon-
nect the electrical connector from the motor.
(5) To lock the door, connect a 12 volt power source
to one pin of the lock motor and a ground wire to the
other pin.
(6) To unlock the door, reverse the wire connec-
tions at the motor pin terminals.
(7) If these results are NOT obtained, replace the
motor.
DOOR LOCK SWITCH
(1) Remove the switch from its mounting location,
and disconnect from vehicle wiring harness. Refer to
Door Lock Switch Removal and Installation in this
section.
(2) Using an ohmmeter, refer to Door Lock Switch
Resistance Test table to determine if switch resis-
tance is correct in the Lock and Unlock switch posi-
tions. Refer to Group 8W-Wiring Diagrams for
harness connector pin-outs.
