LATCH
DESCRIPTION
Vehicles equipped with a power liftgate, utilize a
power cinch/release latch. This latch performs the
same features as a manual liftgate latch as well as
the power cinch and / or release capability. A second
type of power latch can also be found on some RS
models, this latch is designed to perform a power
release only. The power cinch and release capability
is accomplished by an actuator mounted to the lead-
ing edge of the latch assembly. The latch is located in
the lower center of the liftgate assembly (Fig. 12) and
contains integral pawl and ratchet switches. The
ratchet switch acts as a liftgate ajar switch.
The power latch assembly can be serviced as a
complete assembly, latch without actuator or just the
actuator. Consult your Mopar parts catalog for spe-
cific part numbers.Fig. 11 LIFTGATE GEAR MOTOR ASSEMBLY

LATCH ACTUATOR
DESCRIPTION
Vehicles equipped with a power liftgate utilize a
power cinch latch or power release latch (Fig. 13).
The power cinch and/or power release is made possi-ble by a latch actuator attached to the leading edge
of the power latch assembly. This 12 volt latch actua-
tor contains a small drive gear that meshes with the
latch assemblies internal gears to perform the power
cinch close / power release operations. Refer to the
Latch assembly for more information.
The power cinch/release actuator is serviceable
component. Consult your MoparŸ parts catalog for
specific part numbers.
OPERATION
During a power close cycle, the power cinch actua-
tor provides the torque required to close the power
liftgate from the secondary to the primary closed and
latched position. During a power open cycle, the

EXTERIOR HANDLE SWITCH
DESCRIPTION
Vehicles equipped with a power liftgate or power
locks utilize a exterior handle switch. The exterior
handle switch is a electronic release switch mounted
to the rear license plate lamp housing assembly,
located just above the license plate. This switch con-
trols the power liftgate release function and is also
capable of reversing the power liftgate when it is in
motion. A full power open cycle cannot be performed
using this switch, only one of the power open com-
mand switches (key fob and overhead console
mounted) can be used to perform a full power open
cycle.The exterior handle switch is a serviceable compo-
nent. Consult your MoparŸ parts catalog for a spe-
cific part number.
OPERATION
When the exterior handle switch is depressed, with
the liftgate in the closed position. A message is sent
to the Body Control Module (BCM). The Body Con-
trol Module then sends a signal to the power liftgate
control module via the J1850 PCI data bus circuit.
The power liftgate control module then sends a sig-
nal to the power latch mounted actuator, which
moves the liftgate from the primary closed and
latched position to the open and movable position. If
the liftgate is not pulled open once the latch releases
within a few seconds, the latch will cinch closed
again.

STANDARD PROCEDURE
STANDARD PROCEDURE - WELLNUT
REPLACEMENT
Vehicles equipped with a power sliding door utilize
wellnuts. These wellnuts are used to hold and isolate
the power sliding door motor to and from the door
inner panel. The wellnut functions like a expandable
rubber core plug, as the screw fastener is threaded
into the wellnut and tightened the wellnuts diameter
increases. This secures the door motor assembly to
the inner panel and keeps the audible motor vibra-
tions to a minimum. If a wellnut shows signs of wear,
it must be replaced. Follow the procedure below if
replacement is necessary.
(1) Remove the door motor from the door inner
panel. (Refer to 8 - ELECTRICAL/POWER DOORS/
MOTOR - REMOVAL).
(2) Remove the wellnuts from the inner panel by
pulling them straight out (Fig. 4). If a wellnut is dif-
ficult to remove, use a high leverage cutting tool to
cut the wellnut in half and remove the two halves
from the door assembly.
(3) Install the replacement wellnuts in the inner
panel and install the door motor(Refer to 8 - ELEC-
TRICAL/POWER DOORS/MOTOR - INSTALLA-
TION) .CAUTION: Be certain to use the correct torque
specification (35 in.lbs.) when installing the door
motor retaining screws.STANDARD PROCEDURE - POWER DOOR
LEARN CYCLE
Any time a power side door component is removed,
replaced, door adjustment is performed or diagnostic
trouble codes are addressed and erased, a learn cycle
mustbe performed. This learn cycle enables the
power side door control module to learn or relearn its
critical information (travel limits, resistance to door
travel, etc.) which allows it to perform properly and
safely. It also tells the technician that the system is
performing properly and is able to be returned to ser-
vice. To perform a power door learn cycle do the fol-
lowing:
(1) Obtain a DRB IIItscan tool.
Connect the DRB IIItto the vehicle and check for
any power side door system stored diagnostic trouble
codes, erase any stored codes. Operate the system
and check to see if any trouble codes return. If any
diagnostic trouble codes return, diagnose, correct and
erase the codes before performing the learn cycle. If a
DRB IIItscan tool is not available, the learn cycle
can be performed by opening and closing the power
side door using any of the normal open/close com-
mand switches. Be certain to cycle the side door
through a complete openandclose cycle or the pro-
cedure will not be complete.
(2) Using the DRB IIIt, Go into Test Routine
Menu and select a power open command.
(3) Select a power close command.
(4) The power side door learn cycle is complete.
NOTE: If the power side door will not complete a
full cycle, a problem exists with the power side
door system. Refer to Power Side Door Diagnosis
and Testing.
STANDARD PROCEDURE - SLIDING DOOR
ADJUSTMENT
In order for the power sliding door system to func-
tion properly the door must move freely and
smoothly. The power sliding door system can accom-
modate for some minor changes in the effort required
to move the door. However, in extreme conditions the
door may need to be mechanically adjusted for proper
fit. (Refer to 23 - BODY/DOORS - SLIDING/SLID-
ING DOOR - ADJUSTMENTS).
If a problem exists with the power sliding door and
it is suspected to be extreme effort, check for proper
door alignment and adjustment first, then check the
door tracks and drive unit for free manual operation.

SLIDING DOOR MOTOR
DESCRIPTION
Vehicles equipped with a power sliding door utilize
a door motor assembly. The door motor is located in
the center of the side door (Fig. 7) and is comprised
of three parts. The three parts of the door motor
assembly are the motor, gear reduction and clutch
assembly. The door motor assembly provides the
power and torque to move the sliding door from the
open/closed position to full closed/open position, after
the power latching mechanism has released.
Special wellnuts and screws are used in the side
door inner panel to retain the door motor to the doorpanel. Refer to Standard Procedures in this section
for additional wellnut information.
The door motor is replaced as a complete assembly,
which includes the DC motor, gear reduction and
clutch assemblies. Consult your Mopar parts catalog
for specific part numbers.
OPERATION
With the push of a Power Side Door (PSD) com-
mand switch, the PSD control module will signal the
latch assembly to release the door from its primary
locked position. The drive motor will then take over
to provide the power to open the door to its full open
or closed position. The gear reduction portion of the
motor assembly reduces the speed of the motor from
5800 to 260 rpm and also increases the torque to the
lower drive unit. The clutch portion of the motor
assembly engages the motor to drive the door under
power and disengages it so the door can be moved
easily under manual operation.
REMOVAL

FULL OPEN SWITCH
DESCRIPTION
Vehicles equipped with a power sliding door utilize
a full open switch. This switch is located in the hold
open latch (Fig. 9) under the side door lower hinge.
When the power side door module receives a ground
signal input from the full open switch, and as long as
the cinching latch actuator is not in power mode or
the handle switch is open, the signal indicates that
the door is at the full open position.
The full open switch is incorporated into the hold
open latch. If the full open switch proves faulty, the
entire hold open latch assembly must be replaced.
OPERATION
The full open switch is triggered by a pawl lever in
the hold open latch. When the full open switch is
closed (circuit to ground) the ratchet has engaged on
the hold open striker and the pawl lever has engaged
on the ratchet, locking the latch from opening and

PASSENGER POWER SEAT
TRACK
DESCRIPTION
The eight-way power seat option includes a electri-
cally operated power seat track unit located under
each front seat. The power seat circuit breaker is
mounted on the rear of the power seat track, just
behind the seat rear trim panel. The lower half of the
power seat track is secured to the floor panel via four
studs and nuts that must be accessed from the
underside of the vehicle. Four bolts secure the bot-
tom of the seat cushion frame to the upper half of the
power seat track unit. Four additional bolts secure
the seat back frame to the power seat track unit.
The power seat track unit includes four reversible
electric motors that are secured to the upper half of
the track unit. Each motor moves the seat adjuster
through a combination of worm-drive gearboxes and
screw-type drive units.
The front and rear of the seat are operated by two
separate vertical adjustment motors. These motors
can be operated independently of each other, tilting
the entire seat assembly forward or rearward; or,
they can be operated in unison by selecting the
proper power seat switch functions, which will raise
or lower the entire seat assembly. A third motor is
the horizontal adjustment motor, which moves the
seat track in the forward and rearward directions.
The forth motor is the recliner adjustment motor,
which moves the seat back in the forward and rear-
ward directions.
