DODGE TOWN AND COUNTRY 2004 Service Manual

CHIME/THERMISTOR
DESCRIPTION
Vehicles equipped with a power liftgate utilize a
chime/thermistor assembly. The chime/thermistor
assembly is a small capacitor shaped electrical com-
ponent mounted to the rear license plate lamp hous-
ing assembly (Fig. 4) , located just above the license
plate. The chime portion of the assembly controls the
audible chime sound heard at the rear of the vehicle
when the power liftgate is in motion. The thermistor
portion of the assembly is a temperature sensor, used
by the power liftgate module.
The chime/thermistor assembly is a serviceable
component. Consult your MoparŸ parts catalog for a
specific part number.
OPERATION
The chime/thermistor assembly performs two dif-
ferent functions for the power liftgate system. First,
the chime portion provides an audible chime sound
which is controlled by the power liftgate module. The
chime/thermistor assembly is hardwired to the power
liftgate module. Second the thermistor provides a
outside temperature reading by way of a resistance
reading (V- ohms) supplied to the power liftgate
module. As temperature increases the resistance
reading (V- ohms) increases, as temperature
decreases the resistance reading (V- ohms)
decreases.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.
(2) Remove the rear light bar assembly from the
vehicle. Refer to Body for the procedure.
(3) Using your hands, grasp the light bar at its
sides next to thermistor/chime assembly and gently
pull the two sides of the light bar apart until the
thermistor/chime assembly can be removed.
INSTALLATION
(1) Gently pull the two sides of the light bar apart
until the thermistor/chime assembly can be installed.
(2) Install the rear light bar assembly on the vehi-
cle. Refer to the Body section of the service manual
for the procedure.
(3) Connect the negative battery cable.
ENGAGE ACTUATOR
DESCRIPTION
Vehicles equipped with a power liftgate utilize a
power liftgate engage actuator (Fig. 5). The 12 volt
engage actuator provides the engagement and disen-
gagement of the liftgate gear motor to the lift gear by
way of an over center link, activated by a lever.

The engage actuator is a serviceable component
and cannot be repaired, if found to be faulty it must
be replaced.
OPERATION
The engage actuators normal position is disen-
gaged. When a power liftgate open or close command
is generated from any of the command switches, the
power liftgate control module signals the engage
actuator to move its lever to the engaged position.
This engages the gear motor to the lift gear, so when
the motor turns the lift gate moves upward or down-
wards depending on its current position.
During a manual liftgate open or close cycle the
engage actuator is disengaged, allowing unrestricted
liftgate movement.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.
(2) Remove the left rear D-pillar trim from the
vehicle. Refer to Body for the procedure.
(3) Using your hand manually engage the actuator
link rod, this must be done to access one of the
engage actuator retaining screws.
(4) Remove the two engage actuator retaining
screws (Fig. 6).
(5) Disconnect the engage actuator electrical con-
nector and remove the engage actuator from the
vehicle.
INSTALLATION
(1) Position the engage actuator and connect the
engage actuator electrical connector.
(2) Install the two engage actuator retaining
screws.
(3) Manually disengage the actuator.
(4) Install the left rear D-pillar trim on the vehi-
cle. Refer to Body for the procedure.
(5) Connect the negative battery cable.
(6) Using an appropriate scan tool, check and
erase any power liftgate control module diagnostic
trouble codes.
(7) Verify power liftgate system and engage actua-
tor operation. Cycle the power liftgate through one
complete open and close cycle.
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.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.
(2) Open the liftgate and remove the liftgate trim
panel. Refer to the Body section of the service man-
ual for the procedure.

FULL OPEN SWITCH
DESCRIPTION
Vehicles equipped with a power liftgate utilize a
full open switch. This switch is located on the gear
motor housing (Fig. 8) and is used to signal the
power liftgate module when the liftgate is in the full
open position. Two wires are used from the full open
switch contacts to the gear motor assemblies main
electrical connector.
The full open switch is a serviceable component.
Consult your Mopar parts catalog for a specific part
number.
OPERATION
When the power liftgate reaches the full open posi-
tion, the gear motor housing mounted full open

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. 9) 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 theactuator. Consult your Mopar parts catalog for spe-
cific part numbers.
OPERATION
On the power cinch/release latch, the latch
mounted actuator provides the torque required to
close the power liftgate from the secondary to the pri-
mary closed and latched position. On the power
cinch/release latch and the power release only latch,
the actuator releases the liftgate from the primary
closed and latched position to the fully unlatched and
movable position.

LATCH ACTUATOR
DESCRIPTION
Vehicles equipped with a power liftgate utilize a
power cinch latch or power release latch (Fig. 10).
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

LIFTGATE MOTOR
DESCRIPTION
Vehicles equipped with a power liftgate, utilize a
liftgate gear/motor assembly (Fig. 11). The gear
motor assembly consists of a DC motor, hall effect
sensor, engage actuator, full open switch, lift gear,
aluminum housing, drive gears and wire harness.
The gears and motor portion of the assembly pro-
vides the power and torque required to open or close
the liftgate under the worst case conditions. The hall
effect sensor is used to provide the liftgate control
module with a speed reading, which is used to mon-itor the resistance of liftgate travel. This speed read-
ing also allows the power liftgate control module to
detect obstructions and move the liftgate accordingly.
The engage actuator is used to toggle between power
open/close mode and full manual mode when desired.
The full open switch is used to let the power liftgate
control module know when the liftgate is approach-
ing the full open position.
Serviceable components of the power liftgate gear/
motor assembly are the complete gear/motor assem-
bly, motor and wire harness, lift gear and control rod,
engage actuator, full open switch and the transverse
bracket. Refer to additional information in this group
for more component details.
OPERATION
With the push of a power liftgate command switch
(liftgate closed), the power liftgate control module
will signal the latch assembly to release the door
from its primary closed and latched position to the
released and movable position. The liftgate motor-
mounted engage actuator then engages the liftgate
motor assembly, which moves the liftgate into the
open position. The liftgate motor provides the torque
and power to move the door to its full open or closed
position(Refer to 8 - ELECTRICAL/POWER DOORS -
OPERATION) for additional information.
REMOVAL
The power liftgate gear/motor assembly is serviced
in two ways: the complete gear/motor assembly, or
the motor, aluminum housing, drive gears and wire
harness assembly. To perform this service, use the
following procedure to remove the gear/motor assem-
bly from the vehicle. Then refer to the other proce-

LIFT GEAR & LINK ROD
DESCRIPTION
Vehicles equipped with a power liftgate utilize a
lift gear and rod assembly. This lift gear and rod
assembly are located in the left rear of the vehicle
and are visible without removing the D-pillar trim
(Fig. 12). The lift gear provides the leverage to move
the liftgate from the closed to the open position. The
lift gear attaches to a bearing on the gear motor
assembly with four bolts. On the outboard side of thelift gear are riveted on teeth, which mesh with the
gear motor assembly drive gears during a open or
close operation. The rod assembly is a steel shaft,
equipped with two spherical rod ends which attaches
the lift gear to the liftgate.
The lift gear and rod assembly are serviceable com-
ponents. Consult your MoparŸ parts catalog for a

PINCH SENSOR
DESCRIPTION
Vehicles equipped with a power liftgate utilize two
pinch sensors, one is located on each side of the lift-
gate (Fig. 14). These sensors look like weather-strips,
however they consist of pieces of electrically conduc-
tive rubber (tapeswitch), wires, resistor, double sided
tape, and a plastic carrier. They are used to indicate
an obstruction during a power close cycle.
OPERATION
During a power liftgate close cycle, if either of the
two conductive rubber strips (tapeswitch) of thepinch sensor come in contact with an obstacle, the
pinch sensor circuit is completed. This tells the
power liftgate control module that a obstruction is
felt. The control module will stop the liftgate imme-
diately and return it to the full open position.
