ENGAGE ACTUATOR
DESCRIPTION
The 12 volt engage actuator (Fig. 3) provides the
engagement and disengagement 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 inoperative 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 battery negative
cable.
(2) Remove the left rear D-pillar trim from the
vehicle,
(Refer
to
23
-
BODY/INTERIOR/LEFT
D-PILLAR TRIM PANEL - REMOVAL).
(3) 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. 4).
(5) Disconnect the engage actuator electrical con-
nector and remove the engage actuator from the
vehicle.

EXTERIOR HANDLE SWITCH
DESCRIPTION
The exterior handle switch is an electronic release
switch mounted to the rear license plate lamp hous-
ing assembly, located just above the license plate.
This switch controls the power liftgate release func-
tion and is also capable of reversing the power lift-
gate when it is in motion. A full power open cycle
cannot be performed using this switch, only one of
the power open command switches (key fob and over-
head console mounted) can be used to perform a full
power open cycle. The exterior handle switch is a ser-
viceable component.
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 BCM then
sends a signal to the power liftgate control module
via
the
Programmable
Communication
Interface
(PCI) data bus circuit. The power liftgate control
module then sends a signal 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 battery negative
cable.
(2) Open the liftgate and remove the liftgate trim
panel, (Refer to 23 - BODY/DECKLID/HATCH/LIFT-
GATE/TAILGATE/TRIM PANEL - REMOVAL).
(3) Remove the rear lamp bar assembly from the
vehicle.
(4) Locate the two wires going to the exterior han-
dle switch. Cut the tie strap and trace the wires to
the large electrical connector and back the wires out
of the large connector and through the grommet.
Take care to mark the location of the wire ter-
minals in relation to the large connector so
that they are positioned in the appropriate cav-
ities upon switch installation.
(5) Depress the two exterior handle switch retain-
ing tabs and roll the switch out of the light bar
assembly (Fig. 5).
INSTALLATION
(1) Install the handle switch in the light bar
assembly (Fig. 6).
(2) Locate the two wires going to the exterior han-
dle switch. Install the wires through the grommet
and in the large connector. Secure with a tie strap.
NOTE: Be certain wires are reinstalled in the correct
wire cavities. Failure to do so could result in dam-
age to the handle switch. Refer to the appropriate
wiring information for complete circuit schematic or
connector pin-out information.
(3) Install the rear light bar.
(4) Install the liftgate trim panel, (Refer to 23 -
BODY/DECKLID/HATCH/LIFTGATE/TAILGATE/
TRIM PANEL - INSTALLATION).
(5) Connect the battery negative cable.
(6) Using an appropriate scan tool, check any
erase any power liftgate control module diagnostic
trouble codes.

(7) Verify power liftgate system and handle switch
operation. Cycle the power liftgate through one com-
plete open and close cycle, this will allow the power
liftgate control module to relearn its cycle with the
new components.
FULL OPEN SWITCH
DESCRIPTION
The full open switch is located on the gear motor
housing (Fig. 7) and is used to signal the power lift-
gate control module when the power 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.
OPERATION
When the power liftgate reaches the full open posi-
tion, the gear motor housing mounted full open
switch electrical contacts close. This sends a ground
signal to the power liftgate control module, telling
the module that the liftgate has reached the full open
position.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the lift gear and link rod assembly
from the vehicle (Refer to 8 - ELECTRICAL/POWER
DOORS/CONTROL ROD - REMOVAL).
(3) Cut the two wires leading to the full open
switch or back the wires out of the electrical connec-
tor.
(4) Remove the full open switch retaining screw
and remove the full open switch from the gear motor
housing assembly.
INSTALLATION
(1) Perform a wiring repair on the full open switch
wires following the approved procedure in the Wiring
section of the service manual. Or install new termi-
nals on the wire ends and reinstall in the main lift-
gate motor electrical connector.
(2) Position and install the full open switch retain-
ing screw.
(3) Install the power liftgate lift gear and link rod
assembly.
(Refer

DOORS/CONTROL ROD - INSTALLATION)
(4) Connect the battery negative cable.
(5) Using an appropriate scan tool, check any
erase any power liftgate control module diagnostic
trouble codes.
(6) Verify power liftgate system and full open
switch operation. Cycle the power liftgate through
one complete open and close cycle, this will allow the
power liftgate control module to relearn its cycle with
the new components.

LATCH
DESCRIPTION
The power cinch/release 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 vehicles,
this latch is designed to perform a power release
only. The power cinch and release capability is
accomplished by an actuator mounted to the leading
edge of the latch assembly. The latch is located in the
lower center of the power liftgate assembly (Fig. 8)
and contains integral pawl and ratchet switches. The
ratchet switch also acts as a liftgate ajar switch. The
power latch assembly can be serviced as a complete
assembly, latch without actuator or just the actuator.
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.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Open the liftgate and remove the liftgate trim
panel, (Refer to 23 - BODY/DECKLID/HATCH/LIFT-
GATE/TAILGATE/TRIM PANEL - REMOVAL).
(3) Disconnect the power latch electrical connector
(Fig. 9).
(4) Remove the power latch retaining bolts.
(5) Disconnect the liftgate lock cylinder link rod
(Fig. 9) from the key cylinder or latch assembly. To
disconnect from latch, rotate the plastic retaining clip
90 ° to unsnap clip from linkrod. Then pull link rod
straight out of latch arm.
(6) Remove the power latch from the vehicle.
INSTALLATION
(1) Position the power latch in the vehicle.
(2) Connect the liftgate lock cylinder link rod (Fig.
10) on the cinch latch assembly. Rotate the plastic
retaining clip 90 ° to lock retaining clip onto the link
rod.
(3) Connect the link rod on the lock cylinder.
(4) Install three new power latch retaining bolts.
Torque to 10 N·m (90 in. lbs.).
(5) Connect the power latch electrical connector
and secure push pin retainers.
(6) Connect the battery negative cable.
