module pulls the voltage on one side of the motor
connection high and the other connection low, the
rear mode door will move in one direction. When the
module reverses the polarity of the voltage to the
motor, the rear mode door moves in the opposite
direction. When the module makes the voltage to
both connections high or both connections low, the
mode door stops and will not move. These same
motor connections also provide a feedback signal to
the front heater-A/C control module. This feedback
signal allows the module to monitor the operation
and relative positions of the rear mode door actuator
and the mode door. The front heater-A/C control mod-
ule learns the rear mode door stop positions during
the calibration procedure and will store a Diagnostic
Trouble Code (DTC) for any problems it detects in
the mode door actuator circuits.
The rear mode door actuator can be diagnosed
using a DRBIII
t scan tool. Refer to Body Diagnostic
Procedures for more information. The rear mode door
actuator cannot be adjusted or repaired and, if dam-
aged or faulty, it must be replaced.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the right quarter trim panel and right
D-pillar trim panel from the quarter inner panel
(Refer to 23 - BODY/INTERIOR/QUARTER TRIM
PANEL - REMOVAL).
(3) Remove the two screws that secure the top of
the quarter trim panel attaching bracket to the quar-
ter inner panel.
(4) Remove the screw that secures the back of the
rear HVAC housing to the right D-pillar.
(5) Remove the screw that secures the front of the
rear HVAC housing to the right quarter inner panel.
(6) Carefully pull the top of the rear HVAC hous-
ing away from the right quarter inner panel far
enough to reach between the rear HVAC housing and
the quarter inner panel to access the rear mode door
actuator (Fig. 12).
(7) Remove the two screws that secure the mode
door actuator to the rear HVAC housing.
(8) Pull the mode door actuator away from the
rear HVAC housing far enough to disengage the
actuator output shaft from the mode door linkage.
(9) Raise the mode door actuator far enough to
access and disconnect the rear HVAC wire harness
connector from the actuator
(10) Remove the rear mode door actuator from
between the rear HVAC housing and the quarter
inner panel.
INSTALLATION
(1) Position the mode door actuator between the
rear HVAC housing and the quarter inner panel.
(2) Reconnect the rear HVAC wire harness connec-
tor to the rear mode door actuator.
(3) Position the rear mode door actuator onto the
rear HVAC housing. If necessary, rotate the actuator
slightly to align the splines on the actuator output
shaft with those in the mode door linkage.
(4) Install the two screws that secure the rear
mode door actuator to the rear HVAC housing.
Tighten the screws to 2 N·m (17 in. lbs.).
(5) Push the top of the rear HVAC housing back
into position against the right quarter inner panel.
(6) Install the screw that secures the front of the
rear HVAC housing to the right quarter inner panel.
Tighten the screw to 11 N·m (97 in. lbs.).
(7) Install the screw that secures the back of the
rear HVAC housing to the right D-pillar. Tighten the
screw to 11 N·m (97 in. lbs.).
(8) Install the two screws that secure the top of
the quarter trim panel attaching bracket to the quar-
ter inner panel. Tighten the screws to 2 N·m (17 in.
lbs.).
(9) Reinstall the right quarter trim panel and
right D-pillar trim panel onto the quarter inner
panel (Refer to 23 - BODY/INTERIOR/QUARTER
TRIM PANEL - INSTALLATION).
(10) Reconnect the battery negative cable.
(11) Perform the heater-A/C control calibration
procedure (Refer to 24 - HEATING & AIR CONDI-
