ACTUATOR-MODE DOOR
DESCRIPTION
The heating-A/C system uses two vacuum operated
mode door actuators (1) to control the movement of
the mode-air doors within the HVAC housing.
When vacuum is supplied by the A/C-heater control to
the vacuum connector (3) on one side of the defrost/
floor actuator or the panel door actuator, the actuator
rod is pulled into the actuator, which moves the mode
door lever and mode-air door in one direction. When
vacuum is supplied by the A/C-heater control to the
other side of the actuator, the rod moves the mode-air
door in the other direction.
The mode door actuators are retained to the HVAC
housing by an integral mounting provision (2) and can
be accessed for service from under the driver side of
the instrument panel.
The mode door actuators cannot be adjusted or
repaired and, if faulty or damaged, they must be
replaced.
REMOVAL
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering
wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the
battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before
performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to
take the proper precautions could result in an accidental airbag deployment and possible personal injury or
death.
1. Disconnect and isolate the negative battery cable.
2. Remove the knee blocker from the driver side of
the instrument panel (Refer to 23 - BODY/INSTRU-
MENT PANEL/BLOCKER-KNEE - REMOVAL).
3. Disconnect the vacuum harness connectors (1 and
3) from the panel door actuator (2) or the floor/de-
frost door actuator (4) located on the driver side of
the HVAC housing (5) as required.

4. Insert a trim stick C-4755 or equivalent (2) into the
latch hole of the HVAC housing actuator mount(s)
(1). Gently pry the actuator latch (3) away from the
HVAC housing mount while pulling firmly outward
on the actuator and disconnect the actuator from
the HVAC housing.
5. Rotate and tilt the actuator(s) as required to disen-
gage the actuator link from the mode door lever
and remove the actuator from the vehicle.
INSTALLATION
1. Install the panel door actuator (2) or the floor/de-
frost door actuator (4) as required, by engaging the
hole in the end of the actuator link to the hooked
pin on the end of the door lever located on the
driver side of the HVAC housing (5).
2. Install the actuator(s) onto the actuator mount(s).
3. Connect the vacuum harness connectors (1 and 3)
to the actuators as required.
4. Install the knee blocker (Refer to 23 - BODY/IN-
STRUMENT PANEL/BLOCKER-KNEE - INSTALLA-
TION).
5. Reconnect the negative battery cable.

ACTUATOR-RECIRCULATION DOOR
DESCRIPTION
The heating-A/C system uses a vacuum operated
recirculation door actuator (1) to control the movement
of the recirculation-air door within the HVAC air inlet
housing.
When vacuum is supplied by the A/C-heater control to
the vacuum connector (3) of the recirculation door
actuator, the actuator linkage is pulled into the actua-
tor, which moves the recirculation door lever and recir-
culation-air door to the Recirculation position. The
recirculation door actuator is spring loaded, so when
vacuum is released from the actuator, the linkage
moves the recirculation-air door back to its static posi-
tion (fresh air).
The recirculation door actuator is retained to the
HVAC air inlet housing by an integral mounting provi-
sion (2) and can be accessed for service by removing
the instrument panel.
The recirculation door actuator cannot be adjusted or
repaired and, if faulty or damaged, it must be
replaced.
REMOVAL
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering
wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the
battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before
performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to
take the proper precautions could result in an accidental airbag deployment and possible personal injury or
death.
1. Disconnect and isolate the negative battery cable.
2. Remove the instrument panel from the vehicle
(Refer to 23 - BODY/INSTRUMENT PANEL/IN-
STRUMENT PANEL ASSEMBLY - REMOVAL).
3. Disconnect the vacuum line harness connector
from the recirculation door actuator (1).
4. Release the latch that secures the recirculation
door actuator mount (2) to the top of the HVAC
housing (3) and disengage the actuator from the
housing.
5. Disconnect the recirculation door actuator from the
recirculation door lever (4) and remove the actuator
from the vehicle.

INSTALLATION
1. Connect the recirculation door actuator (1) to the
recirculation door lever (4).
2. Align the recirculation door actuator mount (2) to
the stanchion on the HVAC housing (3), and press
the actuator onto the stanchion firmly to fully
engage the latch.
3. Connect the vacuum harness connector to the
recirculation door actuator.
4. Install the instrument panel (Refer to 23 - BODY/
INSTRUMENT
PANEL/INSTRUMENT
PANEL
ASSEMBLY - INSTALLATION).
5. Reconnect the battery negative cable.
