NOTE: While holding the A/C-heater control in the
installation position, verify that the control cables
are not twisted.
(4) Turn the mode control knob on the A/C-heater
control to the nine-o-clock position.
(5) Turn the upper mode door lever counter-clock-
wise until it reaches its stop and install the cable
into the retainer in this position (arrow).
(6) Turn the lower mode door lever clockwise until
it reaches its stop and install the cable into the
retainer in this position (arrow).
(7) Operate the mode control knob and verify that
the mode door cables are properly adjusted.
(8) Install the A/C-heater control and the two
retaining screws. Tighten the screws to 2 N·m (17 in.
lbs.).
(9) Install the center section of the instrument
panel (Refer to 23 - BODY/INSTRUMENT PANEL/
INSTRUMENT PANEL CENTER BEZEL - INSTAL-
LATION).
(10) Reconnect the battery negative cable.

RECIRCULATION DOOR
ACTUATOR
DESCRIPTION
This vehicle uses a two-position vacuum operated
recirculation door actuator to move the recirculation
door. Vacuum supply to the recirculation door actua-
tor is controlled by an integral electronic control sole-
noid. The recirculation door actuator is mounted on
the outboard side of the ventilation housing above
the blower motor in the engine compartment.
OPERATION
The recirculation door actuator uses engine vac-
uum, which is controlled by an integral electrical
solenoid. The electrical solenoid is connected to the
ATC control through the vehicle electrical system by
a dedicated two-wire lead and connector. The output
shaft of the recirculation door actuator is keyed to a
pivot shaft, which is keyed to the recirculation door
shaft. The recirculation door actuator can move the
recirculation door in two directions.
The recirculation door actuator is controlled by an
electrical switch that is integral to the heater-A/C
control. When the rotary-type mode control knob is
moved to the recirculation position, a signal is sent to
the electrical solenoid within the recirculation door
actuator. This signal causes the solenoid to open a
port to engine vacuum which pulls the output shaft
into the actuator, which moves the recirculation door.
