(7) Remove liquid line mounting clamp fastener
located near service port (Fig. 27).
(8) Disconnect liquid line fastener at filter-drier.
Remove liquid line from vehicle. Cap off all fittings if
reusing to prevent moisture from entering system.
INSTALLATION
For installation, reverse the above procedures.
Torque liquid line fasteners as follows: TXV and con-
denser: 20.3 N·m (15 ft. lbs.). Filter-drier line fasten-
ers 13.6 N·m (10 ft. lbs.). Plastic bracket and screws:
6.8 N·m (5 ft. lbs.).
MODE DOOR ACTUATOR
The mode door actuator is an electric motor. It
mechanically positions the A/C unit panel/bi-level
door and the floor/defrost door. This actuator con-
tains a feedback strip which allows the computer
control to know the exact position of the mode door
at all times. The mode door actuator is not service-
able and must be replaced if found to be defective.
The mode door actuator is located on the lower left
side of the HVAC unit housing (Fig. 28).
REMOVAL
(1) Open hood and disconnect the negative battery
cable remote terminal from the remote battery post
(Fig. 13).
(2) Remove left and right underpanel ducts.
(3) Remove floor console.
(4) Remove center floor heat adaptor duct.
(5) Remove rear seat heat forward adaptor duct.
(6) Loosen center support bracket and pry rear-
ward to gain access to the actuator.
(7) Remove actuator retaining screws. Then pull
actuator straight down. Upon removal, note the shaft
position of the actuator, because the shaft on this
motor is keyed. When installing new actuator, its
shaft must be positioned in the same location.
(8) Remove electrical connection on actuator.
INSTALLATION
For installation, reverse the above procedures.
RECIRCULATION DOOR ACTUATOR
The recirculation door actuator is located on the
right side of the heater housing (Fig. 28).
The recirculation door actuator is an electric motor.
It mechanically positions the recirculation door in
either the open or closed position. The recirculation
door actuator does not have a feedback signal. The
outside Air/Recirc door actuator is not serviceable
and must be replaced if found to be defective.
