30. Install the screws that secure the blend door actuator mounting bracket to the air distribution housing. Tighten
the screws to 2 N·m (17 in. lbs.).
31. Position the blend door actuator (7) onto the air distribution housing. If necessary, rotate the actuator slightly to
align the splines on the actuator output shaft with those on the blend-air door linkage (Refer to 24 - HEATING
& AIR CONDITIONING/CONTROLS/ACTUATOR-BLEND DOOR - INSTALLATION).
32. Install the screws (2) that secure the blend door and mode door actuators to the air distribution housing. Tighten
the screws to 2 N·m (17 in. lbs.).
33. Install the air distribution housing onto the HVAC housing (Refer to 24 - HEATING & AIR CONDITIONING/DIS-
TRIBUTION/HOUSING-HVAC - HOUSING-AIR DISTRIBUTION - INSTALLATION).
HOUSING-AIR INLET
NOTE: The air inlet housing must be removed from HVAC housing and disassembled for service of the
recirculation-air door.
NOTE: LHD model shown. RHD model similar.
1. Position the recirculation-air door (4) into the air
inlet housing (1).
CAUTION: Make sure that the recirculation-air
door pivot shaft is properly seated in the pivot
seats located on the air inlet housing.
2. Install the recirculation door actuator (3) onto the
air inlet housing. If necessary, rotate the actuator
slightly to align the splines on the actuator output
shaft with those on the recirculation door pivot
shaft (Refer to 24 - HEATING & AIR CONDITION-
ING/CONTROLS/ACTUATOR-RECIRCULATION
DOOR - INSTALLATION).
3. Install the three screws (2) that secure the recircu-
lation door actuator to the air inlet housing. Tighten
the screws to 2 N·m (17 in. lbs.).

1. If removed, install the foam seal (2) over the tap-
ping block of the A/C evaporator (1). If the seal is
deformed or damaged, it must be replaced.
2. Install the A/C evaporator into the lower half of the
HVAC housing (3). Make sure that the evaporator
drain within the HVAC housing is clean and unre-
stricted and that the insulator around the A/C evap-
orator is properly installed.
3. Install the upper half of the HVAC housing (3) onto
the lower half of the HVAC housing (4).
4. Install the screws (2) that secure the two halves of
the HVAC housing together. Tighten the screws to
2.2 N·m (20 in lbs.).
5. Install the HVAC wiring harness (1). Make sure the
harness is routed through all wiring retainers.

6. Remove the tape or plugs from the evaporator tube
fittings and all of the expansion valve ports.
7. Lubricate new rubber O-ring seals with clean refrig-
erant oil and install them on the evaporator tube fit-
tings. Use only the specified O-rings as they are
made of a special material for the R-134a system.
Use only refrigerant oil of the type recommended
for the A/C compressor in the vehicle.
8. Install the A/C expansion valve (2) onto the evapo-
rator tube tapping block located within the foam
seal (3).
9. Install the two bolts (1) that secure the A/C expan-
sion valve to the evaporator tube tapping block.
Tighten the bolts to 11 N·m (97 in. lbs.).
10. Install the evaporator temperature sensor (2)
(Refer to 24 - HEATING & AIR CONDITIONING/
CONTROLS/EVAPORATOR
TEMPERATURE
SENSOR - INSTALLATION).
11. Install the blower motor resistor or power module
(3), depending on application (Refer to 24 - HEAT-
ING & AIR CONDITIONING/CONTROLS/RESIS-

12. Install the blower motor (4) (Refer to 24 - HEAT-
ING & AIR CONDITIONING/DISTRIBUTION/MO-
TOR-BLOWER - INSTALLATION).
13. Connect the HVAC wire harness (1) to the evap-
orator temperature sensor, blower motor resistor
or power module (depending on application) and
the blower motor.
14. Install the two HVAC wire harness retainers (5)
onto the blower motor.
15. Install the heater core tubes (4) and the flange (2)
to the front of the HVAC housing (3).
16. Install the two screws (1) that secure the flange to
the HVAC housing. Tighten the screws to 2.2 N·m
(20 in. lbs.).

removed from the HVAC housing and disassem-
bled for service of the mode-air and blend-air
doors.
1. Position the air distribution housing (1) into the
vehicle.
2. Install the air distribution housing onto the rear of
the HVAC housing (2) by inserting the tabs on the
bottom of the distribution housing into the slots
located on the bottom of the HVAC housing and
tipping the distribution housing forward until it is
