CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system Refrigerant Oil Level. Failure to properly adjust the refrigerant oil level will prevent the A/C system from operating as designed and can cause serious A/C compressor damage.

NOTE: When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant systemRefrigerant Oil Level.

NOTE: If the A/C evaporator is being replaced, add 60 milliliters (2 fluid ounces) of refrigerant oil to the refrigerant system. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.

NOTE: LHD model shown in illustrations. RHD model similar.





1. If removed, install the foam seal (3) onto the condensate drain located at the bottom of the HVAC housing (2).
2. Install the air deflector vane (1) into the lower half of the HVAC housing. Make sure the retainers are fully engaged.




NOTE: Make sure the rubber seal for the evaporator tubes and tapping block is properly positioned in the HVAC housing opening.

3. If removed, install the rubber seal (4) over the evaporator tubes and tapping block (5).

NOTE: Make sure that the foam insulator around the A/C evaporator is properly positioned within the HVAC housing.

4. Carefully install the A/C evaporator (1) and foam insulator (2) into the lower half of the HVAC housing (3).




5. Install the two halves of the HVAC housing (2 and 6) together and engage the four plastic retaining tabs (4). Make sure the retaining tabs are fully engaged.

NOTE: Be sure to install the screws that secure the two halves of the HVAC housing together located at the bottom of the HVAC housing.

6. Install the seven screws (5) and two metal clips (3) that secure the two halves of the HVAC housing together. Tighten the screws to 1.2 Nm (10 in lbs.). Make sure the metal clips are fully engaged to the housing halves.
7. Install the foam seal (1) onto the front of the two HVAC housing halves.




8. Install the evaporator temperature sensor (1) into the front of the HVAC housing (2). Make sure the sensor is fully engaged to the housing.




9. Position the blower motor (4) into the bottom of the HVAC housing (2) and install the three retaining screws (3). Tighten the screws to 1.2 Nm (10 in. lbs.).
10. Position the blower motor resistor (5) into the HVAC housing and install the two retaining screws (1). Tighten the screws to 1.2 Nm (10 in. lbs.).




11. Install the air inlet housing (3) onto the HVAC housing (2) HVAC Housing - Installation.
12. Install the air distribution housing (1) onto the HVAC housing HVAC Housing - Installation.
13. Install the passenger side lower front floor duct Floor Ducts - Installation.

NOTE: If the heater core is being replaced, flush the cooling system Service and Repair.

14. Install the HVAC housing assembly HVAC Housing - Installation.
15. If the A/C evaporator is being replaced, add 60 milliliters (2 fluid ounces) of refrigerant oil to the refrigerant system. When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system Refrigerant Oil Level. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
