CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system. 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 system.

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 with A/C shown in illustrations. RHD and heater-only models similar.




1. Install the upper half of the HVAC housing (4) onto the lower half of the HVAC housing (6).

2. Install the eleven screws and one clip (5) that secure the two halves of the HVAC housing together. Tighten the screws to 2.2 Nm (20 in lbs.).

NOTE: If a foam insulator for the A/C evaporator or its tubes is deformed or damaged, it must be replaced.

3. Install the A/C evaporator and tubes (7) into the lower half of the HVAC housing. Make sure that the evaporator drain within the HVAC housing is clean and unrestricted and that the insulators around the A/C evaporator and its tubes are properly installed.

4. Install the flange (2) to the front of the HVAC housing.

5. Install the two screws (3) that secure the flange to the HVAC housing. Tighten the screws to 2.2 Nm (20 in. lbs.).

NOTE: If the foam seal for the flange is deformed or damaged, it must be replaced.

6. Install the foam seal (1) onto the flange.




7. Position the blower motor (4) into the HVAC housing (2).

8. Install the three screws (3) that secure the blower motor to the HVAC housing. Tighten the screws to 2 Nm (17 in. lbs.).

9. Engage the blower motor wire harness connector (1) to the retainer located on the HVAC housing.




10. Install the air inlet housing (3) onto the HVAC housing (1).

11. Install the air distribution housing (2) onto the HVAC housing.

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

12. Install the HVAC housing assembly.

13. 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. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
