1. Install the A/C evaporator (2) into the HVAC housing (3). Make sure that the evaporator drain within the HVAC housing is clean and unrestricted and that the insulator (1) around the A/C evaporator is properly positioned.





2. Install the two halves of the HVAC housing (1 and 3) together and install the eleven retaining screws (2). Tighten the screws to 1.2 Nm (10 in lbs.).





3. Install the evaporator temperature sensor (5) to the HVAC housing (1). Make sure the retaining tabs are fully engaged.

4. Install the blower motor resistor or power module (depending on application) (4) to the HVAC housing. Make sure the retaining tabs are fully engaged.

5. Install the blower motor (3) to the HVAC housing and install the retaining screw. Make sure the blower motor locking feature is fully engaged and tighten the screw to 1.2 Nm (10 in. lbs.).

6. Install the HVAC wire harness (2) and connect it to the blower motor, blower motor resistor or power module (depending on application) and the evaporator temperature sensor.





7. Install the air inlet housing (2) onto the HVAC housing (1) HVAC Housing - Installation.

8. Install the air distribution housing (3) onto the HVAC housing HVAC Housing - Installation.

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