1. Recover the refrigerant from the A/C system. Refer to Refrigerant Recovery and Recharging .
2. Drain the cooling system. Refer to Cooling System Draining and Filling in Engine Cooling.
3. Remove the wiper motor module assembly. Refer to Windshield Wiper System Module Replacement in Body and Accessories.

Important: The defroster door must be closed to allow clearance during defroster duct removal.

4. Set the HVAC controls in the vent setting to close the defroster door.
5. Remove the blower motor. Refer to Blower Motor Replacement .



6. Disconnect the electrical connector from the blower motor resistor.



7. Disconnect the electrical connector from the evaporator temperature sensor.
8. Disconnect all of the HVAC electrical actuator connectors.
9. Remove the I/P carrier. Refer to Instrument Panel Carrier Replacement in Instrument Panel, Gages and Console.



10. Remove the evaporator outlet tube nut.
11. Disconnect the evaporator outlet and inlet tubes from the TXV.
12. Disconnect the heater inlet hose from the heater core. Refer to Heater Inlet Hose Replacement .
13. Disconnect the heater outlet hose from the heater core. Refer to Heater Outlet Hose Replacement .



14. Remove the HVAC module to dash panel sound barrier nuts.
15. Remove the HVAC module assembly from the cowl.

Important: Ensure proper alignment of the HVAC module assembly and HVAC module drain through the cowl.

1. Install the HVAC module assembly to the cowl.



2. Install the HVAC module assembly to dash panel sound barrier nuts.

Do not tighten the HVAC module assembly nuts at this time.

3. Install the heater outlet hose to the heater core. Refer to Heater Outlet Hose Replacement .
4. Install the heater inlet hose to the heater core. Refer to Heater Inlet Hose Replacement .
5. Install new sealing washers to the evaporator inlet and outlet tubes. Refer to Sealing Washer Replacement .
6. Connect the evaporator inlet tube to the evaporator outlet tube.



7. Connect the evaporator inlet and outlet tubes to the TXV.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

8. Install the evaporator outlet tube nut at the TXV.
