Installation Procedure





1. Install new air inlet, drain, and plumbing seals to the HVAC module.





2. Carefully install the HVAC module to the vehicle in the following SEQUENCE.

Important: Ensure that the cut-outs on the dashmat are properly aligned so that the air inlet, drain, and plumbing seals are seated directly against the dash panel and not the dashmat.

2.1. Check the dashmat (1) for proper alignment to the dash panel; align if necessary.
The opening in the dashmat for the HVAC module drain should be aligned so that the drain opening in the dash panel is approximately centered in the dash mat opening; allowing ample room for the module drain seal (2) to fully seat against the dash panel.
2.2. ALIGN the heater core joint fitting, the condenser joint fitting, the HVAC module drain and the HVAC module studs to the corresponding openings on the dash panel.
2.3. INSERT the LH stud into the dash panel FIRST, then the module drain, then the RH stud.
2.4. Install the HVAC module LH retaining bolt to the I/P upper support beam module net locating hole (3).
2.5. Install the HVAC module RH retaining bolt to the I/P upper support beam.

Tighten
Tighten the HVAC module retaining bolts to 10 N.m (89 lb in).

Important: To prevent possible water leaks or wind/road noise from entering the vehicle passenger compartment, DO NOT reuse the old HVAC module retaining and sealing nuts.

2.6. Install the HVAC module new retaining and sealing nuts to the dash panel. Reposition the refrigerant lines slightly, if necessary.

Tighten
Tighten the HVAC module retaining and sealing nuts to 10 N.m (89 lb in).





3. Install and align the windshield defroster duct to the HVAC module opening and the lip upper support beam.
4. Install the windshield defroster duct LH retaining screw (net locating hole).

15. Install the RH side window defogger outlet duct - lower.
15.1. Use a twisting motion to secure the defogger outlet duct - lower to the defogger outlet duct - upper, then to the windshield defroster duct.
15.2. Install the defogger outlet duct - lower retaining tabs to the passenger SIR bracket.





16. Position and align the LH floor air outlet duct - rear to the HVAC module, then push firmly and evenly to secure the duct.





17. Install the LH floor air outlet duct to the HVAC module.
18. Install the floor air outlet duct retaining screws.

Tighten
Tighten the floor air outlet duct retaining screws to 1.6 N.m (14 lb in).

19. Install the I/P center support bracket and the ignition switch housing bracket.





20. Connect the electrical connector to the temperature valve electric actuator.
21. Connect the Daytime running Lights (DRL) sensor electrical connector to the LH side of the windshield defroster duct, if equipped.





22. Install the LH side window defogger outlet duct - lower.
22.1. Use a twisting motion to secure the defogger outlet duct - lower to the defogger outlet duct - upper, then to the windshield defroster duct.
22.2. Install the push-in retainer.





23. Install the instrument panel cluster (IPC) into position.
24. Install the IPC to steering column bracket retaining screws.
