Climate Control Assembly

Removal

1. Disconnect the battery ground cable(s).

2. Remove the trim strip above the heater control (18549) and glove compartment area.

3. Remove the two screws that attach the center finish panel to the instrument panel (04320) to gain access to the four screws that attach the heater control to the instrument panel. Refer to Section 01-12.

4. Remove the four screws. Then, pull the heater control far enough through the opening in the panel to allow disengagement of the electrical connectors for the heater blower motor switch (18578) and control illumination lamps, etc.

5. Disconnect the electrical harness connectors from the heater blower motor switch and illumination connectors on the heater control.

6. Remove the connector from the stowage notch in the heater outlet floor duct (18C433). Disconnect the vacuum hose harness (19C827) from the connector.

7. Pull heater control away from instrument panel far enough to install Temperature Control Cable Removal Tool T94P-18532-A on the A/C temperature cable (19988) connector on the backside of the heater control.

8. Using a small flat-bladed screwdriver, lift the third locking tab as indicated in the following illustration and remove the A/C temperature cable by pulling straight back.

Installation

1. Pull the A/C temperature cable through the opening in the instrument panel for a distance of approximately 200mm (8 inches).

2. Hold the heater control near the instrument panel. Attach the A/C temperature cable to the gear rack.

3. Place the heater control back to the position it occupies for insertion into its opening. Snap the bullet end into the bracket. Be sure that the end is firmly seated.

4. Connect the wire harness to the heater blower motor switch and control illumination lamp. Attach the vacuum hose harness to the heater control and to the plenum harness.

5. Attach the connector to the stowage notch in the heater outlet floor duct.

6. Position the heater control into its opening while being careful that the vacuum hose harness and electrical harness are properly stowed and install four retaining screws.

7. Install center finish trim panel with two attaching screws.

8. Install the trim strip above the heater control and glove compartment area after installing the two retaining screws.

9. NOTE: When the battery (10655) has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module (PCM) (12A650) relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.

   Connect the battery ground cable(s).

10. Check the system for proper operation.
