[h=2]Actuator Recalibration[/h]When replacing the HVAC control module it will be necessary to allow the HVAC control module to perform a calibration process. When installing the HVAC control module be sure to perform the following:
Note: Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result.

1. Place the ignition switch to the OFF position.
   
2. Disconnect the scan tool.
   
3. Install the HVAC control module.
   
4. Connect all previously disconnected components.
   
5. Ignition ON.
   
6. Wait 40 s for the HVAC control module to self-calibrate.
   
7. Verify that no DTCs have set as current DTCs.
   

When replacing the HVAC actuator it will be necessary to allow the HVAC control module to perform a calibration process. When installing the HVAC actuator be sure to perform one of the following:

[h=4]Preferred Method (with Scan Tool)[/h]

1. Note: Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result.
   
   
2. Clear all DTCs.
   
3. Place the ignition switch in the OFF position.
   
4. Install the HVAC actuator.
   
5. Connect all previously disconnected components.
   
6. Start the vehicle.
   
7. With the scan tool, initiate the HVAC Actuators Learn feature of the Remote Heater and Air Conditioning Control Module Configuration/Reset Functions menu.
   
8. Verify that no DTCs have set as current DTCs.
   

[h=4]Alternate Method (without Scan Tool)[/h]

1. Note: Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result.
   
   
2. Clear all DTCs.
   
3. Place the ignition switch to the OFF position.
   
4. Install the HVAC actuator.
   
5. Connect all previously disconnected components.
   
6. Remove the HVAC control module fuse for a minimum of 10 s.
   
7. Install the HVAC control module fuse.
   
8. Ignition ON.
   
9. Wait 40 s for the HVAC control module to self-calibrate.
   
10. Verify that no DTCs have set as current DTCs.
