Actuator Recalibration

The HVAC control module will relearn the actuator limits whenever power is disconnected and re-connected to the module.

Use the following steps to perform the calibration update:

 1. Turn OFF the ignition.
 2. Remove the battery positive voltage circuit fuse of the HVAC Control Module or disconnect the battery negative cable.

Important: The scan tool must be disconnected from the vehicle to properly perform the calibration procedure. If a scan tool is connected before this procedure is completed, then new calibration values will not be stored.

Important: Failure to wait 60 seconds will not allow the HVAC control module sufficient time to clear the old calibration values.

 3. Wait 60 seconds.
 4. Install the fuse or reconnect the battery
 5. Turn ON the ignition.
 6. Wait 60 seconds before touching any buttons on the HVAC control. You may hear the actuators cycling as they recalibrate.
