There are two ways to recalibrate the HVAC doors, one is to connect a scantool to communicate with the HVAC module and perform a actuator recalibrate or if you don't have a scantool you could disconnect the battery for 10 min and reconnect which will also relearn the HVAC doors..

You will need a scantool to retrieve the codes from the HVAC unit and to perform a calibration test...
If you have a scantool then communicate with the HVAC module and retrieve the DTC's, also look in misc and relearn the doors..
