when loss of power to hvac unit sometime the hvac actuators need to be recalibrated. possibly try to remove the hvac control fuse under the driver rear middle seat for a minute and reinstall, turn key on and do not touch any hvac module buttons for another minute to allow actuator to recalibrate then recheck to see if repaired. if that does not fix it you will need to take it to a gm dealer to get it recalibrated with the tech 2 scan tool.
