Heat/ Air Controls

Hello,
I have a 2005 Chevy Express van w/ 5.3L AWD. The heater/ air controls do not mix the air. It is either full hot or full cold no in between. What do I need to replace to fix this and does it require taking out the whole dash? Thanks.

The heat in that vehicle is controlled by a blend door that regulates heated air flow. it is operated by an electric motor/actuator. The problem can be that the actuator is stripped or inoperative or the door itself could be damaged. This is what needs to be determined by examining the actuator and see if it is responding to heat change commands or not.
The listed labor time to change the actuator is less than half an hour.
