Welcome to 2CarPros.
There is a component there called a blend air door actuator. It is an electric motor that opens and closes a door. The door, blend air door, is what determines if you get heat or AC entering the vehicle. Now, exactly what he did, I can't say. However, I am going to provide directions for replacing both the blend air door and the actuator. Hopefully this will help you. The attached pictures correlate with the directions and yes, it is located under the dash.
First, here is link that shows how in general one is replaced:

If you look at the last picture, it shows the door I am referring to. My guess is somehow he turned it to the correct position for AC and used the hanger to hold it. The best thing to do would be just replace the actuator so you don't have this problem.
Let me know if this helps or if you have other questions.
Take care,
Joe
