Heat won't turn off no matter what?

I removed the glovebox and checked out the blend door actuator, and the door opens in the off position, and max AC position, but stays closed all the time. Even if I turn the dial all the way to cool. I don't know what this means. But what I do know, is that when I turn the heat on, it's very intense. Turning the hot/cold dial does absolutely nothing. And if I put the selector dial to A/C it blows heat, but Max A/C blows cold air. Could there be a leak in the ducts somewhere? What do you think it is?
