HVAC Issues 1997 2500 Truck

So, I've searched but not found my issue. Since my fan blows air like it should, hot or cool but it only comes out at the bottom no matter where I place the position switch, is it an actuator or my control panel. I get no clicking or any noise whatsoever. Switch feels the same but I'm guessing it will no matter what. I was hoping it would die on defrost since it's now getting to be "winter" here in the balmy south of Tennessee...

For safety reasons they are supposed to default to defrost, mode door could be stuck/broken or the gears in the actuator could be stuck/broken.

Mine is stuck somewhere in the middle so I’ve only got a little air blowing out all the vents, sometimes if I kick the bottom of the hvac box, the door will move to the desired position lol

There are many threads on this. My experience is to do it right, you need to remove the box, clean everything, find the problem then test and reinstall it.

Thanks. I just removed it and moved the rod. I don't have the time to take it apart right now. I'll order one when I order the power steering lines that now appear to be leaking. Plus, its 9 degrees, but feels like -9 here in Tennessee so it's way down on my list of stuff I need to do before tomorrow..
