Default HVAC position changes on throttle

Whenever I hit the throttle on my car, the HVAC position seems to go to the floor. Once I sit idle (or brake) the vents up top start working again. The car runs completely fine otherwise. This happens in every setting; heat, a/c, whatever. It's also happened since I got the car a few years ago with 45k miles on it. 105k now.
