Hi. I recently tried every conceivable combination on the climate control, with engine on and off. I note air speed increases and decreases, temperature goes up and down, but the air doesn't change where it is coming from.

With the engine off, while trying pressing buttons on the climate control, I hear small noises in the dash like servos quietly going on or off, but there is no change in where the air comes from. Note: with a flashlight I can see the center vent flaps are in a half-way position, neither fully open or closed.
