Why does your Air conditioning go from vent to defrost when accelerating?

Mainly because you don't need a fogged up windshield if you are driving fast. Seriously, the defroster setting is where most autos go to if there is a problem with vacuum. If nothing worked in your dash controls, the one thing you would still need would be the defroster, so that is the default setting. Now, when you accelerate fast, the throttle is wide open, and there is no vacuum, or it is very low, so with low vacuum the control reverts back to defrost. It would be the same as if you un hooked a vacuum line and did not feed your dash controls, you would only have defrost.
