You could possibly have a small vacuum leak somewhere. Then again, vacuum motors were never designed for reaction speed...

I drive on the right side, what's wrong with you?

even if its off, when i turn it directly to the a/c vents it starts at the defrost, then moves to the floor then to the a/c vents

Vacuum motor control systems are slow to react sometimes. A lack of proper vacuum supply (due to a leak) could make it worse. There is also the possibility that the peice on the back of your knob is cracked (blue plastic that slips over the posts). Check the back of your knobs and check for vacuum leaks. I justed noticed you said over a minute, so something isn't right. Those are the two things I would check first. One common place for a vacuum leak is the rubber elbow on the end of the plastic line at the lower portion of the intake manifold near the rear. That boot can get oil on it and swell, creating a loose fit.
