'01 Astro interior air ventilation system - 3/31/2008 9:33:17 AM

hey, does anyone know anything about the 2001 astro passenger van (LS 4.3 AWL) air vent system? a shuttle driver of an astro van told me to turn on DEFROST at HIGH setting to recirculate interior air (without drawing in outside air). then, i was unable to get any dash vents or other vents to work! even air conditioning would only blow onto windshield! no matter what variations done of the control panel dial, only air blows on windshield through the windshield vents! is this a fuse?
i heard the sound of a baffle or vane audibly turning/closing upon running defrost at HIGH. did some directional baffle/vane close or otherwise reposition, not allowing air to resume its normal pathway?
opinions are welcome, since i am about to take it to my local mechanic, and he initially did not know the answer to this strange occurrence.
thanks, SDCA_Paul

sounds like the vacuum source for the hvac system is either broken, leaking, or has come unplugged. With out vacuum, the system default to the windshield so you can still see while your driving
