Question A/C keeps changing vents or blowing out the floor when I accelerate

1995 Trans Am. A/C keeps changing from dash vents to floor or going off when I accelerate. What's going on??

Sounds like a vacuum issue to me - you can probably find the answer here: http://shbox.com/1/4th_gen_tech2.html#HVAC_vacuum

Problem solved. Found broken vacuum line way up over the vacuum canister..added rubber hose to fix. Vents work better and idles a little smoother. Thanks for the info.
