Exclamation wj intermittent heat/air condition help?

i have a 2004 grand cherokee 4.7L. Have been getting issues with the heat/air conditioning and was hoping someone had some suggestions. As im accelerating i loose air flow through the vents (both heat and air conditioning) The air will still flow through the floor though. I can still hear the blower so i know its not that. Once i let off the throttle the air flow returns. Happens with both heat and air conditioning. Thinking it has something to do with a vacuum problem. Any suggestions????

Are you getting air flow on the floor AND defroster?
