weird problem?

Hey guys,
Question.... How come when I hit the gas on the the road does my A/C go through the defroster vents, and when I let off, it comes the through the front vents :(

I honestly have no idea?

You've got a vacuum leak. Check your vacuum ball (should be in your bumper on the passenger side) and make sure it's not craked and inspect the vacuum line coming out of it. That should fix your problem.
