Default A/C air blows out of top and bottom only....help

I know it is a vacuum leak (so I guess) and was curious to see if anybody knew where to start.

The air (no matter what setting) only blows out of the top and bottom. Where should I start and if anybody has had this problem what did you do to fix it?

THanks

behind the heater controls are some small rubber hoses, make sure they are all hooked up, it is easiest to take out the heater controls and start at the back, then about a foot down is a joiner thing, make sure they are all there too, if they are all on then its the small line on the passenger side firewall in the engine compartment, right above where the A/C lines go in.
make sure its hooked to a vacuum source.

before you go crawling up under the dash there is a vaccum tree in the engine compartment on the passenger side. It has 3 hoses going to it. You need to cmake sure there isnt a hole in the hose coming from the small vaccum tree to the big 5 hoses vaccum tree. This was my friends problem bc he couldnt switch controls either
