theres 3 or 4 vacuum lines that run to the heater box and pulling vacuum on certain ones opens and closes the flaps inside of it. Default mode (no vacuum) is defrost mode.
Sounds like the lines off the back of the controls arent connected correctly

Vacuum lines! Or maybe the little reserve canister under the hood is n/g.
