vacuum hose cam unhooked from the back of the intake most likely. reach back there and check (will be on the very back of the intake, in the center... pointed towards the passenger side)
There is a Tee on the passenger side by the A/C lines, make sure none of the lines have come loose or the Tee is not cracked/broken.

Your vacuum line is disconnected behind the intake manifold. Trace the small vacuum line (by the HVAC box by the PCM) that goes to the back of the intake manifold and make sure its connected to the vacuum supply. This line supplies vacuum to the HVAC controls. If you are missing vacuum, it blows to the floor and defrost as a default.
