You probably have a vacuum leak on the passenger side. its a small plastic hose some times they come unpluged from the engine. or brake.

Can you hear anything moving in heater when you move the switch to other settings? If not then the blend door is not moving to redirect air flow. There is three things that could cause this, 1 the control switch is bad or 2 the blend door acturator is bad, and 3 linkage for the door has come unhooked or broke, most likely its #1 or #2. First you need to find the blend door acturator and test light the wires to it, there should be 3, 1 hot with key on 2 only hot with switch moved, and 3 ground. If you got power from wires than the acturator motor is bad, if no power switch is bad.

SOURCE: Heat and AC vent problem.
most likley you have a vaccume leak somewhere but also the linkage to the door that that directs the air flow may be in a bind. another possability is the hvac controlls. hope this helps

There is only one door. Air flows through the AC evaporator and the blend door diverts some or all of the flow through the heater core. For heat, the compressor is off under electric control and the non-refrigerated air is diverted through the heater core. The door is on a vertical axis and can swing to any position based on random corner turns, fan speed, mode, etc.
