When the vacuum lines that control the vents get disconnected the HVAC system automatically defaults to defrost vents only for safety reasons so that you can always see out the windshield. Look for a disconnected vacuum line.

there is vacumm lines running along the heater box.. the most common place for it to go off is the vacumm supply line in the passenger footwell.. also check the connections at the vacumm motors on the box itself.
