firts check the vacuum line from the intake to the HVAC system for cracks/disconnected. the system will default to defrost/floor when no vacuum is present. If you have vacuum, then the actuator for the defrost mode is stuck.

check vacuum control valve assy under right hand dash. Check for 12 volts on purple wire if there remove control vlve assy and take off cover . inspect printed circuit to valve body conections.
