Vents are uaually operated by vacuum. Chances are, you have a vacuum leak at the directional valve or at the back of the air controller itself. All of these are in or under the dash. Good luck.

It should blow through the floor vents. Modern vehicles generally use movable baffles in there HVAC systems, to direct air flow where the controls indicate. If the controls allow airflow to the floor, but nothing flows out, there is a malfunction between the control switch and the actuator that directs the flow.
