Why would the air conditioner only blow cold air on the floor but not through the vents?

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.

There are heater doors on the heat blower box that direct the path of the heat. Apparently the heater door to the floor vents is stuck closed.

The flap that directs sir to the selected vents is jammed or broken...or the switch that controls it is.

Warm(er) air rises - if vents were high up there would be little circulation without fans.

Heating vents should be located near the floor since hot air rises. If the heating vents are located near the ceiling the heat would stay there and not warm the room.
