The little vents (or flaps) inside the heater system are stuck, broken, lost power (they're vacuum motors).
Why would the ac and heater blow air through the defroster or the dashboard vents but not through the floor vents.?
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.

Why does your 2003 Honda Accord heater blow cold air through the defroster vents and warm air through the dash vents?
This means that you have either an issue with a vacuum line or one of the a/c - heater doors behind the dash is not working correctly and you need to start off at the a/c - heater controller to check that all positions are working...........
What makes a 1998 expedition smells like a fishy odor coming from vents?
usually the air conditioner drain tube is plugged up, if water doesn.t run out freely when the air conditioner or defroster is on, chances are the evaporator core drain is blocked and the water in the box has begun to smell. The alternate possibility is that someone who doesn't like you has put fish guts in your heater intake.

That is actually how the vehicle was designed. If you look at the selector knob for the vents you'll notice that the arrows pointing down and for the windshield are white and the vents for the dash are blue. Basically, you can defrost and warm your feet and that's it
