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.

Where is a heater actuator on a 2003 Tahoe rear heater?

under the plastic trim at the passenger side in the cargo area. After removing lots of plastic trim with mostly push-clips and 2 or 3 screws, you'll see the heater/AC assembly. On it, you'll see 2 identical motors. One controls a flapper door to send air to the ceiling or the floor (the forward one), and the other controls a flapper door that sends air over the evaporator or the heater core.
