The lvl select door is vacuum operated. I'm not sure where the vacuum block is located on this year, but if u look in a manual it will help.
You should see the vacuum lines under the hood on the firewall. There is a black housing that they connect into. Replacing that housing should fix the problem unless you have a cracked Vacuum line. You can get a cheapy T shaped line at most parts stores.

the middle vents only supply air from the ac unit using a separate in dash fan. the floor and defrost vents come only from the heater
Why Heater vents are usually placed near the floor?
Warm(er) air rises - if vents were high up there would be little circulation without fans.
Why heat blows out vents only not defrost or floor?
Most likely a bad or disconnected vacuum hose to the defrost/floor selector in the heater ducting.

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.

Check the following.......... 1. Vacuum leak, broken vacuum line or disconnected vacuum line. 2. A/C - heater inside car door operation.. 3. A/C - heater controller..
What does it mean if you have steam coming out of your vents when you have the heat on?
It means you have a leaky heater core. You may also find the front passenger floor wet with engine coolant.
