2005 Toyota Corolla - Heat will not blow out of the floor vents

What is your question?

Air/Heat will blow out of the top vents(defrost) and middle vents, but air will not blow out of the floor vents. The cables are connected from the control knob to the side of something located on the wall between the engine and inside of the car and they move when the knob is turned. (sorry I am new to this site and didn't put what kind of car it was and couldn't figure out how to add that info.)
