WHY WOULD AIR NOT BLOW OUT DEFROST AND MIDDLE VENTS, BUT ONLY ON THE FLOOR. I CAN HEAR THE CLICKING DOOR OPEN AND SHUT SOUNDS LIKE IT IS WORKING, BUT FAINT AIR ONLY COMES OUT, BUT ROARING ON THE FLOOR AREA. ANY IDEAS WHAT TO DO?

I believe you are dealing with a vacuum leak. The vent doors are actuated by vacuum. If the vacuum is weak or leaking, this is what happens.

Check under the dash for leaks or damaged vacuum hoses.

Let me know what you find.
