Check the vents fuse and/or relay in the underhood fuse/relay center (near battery). Also, check the inside fuse box for any fuse related to the climate control system. If a fuse or relay is bad the climate control will not switch from defrost to vents to heat.
Is the air mainly coming out of the heater ducts (bottom of dash)?
If fuses/relays are good, try this:
Underneath the dash on the passengers' side (on the heater/ac box) there is a actuator for the vents. It's a "cigarette box sized" black box with about 4-5 wire plugged into it. It has a round, hollow, metal piece protruding through it slightly. When you move the selector to vent or defrost or floor, you should be able to see the metal piece rotate, thus moving the vent to the desired position. If this doesn't happen and the fuses are good, let me know and I'll get you the step-by-step procedures.
