Make sure your fan is coming on, you should hear it come on when you turn on the A/C or defrost. The most common problem for that symptom is the fan relay burns out, and the A/C comes on strong but then overheats quickly making the pressure in the condenser get too high and the pressure cycling switch automatically turns off the A/C. The condenser then cools and the process starts over. If you can locate your radiator fan fuse and relay, which will be in the fuse box under the hood, you can rule out the relay by pulling one of the same size from another system that isn't important like the fog lamps(if equipped). As long as you verify that the fan is NOT working, you would try this relay swap test as long as the fuse is still good. I work for a Ford dealer as a technician, if you brought your vehicle in for service for an A/C or heater concern and your still having problems with it. You can bring it back in for a "recheck" or "repeat" repair and they will have no right to charge you again... If I worked on someones car, and the problem came back after they left, I would seriously want to know because I care about my work and care about my name as a master technician. Just remember, you do not have to pay for repeat repairs... EVER!!
I hope this info helps!~subyguru~

I think your problem is the head unit that selects where the air comes out ie. Face, floor, defrost, or hi-level face and floor. If that's not working then it will not let you switch location that you want the air to come out.

You can test both of them once you have it apart. I have given you instruction below. Please follow them as injury could result.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
CAUTION: Stay clear of the blower motor and resistor block (Hot). Do not operate the blower motor with the resistor block removed.
Disconnect and isolate the battery negative cable.
Remove the glove box from the instrument panel (Refer to 23 - BODY/INSTRUMENT PANEL/GLOVE BOX - REMOVAL).
Pull out the lock on the blower motor resistor wire harness connector to unlock the connector latch (Blower Motor Resistor Block- Typical).
Depress the latch on the blower motor resistor wire harness connector and disconnect the connector from the resistor.
Remove the two screws that secure the blower motor resistor block to the HVAC housing.
Remove the resistor block from the HVAC housing.

the hvac selector switch in the dash may be the problem.You need to remove the switch and look at the connector on the back of switch,see if there are any burnt wires at the connector or switch.It's all electronic and the switches have been known to burn out on this and other model.
