One of the apparatus could be broken that directs the air toward the face. This is probably a cheap and inexpensive fix. It would be best to ask a friend if they can fix it before taking it to a mechanic.

The heater fan ONLY blows the air, it does not make the temperature of that air. Your heater temperature controls how hot the air is. Adjust your heater temperature for hotter or cooler air.
The vacuum line that goes to the defroster is probably disconnected, possibly on the fire wall.
Try your thermostat
Figured it out...the blend door actuator was not fully seated when I replaced it.
Actually, the AC is always blowing cold air. Its just that sometimes your nerves can't feel it because your body is used to it.
