Your problem is most likely that the AC system is low on refrigerant. Your Explorer takes R-134A refrigerant which is available over the counter. It's not a very difficult process to add refrigerant but if your uncomfortable doing it yourself, most service centers will service your AC for under $100 assuming no leaks are detected. Best of luck on your AC problem.

SOURCE: climate control system only blow air out defrost vent

there is a good chance that you blend air door is stuck closed over your heater core and therefore not allowing the heat to flow, also your door that opens and close your direction of flow from the floor ,das,vent and defrost.your going to have to remove the lower cowling of the dash on the passenger side analso some of the center dash to actually check to see if the cable,servo motors. are acuating the doors.the issue could be just a stuck door or a misaligned cable or that it came off. that falls under the mechanical side of probabilities. electrical would most likely be a faulty selector switch or a servo motor

Check your vacuum pump located on the right side fenderwell. see if its running. Check the vacuum hose at the hubs for leaks or damage. repair if damaged. check for other vacuum leaks such as the grey hose going to the heater control valve.
