Check your right pressure, check your ac belt its ok and good, check your compressor condition, tested with gator wires connecting one pole to a ground or negative terminal on battery and the other pole to a positive pole on battery, then disconnect the wire harness to your compressor and touch one pin with the negative pole and the other pin with the positive pole and check if the compressor activates the ac cluthc on the front of compressor ac pulley... something else could be but this its the basic check :)

It is very possible you have developed a leak within the AC system. The blower motor is indepoendent of your AC. The blower pushes air thru the condensor (which when you have your air on becomes cold from the freon your compressor pushes) If the freon has leaked the air will not cool. Being an AC system you'll need to take it to a shop. Special tools and training are required to work with freon.
I hope this may have helped you,
Tom

You are probably low on freon. Pop your hood and see if the compressor keeps clikcing every 5-10 seconds. If it is then you are low on freon. The compressor is on the front of the engine and will have a pulley on it being spun by a belt. you will be able to hear it without seeing it.

Air conditiong vents on the passenger side blow colder than on the drivers side


Try adding just a tad of freon,if this does not help,then the actuator motor for the directional door is not moving all the way open ,it is in the dash and the dash would have to be removed to replace it.
