There are several reasons that may explain why your air conditioning system is blowing warm instead of cool air.
The first possibility is that there is a refrigerant leak. The leak may be found in the evaporator, condenser or hose in which case you should bring your car to a mechanic to be repaired.
Another reason that your air conditioner may not be blowing cool air is because the compressor has gone bad. The compressor pressurizes the refrigerant and pumps it throughout the AC's necessary components. Because everything revolves around the compressor, if it is faulty then the air conditioning will not work correctly. Usually there will be a loud noise when you attempt to turn on your air conditioner if the compressor is broken.
Finally, another problem that may be occurring with your air conditioning system is that there is a clogged orifice tube. This is located between the condenser in the front of the radiator, and the evaporator in the passenger compartment. If there is an obstruction in the tube then it will stop the refrigerant from reaching the evaporator, causing your system to blow warm air.
