When the car air conditioner blowing hot air this only indicates that the air conditioning either has electrical problem or has major leak on the system. If the a/c system has electrical problem it suddenly stop blowing cold air, instead the car air conditioning system blows hot air. Usually an electrical problem is triggered by a short circuit on the system either the wire or the a/c switch that causes the circuit breaker to become busted. In that case there is a sudden stoppage of cold air that comes out the a/c vents.
Likewise when there is a major leak of refrigerant on the system, there is a sudden stop of blowing of cold air on you're a/c vents causing car ac blowing hot air. Refrigerant is the one responsible in carrying the heat from your car compartment into the outside so that the compartment will becomes cooler. For some reasons if the air conditioning hoses or seals are ruptured or damage, the refrigerant will rapidly escape the system thus resulting to sudden reduction of cold air that comes out the a/c vents.
There are other possibilities that causes this kind of problem, however this possibilities is not commonly encountered, which is a compressor related problem. Usually the compressor belt is slipping or damaged. Also it might be possible that the compressor clutch is not engaging. As I have said about the cause of a/c problem, these are possibilities that are not commonly encountered but can also be considered.
If you encountered this kind of problem, the first thing to look at is the very obvious, check the engine compartment and look for any ruptured or damage compressor belt. Next is to look at the circuit breaker or a busted fuse, reset the breaker or replace the fuse, bring the vehicle to a reputable auto repair shop and have a mechanic to inspect the electrical system of your vehicle.
