Now, if one of the car air condition system hose or seal was ruptured it can cause a very rapid leak of refrigerant from the air condition system, thus making its function to reduce suddenly.

However, there is also another cause of this kind of problem, the car air condition electrical problem, since the blower suddenly stop blowing cold air from the car air condition vents, the possibility is that a wire or a switch on car air condition system has been shorted which causes the circuit breaker to pop, this can cause a sudden reduction of car air condition performance such as no cold air is blown out into car passenger compartment.

Another possibilities but is very rare to happen is having a compressor related problem, more specifically the belt that drives the compressor could be slipping or much worst it is broken or the compressor clutch might not be engaging.
