From what little information you gave, it sounds to me like it (the A/C) is operating normally but your car is overheating. The fan should NOT come on and run almost anytime the car is moving - mine doesn't, even in 95F or so weather - unless, of course, I'm sitting still for a time. (Ok, fine, the fan runs, but not at any speed you can hear it running, if I'm moving at all.)
Are you getting any warning lights on the dash when the A/C cuts out? If so, what lights are coming on?
The radiator fan runs as soon as the AC is switched on, that is my understanding. So if it doesn’t then something is wrong. You can hear the AC compressor switch on and off.
