It sounds like the climate control unit has failed. A leak in the system (no or low refrigerant) would also cause the A/C to blow hot air, but the compressor would still be operational.

Still, do an A/C system check for leaks first to get that ruled out. I don't know of a good way to check the climate control unit, but they have been notorious for failure.
