Could be a couple of reasons:
You can check your pressure levels in the system, if they are low, you have a leak or need to pump some freon (or whatever they are using nowadays) into it.
If that helps, it means the issue was that. If it stops working after a month or two, you have a leak in your system.
If your pressure levels are good, it might be the compressor. Check the electrical connections, maybe something shook loose. If those are fine, it might be the compressor itself. I'd give that to check to a mechanic.
If none of the above, maybe your alternator or your car battery isn't giving it enough juice to power the system.
Good luck.
I've also seen A/C systems refuse to turn on from an engine overheating. They were driving it every day with the "H" pegged and didn't think anything of it.
