The first thing I would do is see if you are getting a signal to the single wire on the compressor clutch, when the ac is turned on. If you are and you say the ac isn't working, then the compressor has failed and you won't need to go any further.

Most likely low or out of freon, the system will not engage the ac compressor if there's low pressure in your lines.
