Wow.... it could be several things. The fact that the compressor engages tells me there is enough freon in the system to engage it. Thus, you should get at least a slight bit of cool air. Also, the AC may be working find, but there could be a problem with the blend air door stopping the cold air from entering the vehicle. Okay, one last try. On the compressor, there are two steel lines that run from it to rubber lines. One will be slightly larger in diameter than the other. That is the low pressure side. Run the AC for about 10 minutes, turn the engine off, and then feel both of the steel lines. One should be hot and the other cold. PLEASE don't burn yourself. Just touch quickly to see if you can tell if at least one is cold.

Let me know what you find.
