Could be a few things. AC system prob, low refrigerant, temp blend door, etc.... Is the clutch engaging on the compressor?

I had a simmilar problem, and that was a leak in the lines, so it only worked for a few days, then it was hot again, a pressure test of the system gave the spot where the leak was and the line had to be replaced ! otherwise I agree with Mike to solve the problem
