No Cold Air

[gator1]

Need advice on A/C problem on my 1999 GS400, 170k miles. All A/C and Heating controls are working fine, the green light on the A/C button is on except the air that I get is not cold. I had the freon checked, it was evacuated and replaced but this did not solve the problem. Compressor sounds like it is switching on but I am not sure, belt is moving fine and compressor is definately not locked up. Any thoughts are appreciated.
