AC will come on only if the car is coming from a COLD start

What is your question?

04 Acura TL, AC will come on only if the car is coming from a COLD start, ie it has not been on for a few hours. Also when I go to turn it off while it is running and try to get it back on most of the time it will not come back on and I can tell the compressor clutch is not engaging as I do not hear anything but the engine does rev slightly, freon full,shop says ac clutch is gone
