A/C stopped working CGT - need advice

Hello,

The compressor seems to stay on as long as I leave it on for ,  but
haven't left it on long enough for the radiator fan to kick in for fear
of burning out the pump if I am out of freon.  Site glass I have not
checked yet (would be a smart idea though), and the evaporator does not
get cold at all from what I can feel.

Any ideas?
