Why doesn't my A/C work?

What is your question?

My A/C in my 2000 Camry starts for a few seconds when I press the button. Rpms increase for a few seconds, then go back down and a light on the AC begins blinking. Before it stopped working, the evap box drain became clogged and it flooded. It is not the magnetic clutch relay. I have already tested that. How do I diagnose? What seems to make the problem better or worse? nothing How long have you had this problem? a few months
