How can I Diagnose ac problem? Compressor will not engage. AC blows hot air. AC system has no leaks-is fully charged. I have been told everything from "Climate control switch" to a bad compressor. I am a senior citizen on a fixed income and can not afford to let people practice until they fix the problem. Please help.
