Does anyone know if it is possible to test the A/C compressor relay? I'm having an intermittant probelm on very hot days during which the "tip switch" ie snowflake won't start the a/c compressor. I'm trying to figure out if the switch is bad, or relay, or something that I haven't thought of? Maybe low freon, etc.?

Anybody had a reason to suspect that they're a/c on off switch is malfunctioning?

Your advice will be appreciated!
