i checked alot of the pages but didnt see anything on this, i mean similars but not this.. anyways, my compressor i dont think is kicking on, and im sure it is because of the low refridgerant, at autozone when i checked the pressure it was damn near the red (with ac on max cool) but that was 2 weeks ago when the ac blew hot air, NOW all it does is hiss no matter what setting i put it on, i have touched nothing, it just quit... is this still due to a LEAK???
