A/C not working and its HOT in AZ!!!! HELP!! My A/C was working just fine then I was out driving the other day and it slowly started getting warmer and warmer(thought maybe it was just really hot out and couldnt keep up) and then what do ya know...no ac. I tried recharging it but when I hook up the hose the guage shows 100 and it wont recieve the charge. When I disconnect the hose theres the (shhh) noise as if there was presure. I've tried it with the A/C on high and also with the engine off. Any other ideas???? Need help guys its freakin hot down here in AZ!!!!!

About the compressor....im not hearing it kick on but its not as loud as my envoys so im not real sure...its actually pretty quiet...sooo i dunno. Is there a no **** way to tell other than hearing it?

You have to look at the compressor to see if the clutch is spinning, not just the pulley itself. When you recharge, the a/c has to be set to maximum fan speed setting and cold setting, don't do it when the car is off. If the clutch isn't spinning after you've recharged it a bit, it needs some refrigerant to get moving, the compressor is a goner. You also may have a leak if the compressor clutch does spin. Check your hoses, I know that mines near the firewall is cracked which is why I'm losing my charge for the moment

Prob your pressure switch on the accumulator. This cycles the compresser clutch on and off, according to pressure to keep the evap. from icing up. Easy trick is to unplug the pressure switch and use a small wire to jump it out (on the side with wires) if clutch engages and you are reading a 100 psi its the switch.
