Hi guys,
My 2003 vibe suddenly started blowing hot air today. I got out my trusty r134a can and hose w/gauge to go fill it up. I hooked it up and no pressure reading at all on the gauge. Thinking the system was empty I tried turning the valve and letting it draw the refrigerant in but nothing got sucked in. I thought the can was empty after opening the valve on the hose, so I took it off and I learned the hard way that it wasn't empty. Fortunately had safety glasses on. I used a screwdriver to see if there was pressure in the system by pushing down on the schrader valve on the low pressure side and got a lot of nice pressurized hiss coming out, so not sure why the refrigerant wasn't going in. Compressor seems to be kicking on, I can hear it and it causes the idle to adjust. Any ideas what might cause the A/C to suddenly stop working? Thanks for your help!
