Hi. Hooked the gauges up again today and got 65psi on the low side, 100psi on the high side. I understand that pressures don't mean a whole lot with a variable compressor system but just wanted to see what they were today. Feeling around the pipework I feel only mildly warm at the compressor outlet ...

One quick question... Wouldn't low refrigerant level result in low system pressure, either on the the low pressure side or just overall? Would it be worth evacuating, checking for leaks and refilling and take it from there?

Thank you for the very detailed reply. I appreciate you taking the time to write that. Clearly I have some more studying to do! My initial, basic level thinking was that the exv must be stuck open, allowing the high pressure to bleed through to the low pressure side hence the pressure readings I was...

Hi. New to this forum and seeking some help to diagnose a problem. I just bought a 2010 Chevy Aveo and the AC is not blowing cold air. I borrowed the gauge kit from AutoZone and got the following readings with the AC running and the compressor clutch engaged: low side pressure around 90psi, high sid...
