The ac on my 2006 1.8 is just blowing hot air. Had it recharged this morning but it’s still the same. 500gr was taken out and 580gr put back in. Pressure test was good, clutch engages and compressor is working when ac is on, but it just blows hot. I didn’t pay for it though but the mechanic said he had no idea what the fault was. Has anyone experienced this before?
