I had my a/c fixed less than a year ago. When the sun is down and the temp is under 80 degrees it blows cold air. Once it's really hot outside and sunny the air blows mild/warm. I have no idea what causes this so i would love some help. Thank you.

You are correct most auto AC systems are functionally the same ,except for the controls.


You need to put a set of gauges on the system--the high side should be 15bar,the low side 2-3 bar-----wada you get!
