A/C

[300zman]

A/C works fine until the car warms ups, then will not cool down. All A/C parts are new, fully charged with R-12. The car is a 1993 Q45. I might be thinking something to do with the climate control?

Do you have any numbers on how cold it gets and a what outside temperatures outside. My best guess is that it doesn't have the properly amount of freon on it, too much or not enough.

Do the test on the attached image, to get an idea of the temperatures you are getting. Ignore jumping ambient sensor.
