I had an issue where the A/C would not turn on for the past few days...really odd....checked pressures today, first step in all issues.

Do these look right for r134a?

Outside temperature today is 57F. This was at idle ~700rpm. First pic is static pressure of course.
What is the correct static pressure for a W124?





If the issue returns, where should be the first place I look? Klima relay maybe?
