If it is, failure to fix it can blow the AC system. On long trip air conditioner quit blowing cold air. Leaking evaporator detected by electronic leak detector.
Hi Froggy, I think you were properly using the gages. I have checked multiple parts of the AC system, temperature sensors, Air Temp Actuators, and refrigerant pressure.
My pressures are similar to yours except the high side is substantially higher than .
Having issues with the GM RAC compressor on the suburban.

I hate these things, they suck! Chevy Suburban Ac problem - Duration: 1:28. No air conditioning , but the fuses and relay to the compressor seem to be OK.
Check the circuits once confirming the system is fully charged with R134a.
A quick check shows the compressor is ok so the problem must be elsewhere. A bad viscous clutch was not pulling enough air through the condensor, causing the pressure to build too much on the high side. The evaporator is located on the inside of the firewall.
This took care of my intermittent compressor issue.
