2018 Chrvy Express 2500 6cyl
AC stopped working, no leaks, found it was a bad high side pressure switch, ac worked for about 2hrs and stopped again. Could this possible be a bad switch I just replaced or another issue. Not sure what else to look at. Without the clutch engaging I am not able to temp test the condenser like you have shown to test for a blockage.
Thanks in advance!

Update, took the pressure switch off and replaced it. Still not working.

Is there sufficient static pressure in the AC system to permit the compressor to engage?
A professional-grade bidirectional scan tool is really needed to diagnose the electronics in those computer-controlled HVAC systems.
