Can you see the inner part of compressor clutch turning? The two main possibilities are:
➀ clutch air gap too much and not engaging. (Click yes, spin no)
➁ variable displacement compressor stuck at zero.
Since revving makes a difference, I think it's 2. You get higher pressure than me once it kicks on.
