You need to look at high side pressure as well but I'll make a guess anyway.

85psi is about right for 80oF if your compressor is not working. I would anticipate you'd see the same on the high side and if so, you compressor is not functioning. The absolute value of the pressure will change depending on the outside temperature.

The spinning you see is normal - there's an electric clutch inside. My guess is that your compressor clutch has failed.

Somewhere in INPA is a toggle to activate the compressor clutch.
Maybe: Body > Air Conditioning > Activate > Digital Output > Air Conditioning Compressor. Going from memory here, could be wrong. Anyway, google it. Activate it and you should hear a "click". No click probably means bad compressor clutch (but wiring issue could be the problem too)
