I have the same noise problem- I "THINK" it might be the clutch. AC works great- haven't had to add freon in 19 years now- but it is getting very noisy.

Does anyone have a reference for the proper high and low side pressures for the Air Conditioner in a 2000 Eurovan?
The system was flushed and replaced in 2017 (Compressor, expansion valve, receiver drier).
The AC performance is great, and is quiet when it starts up, but it makes weird noises after running for a while.
I just purchased a manifold gauge set and took some readings:
Lo Hi Status
-------------------------
85 85 70F ambient, engine off
30 130 AC on, fan on speed 1
34 155 AC on, fan on speed 4
42 195 AC on, blocking grille with cardboard to reduce airflow
Sources on the internet are saying the Low pressure is fine, but the High pressure might be a bit low, and this could suggest it's low on R134a, but I'm not sure I have the right pressures: I believe the Sanden 1214 compressor is a variable displacement compressor.
