V50 AC not cooling

My 2006 Volvo V50 diesel has an AC issue. It's stopped cooling and doesn't seem to engage. I suspect the valves. It has 170478 kilometers on it. Any diagnostic advice or known issues? I know about pressure switches, temperature control, cooling systems, and AC relays.

I had a similar problem with my V50, but it was a petrol engine. First thing to check is the AC relay and the pressure switch. Sometimes they fail without warning. Have you checked those?

Where is the AC relay located in the V50's electrical system? Also, were there any specific error codes with the pressure switch failure in your experience?

The AC relay is usually in the main fuse box, check your manual. I didn't read the error codes for the pressure switch, I just took it to the workshop.

The issue was individual valves, needing part replacements, costing about 1000€.
