    volvo a/c are very simple and friendly to diagnose on version1 . fist, disconnect de apads module and put power 12 volt on pin h(green wire). your a/c should run, doing this , you by-pass all the input coming from the cab, if a/c run with 12 volt on pin h, it's a cold switch problem or diode behind heater control. if a/c do not run, mostly an open circuit in the wiring of a/c compressor or switch

    How much pressure should the refrigerant have on the gauges when you are checking it?
