That same thing bothers somewhat. I don't know why modern cars have gotten away from the little thermosadt/switch that controls the compressor. It seems really inefficient that I have to regulate the amount of cold air I dump into the cabin by mixing warm air with it, rather than the compressor cycling off and on.

My Dodge pickup (and some Japanese cars I've seen) has a little push button that engages the compressor. When you start getting too cold, you punch the button again and it disengages the compressor. Getting warm? - punch it again, etc. Even that's not as good as the old style thermostadts, but it's much less cumbersome than the controls in our 740.

I don't know why you couldn't put one in your Volvo. You'd have to make certain it could handle the current demanded by the compressor clutch, or work a relay into the equation.
