I evacuated and recharged my ac on my 1990 740. It worked well, but receiver/drier would still begin to freeze after 20 mins of driving. I suspected the lo prssr switch. I removed it and noticed that it had an adjustment screw. I saw that ari posted on another board that he has used this screw. I think that I need my compressor to cycle at a higher low pressure, so I turned the screw clockwise a half of turn. Now I'll have to take it out for a drive and test it. Any thoughts?
