Just my 2 cents but are you sure the fitting the pressure switch sits in is clear and not plugged up?? Atmospheric pressure will allow the compressor to run full time.

I put gages on it and found that my low side pressure was dipping into the low teens, while my high side was blowing up way over 300 when the car was revved. The low pressure switch never kicked off the compressor, so I pulled the plug off the low pressure switch and everything stops as it should. So I replaced the low pressure switch. No change, everything on. Then I tried adjusting the switch to the extremes (both directions) with no change. I even switched it out with a known good switch with no change.
