Sounds like you are doing everything I would try. So, the clutch pulls in and the compressor compresses with the 12v to the clutch if I'm reading right. Does it make pressure on your gauges? Then does it drop the clutch when the pressure comes up denoting the pressure switch is doing its thing?
You need a wiring diagram so you can follow and see about what makes that ccc thing go. One bad resistor or even a cracked solder joint can put it into intermittent or worse.
Good luck. You might try the gnttype place for wiring diagrams or maybe steves site.
I knida gave up on the big board as they put in a bunch of popup things and I just don't want to deal with all that.
