With a test light,test for power at pressure switch on accumulator.It is near the re-charge port.Do this with engine running and controls set to cool.If voltage is present at either side of switch,control unit is probably OK.The later control unit will work,but that type does not often fail.The pressure switch often fails and can be changed without losing system charge.
