X300 Air con issue but no faults.

[felga]

I recently had my xj6 3.2 serviced and after the winter AC stopped working. I had mobile AC guy around to regass it and check for leaks.

I run the HVAC diagnostic procedure on the dash and it`s showing 0 , so no faults.
But the ac clutch still doesn`t start. SO chased a cable to see if the clutch works at all and plugged 12+ directly from battery and it does.

Fuses f8 and f10 have 12v on both sides, swapped ac clutch relay and still nothing.

The voltage with AC off on the clutch is 0v with AC on is 0.5v.

Anyone have any suggestions what next :/ ???

Could be the pressure switch or connections, it's the one with four wires, if pressure is sufficient it should earth the Blue/Black Stripe wire.
