Wow your a start mate here are my iid readings, I did do several on off checks and all readings were roughly the same I either got 0 or 1% actuator when ac was on, if I left ac in the evaporator got warmer if I left econ on it got cooler, as to the pull it all seems to be intact and spins with no noise

Eco off (ac on)



with eco turned on

Ur welcome

Just done a conversion with kpa to psi 625 Kilopascal (kPa)= 90.64859 Psi (Psi), so indeed can see ur compressors not running fully

With my data it shows 225. Psi which is 1550 Kpa

See with the eco off and ac on ur compressor shows amperage , would that mean it’s working ??

Could the fault be ur ac control panel, seeing its what turns the ac on and off, apologises I haven’t got the experience how these are tested

Maybe the more knowledgeable members will be able to tell

Would be a right result if it’s the panel and not ur compressor, seeing it spins with no noise

Sorry that’s not much help but thinking maybe testing with a multimeter on the back of ur control panel with what the voltage is in and then back out as u adjust the dials ??

Clutching at straws but see that fault sheet shows what connectors are what , inc what voltages should be there

Have u tried reading error codes with the aircon running to see if any come up plse
