Hi there,
I've got a 54 Plate 130hp 1.9PD Alhambra.
Aircon is not working, in that the compressor doesn't kick in, nor do the fans come on when the AC button is pressed.
If I apply 12v to the green wire at the compressor, the compressor clutch engages... So it's not stuck.
Just tested voltages at the J293 (Relay 454) Fan control Module and got this:
Pin 1 (Black/Red - Ambient Temp Sensor) - AC ON=12v, AC OFF=0v,
Pin 2 (Brown) - Earth,
Pin 3 (Yellow/Red - G65 Pressure Sensor) - 0.67-0.68V,
Pin 4 (White, not sure what it does)- 0.77v,
Pin 5 - EMPTY,
Pin 6 (Red/Wht - Not sure on function) - 13V,
Pin 7 (Brown/Blue - Not sure on function) - AC ON=1.21v, AC OFF=0.02V,
Pin 8 (Green - goes to A/C Compressor) - Earth,
Pin 9 (white - not sure on function)- 0.77V

System is fully charged with no leaks.
