Air Con Stopped working.

[Legionaro]

Hey guys got a 1997 c34 series one Stagea,

 

A/C randomly stopped working, the a/c pump wont engage, tested the clutch its all good.

Thought it was the pressure sensor due to the fact that if you earth it out it the a/c clutch engages but no go there fitted a new one genuine one and still nothing.

Was wondering does anyone have a wire diagram for C34 series one auto climate control to see if the ecu or the control unit it sending out earth.

 

Thanks

Did you not stop to think that if you earth the switch and the AC switches on, and you replace the switch but it still won't switch on, that perhaps the switch is doing what it is supposed to do and preventing the compressor from starting when the gas pressure is too low because half of it has fallen out?

Probably should have mentioned that it was degassed/regassed to spec when the new pressure sensor was fitted.
