Technical Ducato x290 airconditioning schematics

[perzonator]

Hello everybody,

I'm new to this forum and love to see all the information that is at hand.
I'm currently working on a X290 3.0JTD Ducato with a friend and the airconditioning isn't working.
We can hot wire it on the relais and everything works fine.
It has a new condensor and new pressure sensor and everything is filled of and no errors on the aircon tester.
OBD gives a relais circuit error.
Is there someone with a schematic for this all so that we can further troubleshoot the problem?

Kind regards

Perry

Hi Perry

I attach a document I wrote, which is based on the elearn information for the X250 vans (2006 to 2014). Your later van may be very similar, so I hope it gives you some ideas. Information on the later vans is difficult to source.

The air conditioning will not work if the cabin fan is on Zero, it must be on 1 or more. If the cabin fan is faulty, this might prevent the air conditioning from working.
