Berlingo m59 DW8B A\C doesnt work - BSI?

[ori793]

Hello,

A m59 (model 2005 engine WJY) berlingo arrived in my workshop yesterday with AC doenst work,
checked the car and found out the harness to the compressor clutch was shorting,
both wires were exposed and touching each other.

installed a new clutch and fixed a new harness,
but AC clutch wont get any current (+) with the AC Button ON.

using G-Scan actuators i managed to get the AC on, but normally it would not work.
therefore i am not certain it's a BSI problem, or there is something on the way avoiding the system from working.

of course the system is fully loaded with a134, and there are no fault codes in any system, and the car does not overheat.

Thank you for your help.

Check in live data for correct readings & commands.
Trace circuit back to feed supply fault?

if you can actuate via diag tool, then i would say bsi is ok, check pressure sensor in ac line.

dont forget to press thanks

Hello,

I had the same problem in same car a few years ago, check the welds on the relays of the BSI.

PDF is in French, sorry.
