Berlingo B9 AC problem

[igli]

Hello, I have a Berlingo 2010 with 1.6 Hdi diesel engine. It's a multispace and got 320k km, still going strong... 
But this season I've notice that my AC is not blowing cold air anymore. When I press the ac button, clutch on the ac compressor is engaging, but just for few seconds, then is off. 
I try to replace this pressure switch in the ac line, but still the same. 

Is anyone had a similar problem? 

Regards

Far as I understand it if the pressure switch measures nil pressure it would probably do what you describe. Have pressure checked and Regas if necessary would be my next move I think.

It doesent want to pull the gas, we try to regas it. Are there 2 pressure switches or only one at the top left ?
Does anyone have wiring diagram for ac for Berlingo 2010, 1.6 Hdi ?

Thanks in advance

Hi Igli

This is a diagram for AC with not automatic control.

Thanks for that, here is the status now: 

We change the AC condensor, it was cracked, after that we could fill in the gas and AC starts to work and blow cold air in the cabin... But this is not the end of the story for me, in idle AC works super cold, but when I start to drive the car and go after 1800 rpm, AC cuts out and wont engage anymore, until I shut the car down and turn it back on. 

Next step: we change the pressure switch, with the OEM one, because diagnostic was showing something about short to ground on this pressure switch. 
This also didn't resolve the problem. 

Do you think, maybe something is wrong with wiring from pressure switch to whatever it goes ?
