A/C Air conditioning Opel Insignia don't work

[snorg]

Hello,

I have a problem with the insignia, the air conditioning does not turn on


Well, with the air conditioning off, it is 490 kpa, when you turn on the compressor with a snowflake, after about 20 seconds, it rises to 3000 kpa, the fan at 100% revs to the max and immediately turns off and the pressure in the system drops again to about 600-700 kpa, what does that mean?
what's happening ? no errors
