    Hello
    The problem is that the air conditioning compressor does not start.
    What I checked and did:
    At the end of last year, the controller from the radiator fan burned "alive".
    I replaced the driver with a new one and thought it was ok, it was cool so the engine did not overheat.
    Now how it got warm and you need to start the air conditioning, it turned out that it does not work, a fan error by computer.
    I looked and found 2 reasons, burnt 60A fuse from the fan and the famous purple cable in the fan plug was not at all.
    Both faults repaired and the compressor still does not start.
    The remaining fuses are in working order, the fan starts up from time to time, the compressor, after being shorted on the relay, works, the cooling starts to cool down, the pressure does not increase too much.
    I am filling myself with air conditioning in cars, I will add.
    No errors by computer.
    I wonder just how much refrigerant should I fill the system with a sticker like that in front of me.
    Dual zone air conditioning.
    Everyone told me to fill 560g and it will work but they were suggested by catalogs.
    I will add that I am the first owner of this car in Poland and the first user of air conditioning in this car, because the previous 1 owner could not use air conditioning. (The system was empty when the car hit me, I checked the tightness and filled the catalog according to the suggestions of several workshops)

    You checked the pressure switch?
    Releasing the compressor without a review after such inactivity can be risky. I would recommend a review on the site, and for that he definitely set up a new dehumidifier and of course replace the whole oil with a new one.

    Do you think that? As I mentioned, this air conditioning was never used.
    How to measure this pressure switch? There are 3 pins.
    And it is on the low pressure side. On the high side I did not find pressure protection.

    I gave the car to the electrician and it turned out that the fan controller, despite the fact that the new one and the number agreed, was a substitute and they did not agree on resistance.
    Replacing the used original has settled the matter.
