Hello together, I bought today a Ford Ka Bj 97. This is my first Ford ever. The vehicle has run 70 tkm and is in a very good condition. Unfortunately, the air conditioning does not bring the desired performance which behaves as follows: Turn on the air conditioning (of course with running engine), light control light, you can hear a switching noise in the vehicle room (relay ? ), however, the typical one-coupling noise of the air conditioning compressor and a corresponding rotation fence are missing The engine, which I know from many other vehicles. There is no particularly cold air. Outside temperature >5° Who can give me a tip or give me possible causes of error ? I don’t necessarily want to go to a workshop. Thank you
