I have tried everything else, and now I am looking for my last hope before my precious v50 is being sold in parts.

The car can´t keep the temperature down, and the AC sounds strange from the passenger side. I will give as a good description as possible.

Since the car was transformed from a driving school car to normal, the temperature has risen up over normal at many occasions. And I and many others have tried almost everything to fix the problem. The first symptom we believed was a bad gasket, but this have been tested at several mechanics with a pressure test to exclude it. The car isn't leaking cooling liquid so the problem is somewhere else.

Second hypothesis was that the termostat or water pump was bad, so this was changed, but car is still going high.

Third hypothesis was that the temperature sensor was bad so this was changed without any difference.

Fourth hypothesis was that the radiator and fan was bad, so this was also changed without any difference, but here I found something odd. I have electric to the fan, so relay isn't bad, but it seems like it is acting strange, and not working properly. It is not turning on, and when I am giving pressure by my hand, then it seems to get resistance and starts. So I believe here is one hypothesis that can be the problem, but I have tried to replace the whole thing, with the module to the fan, but it was the same. I will attach videos and I hope one guy here can understand where my problem is so I can keep my favorite car.
