Hello, I have a Peugeot 307. I have a problem with the fan in the car. For example, when I start the fan, there is no problem. Everything is normal. I drive for a few km. There is no problem. I mean, the fan turns on and off. Everything is normal. But after a while, the fan turns on but does not turn off. When I leave the car off for a few minutes, it returns to normal. But as long as I continue like this, it does not turn off and there is no overheating but it does not cool down much. The problem occurs when the fan comes on. When these do not come off, everything is normal. I wonder what could be the cause?
