Hello, I have a Peugeot 307. I have a problem with the fan in the car. For example, I start the fan and there is no problem. I drive for a few kilometers and there is no problem. I mean, the fan turns on and off and everything is normal. But after a while, the fan turns on and 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 and it does not cool down much. Of course, these are the problems that occur when the car starts working. Otherwise, everything works normally. What could be the cause?
