Hello,
I have a similar problem, when I give contact to the car, the fans turn on and work all the time until I turn off the car. The thermostat, temperature sensor and fan module have been changed. It's none of those things! They stop working as soon as the engine is on optimal temperature, but as soon as the car cools down and turn on again, they start working….
If anyone has any advice? Tnx
