In addition to the coolant temperature sensor in the Skoda Fabia II AC fan circuit, there is another element-a fan control unit that causes problems more often than other components. Generally, it is possible to judge the breakdown by specific behavior: the fan continues to operate even after the ignition is turned off and the battery is closed. In this case, you need to run diagnostics on the auto-electro, because these symptoms are similar to the system's behavior in the event of a temperature sensor failure, and only the specialist can understand the problem with the tester.
