What are the reasons why the fan cannot rotate normally when idling?
1 Answers
The reasons why the fan cannot rotate normally when idling include: the car's water temperature not meeting the requirements, relay failure, or issues with the temperature control switch. Below are the specific details: Car's water temperature not meeting the requirements: Most car radiator fans operate based on electronic temperature control. The fan will only rotate normally when the car's internal water temperature reaches the required level. If the temperature is too low, the radiator fan will not rotate. If the car radiator fan fails to rotate, the first step is to check whether the water temperature meets the requirements. If the water temperature cannot rise, the car engine needs to be inspected. Relay failure: If the water temperature meets the requirements but the car radiator fan still does not work, the issue might be with the fan's relay. In this case, the damaged relay needs to be replaced. Issues with the temperature control switch: A faulty temperature control switch can also affect the operation of the car radiator fan. Therefore, it is important to inspect and replace any damaged temperature control switches.
