What is the Reason for the Fan Noise After Parking a Tesla?
1 Answers
Tesla may produce fan noise after parking because the fan inside the car serves a cooling function. After parking, if the coolant temperature is too high, the computer will automatically calculate the fan speed and duration to protect the engine, which is a normal phenomenon. However, if the fan continues to run for an excessively long time even after the engine temperature has dropped, it may be due to a loose circuit connection. In such cases, you can try disconnecting the fan wiring harness to cut off the power separately. Additionally, the issue might be caused by a faulty water temperature sensor or a stuck fan relay contact, which can be resolved by replacing the component at a repair shop. Modern car radiator fans operate based on electronic temperature control. Therefore, the fan typically starts running only when the internal water temperature reaches the required level. If the temperature is too low, the radiator fan will not operate. Hence, if the car radiator fan malfunctions, it is essential to check whether the water temperature meets the required standard.
