What are the reasons for the radiator fan not working in the Verna?

The reasons for the radiator fan not working in the Verna are: 1. Aging of the fan itself; 2. Sensor signal interference; 3. Relay malfunction. Since the Verna's fan is responsible for dissipating heat from the coolant, a faulty fan can lead to the radiator boiling over, causing the coolant to evaporate and overflow due to high temperatures. In severe cases, this can result in engine seizure or even the risk of total engine failure, so timely inspection and repair are recommended. The Verna is a compact car under Beijing Hyundai, with body dimensions of 4300mm in length, 1705mm in width, and 1460mm in height, a wheelbase of 2570mm, a fuel tank capacity of 43L, a trunk capacity of 475L, and a body structure of a 4-door, 5-seater sedan.
I drove a similar car when I was younger and experienced the radiator fan not working several times. The most common issue is a blown fuse—it's in that small box in the engine bay; you can open it yourself and check. If it's blackened or broken, replace it immediately. The relay could also fail, especially in older cars where wiring corrosion can cause poor contact and prevent the fan from running. Another possibility is a faulty thermostat switch—the fan only starts when it receives a temperature signal, so if the sensor is broken, the fan won't move at all. The worst-case scenario is a broken fan motor, which may produce strange noises or fail to spin, requiring disassembly for inspection. If not addressed promptly, the engine can overheat, smoke, and stall, which is very dangerous. It's best to find a reliable repair shop to handle it—spending some money ensures peace of mind.
As someone who has been repairing cars for many years, I've seen all kinds of cases where the fan doesn't work. Most of the time, it's because the fan motor is stuck or burnt out, and worn bearings will make a squeaking sound. Blown fuses are also quite common, especially in summer when the air conditioning is used more frequently, causing higher current that can easily blow fuses. Burnt relay contacts are also a frequent issue—you can test by short-circuiting the relay terminals to see if the fan spins. Short circuits in the wiring or a faulty thermostat can also cause the fan to stop; use a multimeter to check the voltage for troubleshooting. I don't recommend non-professional car owners tinkering with the electrical circuits, as it can easily lead to bigger problems. When sending the car for repair, emphasize checking the control system for a more reliable fix. Remember to regularly maintain and clean the cooling system to prevent issues.
