What is the reason for the normal power supply but the fan not working in Fukang cars?

The reason for the normal power supply but the fan not working in Fukang cars is a relay failure. Relay: A relay is an automatic control device where the output undergoes a sudden change when the input reaches a certain value. Relays can switch high load power and have high impact and vibration resistance. The power supply in cars is mostly 12V, and the coil voltage is mostly designed to be 12V. Function of the fan: The function of the fan is to increase the air flow rate through the radiator core, enhance the heat dissipation effect, and accelerate the cooling of water. The fans used in car engines are divided into axial flow fans and centrifugal fans according to their structural principles; according to their driving method, they are divided into mechanically driven and electrically driven. Modern car engines widely use electrically driven centrifugal fans.
I found that my Fukang car has normal power but the fan isn't spinning, and there could be many reasons. A blown fuse is the most common issue—open the fuse box under the hood and check if the fan-related fuse is intact. Relay failure is also frequent; that little black box controls the current and can fail due to aging or short circuits. The fan motor might be broken or jammed, with blades stuck by dust or debris, so cleaning it thoroughly is necessary. A faulty temperature sensor can also cause this, as the computer won't receive the high-temperature signal and thus won't activate the fan. Loose or oxidized wiring connections can lead to poor contact and interrupt the current. I recommend checking the fuse first—it's quick and easy. If that's fine, try powering the fan directly to see if it spins. A non-spinning fan can easily cause engine overheating, posing a big risk in summer, so address it promptly to avoid a breakdown. Regularly cleaning the fan blades to prevent blockages can help reduce such issues.
I've driven several Fukang cars in my lifetime and encountered the fan not spinning issue several times. Generally, if the power is on normally but the fan doesn't move, there's a 90% chance it's a blown fuse, especially during rainy seasons or on poor road conditions when it's prone to burn out. Relay failures are also very common—they're cheap but prone to wear from frequent switching. It's not unusual for the fan to get stuck due to small stones or leaves; sometimes just cleaning it out solves the problem. Once, my car's fan stopped working because the wiring connector came loose, and simply reinserting it tightly fixed the issue. When driving with the fan not spinning, the engine temperature rises rapidly, which is particularly dangerous in traffic jams as it can overheat and stall at any moment. My advice is not to push your luck—stop immediately to check the fuse and relay. If those are fine, head to a professional shop to inspect the sensor or fan motor. Safety first—don't delay. Make it a habit to regularly start the car and observe whether the fan spins afterward; it saves a lot of hassle.
