Wuling Hongguang electric fan has only one rotation. The function of the car electric fan is to cool down the engine radiator. When the engine temperature rises to the set limit, the electric fan starts working. Once the water temperature drops to the lower limit, the thermostat cuts off the power, and the fan stops working. Below are the reasons why the electric fan may not rotate: 1. Poor motor lubrication: The fan does not rotate due to insufficient lubrication of the motor, making it unable to drive the fan blades after installation; 2. Motor overheating: Overheating of the motor can also reduce its load capacity and effective power, leading to an inability to drive the load; 3. Reduced starting capacitor capacity: The capacitor capacity may decrease, reducing the motor's starting torque and making it unable to drive the load; 4. Prolonged motor usage: If the fan has been used for too long, the motor may wear out. After the motor's shaft sleeve wears, it can easily burn out. Prolonged use of the motor can also increase its internal resistance, reducing its load capacity and making it unable to rotate the fan blades.

I've driven the Wuling Hongguang for five years and am quite familiar with it. There are usually two electric fans—a large main fan responsible for primary cooling and a smaller auxiliary fan that activates under specific conditions. It's normal to see only the main fan running under regular circumstances. Both fans will operate when using air conditioning in summer or when climbing hills. If you notice only one fan running, don't panic—check for loose fan connectors, blown fuses, or a faulty coolant temperature sensor. If neither fan works, the control module might be malfunctioning, and you should promptly visit a repair shop. The fans are crucial for cooling, especially during idling in traffic jams.

I often use the Hongguang for deliveries and have specifically observed the fan operation. Most older Hongguang models feature a dual-fan design, though base versions may only have a single fan. Whether the fans operate depends on temperature—one fan is usually sufficient during normal driving, and the second fan kicks in only when the radiator temperature rises significantly. If you notice reduced air conditioning cooling efficiency or rising engine coolant temperature, it's advisable to check whether the fans are stuck or if there's poor electrical contact. You can try unplugging the fan connector to clean the copper contacts or tightening the mounting screws yourself, as these simple fixes often resolve contact issues. However, for replacing the motor, it's safer to consult a professional mechanic.

Having observed many Wuling Hongguang engine compartments, the electric fans usually work in parallel. The small fan is located on the left side of the front end, while the main fan is positioned more centrally, secured by a plastic bracket. The simplest way to check them is to turn the key to the power-on position and turn on the air conditioning to see if both fans spin simultaneously. If only one is spinning, it's likely an electrical issue, such as a faulty temperature control switch or relay failure. For DIY repairs, you can try swapping the relay—replacing the switch for just a few dozen yuan can solve the problem, saving you hundreds compared to a repair shop visit. Remember to regularly clean the fan blades of mud and dust.

The cooling system design of the Hongguang is quite practical, with most configurations featuring dual fans. When there is a high demand for cooling, the air conditioning compressor will command the fans to operate at full capacity. It's worth noting a particular phenomenon: although both fans are present, they will run simultaneously when the air conditioning is on, but only the main fan operates when the coolant temperature is high. If you notice this and suspect an issue, don't panic immediately. Instead, take some time to let the engine idle for twenty minutes; the fans should activate as needed. If the system consistently operates with only one fan, check for oxidized wiring connections or insufficient power supply voltage. When replacing fan blades, it's advisable to opt for original equipment manufacturer (OEM) parts, as aftermarket ones often have poor balance, leading to vibrations and unusual noises.
