What causes the Wuling Hongguang S fan to not rotate?
2 Answers
Reasons why the car fan does not rotate are as follows: Coolant temperature not reaching the required level: Most modern car radiator fans operate using electronic temperature control. Therefore, the fan will only start rotating normally when the engine coolant reaches the specified temperature. If the temperature is too low, the radiator fan will not rotate. Hence, if the car radiator fan is not working, the first thing to check is whether the coolant temperature has reached the required level. Relay malfunction: If the coolant temperature is appropriate but the car radiator fan still does not work, the issue might lie with the fan relay. A faulty relay can prevent the radiator fan from operating. Thermostat switch problem: If neither of the above issues is present, then the thermostat switch should be inspected. This component can sometimes develop faults, which may affect the operation of the car radiator fan. Therefore, it is important to check this as well.
With over a decade of experience in car repair, I've encountered numerous cases where the Wuling Hongguang S fan fails to operate. The most common issues are blown fuses or faulty relays. This vehicle's fan is primarily electrically driven, so if the fuse in the engine compartment's fuse box blows, the fan won't function. Similarly, if the relay's contacts age or the coil shorts, it will cut off the power supply. Problems with the fan motor itself, such as worn carbon brushes or seized bearings, are also frequent, especially during hot seasons, leading to poor cooling. Faulty temperature sensors or poor wiring connections are not uncommon either. For a quick self-check, start by inspecting the fan-related fuse in the fuse box—if it's blown, replace it with an identical one. If that doesn't work, listen for a clicking sound from the relay when power is applied; if there's no response, it likely needs replacement. It's best to have a professional shop test with a multimeter, as neglecting repairs could cause engine overheating and damage. Regular maintenance, like cleaning the fan plug and housing to remove dust buildup, can help prevent failures.
