What are the reasons why the engine fan does not rotate

The reason is that the water temperature is not well controlled, there is a problem with the relay of the Computer fan, there is a problem with the temperature control switch, and the fuse is burned out. Turn on the ignition switch and turn on the AC switch without starting the engine. If the electronic fan rotates, the temperature control switch is damaged. If the electronic fan does not work, it is likely that the electronic fan is damaged.

If the water temperature control is not good, the engine fan will not turn. Currently, many engine fans are controlled by electronic temperature control systems and are very sensitive to water temperature. If the water temperature of the car does not meet the standards of the electronic temperature control system, it will not send a signal to the engine fan switch. At this point, the engine fan will not rotate, which usually occurs during a cold start.

There is a problem with the radiator fan relay. When the water temperature reaches a certain level and the engine fan still does not turn, there may be a problem with the automotive engine fan relay. The car engine fan relay is malfunctioning and unable to transmit signals. At this point, the engine cooling fan cannot operate. There is a problem with the temperature control switch. After inspection, it was found that there were no issues with the car engine water temperature and cooling fan relay. Another possibility is that the temperature control switch is faulty, and it is necessary to check the switch of the car's temperature control system.
