it may be because the aircon swithch is on.
or someone shorted it to work as a prevention to engine overheating.
Yes, if the radiator fan is not working, it can cause overheating of the engine. The radiator fan helps to cool down the engine by pulling air through the radiator to remove heat. Without the fan, the engine may not receive adequate cooling, leading to overheating.
Engine overheating or cooling fan running all the time.
cooling fan opperation. and thermostat
If the question is about the motor fan or engine fan, the main function of this fan is cooling the radiator of the engine which in turn is cooling the water circulating inside the engine unto the radiator and back. This keeps the engine at a fairly operable temperature without overheating and damaging damaging its parts.

If the cooling fan is turning slow on a vehicle then the motor is dying. The fans should be replaced in order to avoid an overheating issues that can arise in the engine.
A relay for a radiator cooling fan motor is an electrical component that acts as a switch, controlling the operation of the cooling fan in a vehicle's radiator system. When the engine reaches a certain temperature, the thermostat sends a signal to the relay, which then activates the fan motor to help dissipate heat and maintain optimal engine temperature. This ensures efficient cooling and prevents overheating. If the relay fails, the cooling fan may not operate, leading to potential engine damage.
check fuse for cooling fan, or possibly temperature sensor at inlet.
It could possibly be the thermostat or the cooling fan. Let the engine warm up and when it gets to 232 to 235 degrees the cooling fan should come on. If not you need to go from there.
Check coolant level Check the operation of the cooling fan
If the temperature gauge does not activate, it typically indicates that the engine is not overheating or that there may be an issue with the gauge itself. However, many vehicles have separate sensors that control the cooling fan, so the fan may still activate if the engine reaches a certain temperature, even if the gauge does not reflect it. If the fan does not come on when needed, it could signal a malfunction in the cooling system, potentially leading to overheating. It's advisable to check the vehicle's cooling system and sensors for any issues.
The engine cooling relay is typically connected to the vehicle's cooling fan, temperature sensors, and the engine control unit (ECU). When the engine temperature exceeds a certain threshold, the temperature sensor signals the ECU, which activates the relay to power the cooling fan. This helps maintain optimal engine temperature and prevents overheating. Additionally, the relay may be connected to the vehicle's electrical system, allowing it to function properly.
