Ford Fiesta radiator fan not working, blowing hot air issue unresolved on Ford Fiesta

Some Ford Fiesta owners report experiencing issues with the radiator fan not functioning, which can lead to the vehicle blowing hot air. Common problems include a blown fuse, which may only provide a temporary fix if underlying wiring issues are not addressed. Additionally, issues with the fan assembly, fan clutch, or coolant temperature sensor are frequently cited as reasons for fan failure. Owners may need to test various components such as the cooling fan assembly, thermostat, and cooling fan resistor to troubleshoot effectively. Observing the fan's behavior, such as whether it only activates when the engine is very hot or continues running after shutdown, can also indicate potential thermostat problems. Some owners have found that disconnecting the sensor wire can help determine if the sensor is faulty, as the fan may start working in response. Systematic testing of these components is essential for identifying and resolving the root cause of the radiator fan issue, ensuring the cooling system operates properly.
