Why does my engine cooling fan keep running?
It’s normal for some vehicles to have a fan run for a few minutes after the car is shut off, generally to keep the engine cool. However, if the fan is running for an extended period, the fan itself can become damaged due to overuse. It’s possible you may have a module or relay failing in your car.Muh. 27, 1437 AH
