Engine fan not turning off
I came back from a movie at the theatres and my car wouldn't start......the battery was dead. As I jump-started the car, I noticed/heard what sounded like a fan near the engine. This fan was on the whole time even though the car was turned off and the key wasn't even in the ignition.
Does anyone know what is wrong? I own a 2000 BMW 328Ci.
Much appreciated, thanks!
