Humming noises from the AC and fan in an Audi A1

Hi, I have a 2012 Audi A1 with a gasoline engine and 20,000 km on the odometer. I've noticed that the fan isn't working properly. When I turn on the AC and the fan, I hear a humming sound, but the sound stops when I turn the fan off. What could be causing this problem and how can I fix it?

Check if there is any debris or obstruction in the fan blades that might be causing the humming sound. If the fan is clear, the issue might be with the fan motor or a loose belt. Inspect these components for any visible damage or wear. If you're unsure, it's best to have a mechanic take a look to ensure it's safe to drive. Let me know how it goes or if you have any other questions!
