Why is my Kia Rio making a weird noise when I turn on the AC?

Every time I turn on the AC in my Kia Rio, there is a loud whirring noise coming from the engine. Is this a common issue with the Kia Rio? What could be causing this and how can I fix it?

This could be caused by a faulty AC compressor or a worn-out belt. I suggest taking your Kia Rio to a mechanic to get it checked and repaired.

I had a similar issue with my Kia Rio and it turned out to be a loose AC belt. My mechanic tightened it and the noise went away. Get it checked to be sure.

Make sure to check your AC system's refrigerant levels as well. Low levels can also cause strange noises. If that's the case, have the refrigerant refilled by a professional.
