Why is my Kia Picanto making a strange noise when I turn on the AC?

My Kia Picanto has recently started making a loud rattling noise whenever I turn on the AC. It sounds like it's coming from the engine compartment. What could be causing this and how can I fix it?

It's likely that the noise is coming from the AC compressor. You should have it checked by a mechanic as it could potentially break and cause further damage to your car.

It could be a loose belt or a malfunctioning fan. I would suggest taking it to a mechanic for a proper diagnosis and repair.

Try cleaning or replacing your AC filter. If it's clogged, it can cause strange noises and reduce the effectiveness of your AC.
