Why is my Vauxhall Zafira Life making a strange noise when I turn on the A/C?

I recently noticed that when I turn on the air conditioning in my Vauxhall Zafira Life, there is a loud rattling noise coming from the engine. It only happens when I first turn on the A/C and then goes away, but it's concerning me. Any ideas on what could be causing this?

It sounds like there may be an issue with your A/C compressor. I would advise taking your car to a licensed mechanic to have it checked out.

I had a similar issue with my Zafira Life and it turned out to be a loose belt on the A/C compressor. I tightened it up and the noise went away.

This could also be caused by a dirty or clogged air filter. I would recommend checking and changing the filter if necessary.
