Why is my Vauxhall Astra making a strange noise when I turn on the air conditioning?

I recently noticed that my Vauxhall Astra is making a strange noise whenever I turn on the air conditioning. It sounds like a buzzing or rattling noise and it only happens when the AC is turned on. What could be causing this and how can I fix it?

Hi Samantha, this could be caused by a few different things. It's possible that there is a problem with the AC compressor or a loose belt. It could also be due to a clog in the AC system or low refrigerant levels. I recommend taking your car to a mechanic to diagnose and fix the issue.

Hey Samantha, I had a similar issue with my Astra before. It turned out to be a problem with the AC fan motor. It needed to be replaced and now my AC works perfectly. I suggest getting your fan motor checked out by a mechanic.

Hi Samantha, I had a similar problem with my Astra a while ago. It was due to a faulty AC relay. I had it replaced and the noise went away. I recommend having your mechanic check the AC relay to see if that's the issue.
