What should I do if my Vauxhall Astra's AC is not working?

I recently noticed that my Vauxhall Astra's AC is not functioning properly. No matter how low I set the temperature, it still blows hot air. What could be the cause of this issue and what steps should I take to fix it?

First, check if your AC compressor is running. If not, it could be a sign of a faulty compressor or a problem with the AC clutch.

It's also worth checking the fuses related to the AC system. If they are fine, the issue could be with the AC control module or the AC pressure switch.

Another possibility is a refrigerant leak. If this is the case, you'll need to take your car to a professional for repair and recharge.
