How do I fix the air conditioning in my Vauxhall Astra?

My Vauxhall Astra's air conditioning stopped working and I'm not sure what the issue is. The system won't blow cold air and I can't figure out how to fix it. Anyone have any ideas?

Have you checked the refrigerant levels in your Astra's air conditioning system? Low refrigerant can cause the air to blow warm.

Check your Astra's compressor. If it's not functioning properly, it can also cause the air conditioning to stop working.

Another common issue with Astra's air conditioning is a faulty condenser. Make sure to check that as well.
