How to fix a faulty AC in a Vauxhall Zafira Life?

My Vauxhall Zafira Life's AC is not functioning properly. Whenever I turn it on, it only blows out warm air. How can I fix this issue?

First, check the AC compressor and see if it needs to be replaced. If so, take it to a trusted mechanic.

Another potential cause is a low refrigerant level. You can easily add more refrigerant yourself using a kit.

If none of these solutions work, then there might be an issue with the AC system's electrical components. It's best to have a professional diagnose and fix the issue.
