How do I troubleshoot a malfunctioning AC system in my Vauxhall Zafira Life?

I noticed that my AC is blowing hot air instead of cold, and the compressor seems to be running constantly. What could be the cause of this and how can I fix it? I don't have prior experience with car repairs, so any advice would be greatly appreciated.

First, check the refrigerant levels in your AC system. Low levels can cause the compressor to work harder and overheat. If the levels are low, you can either refill the refrigerant yourself or take it to a mechanic for a professional refill.

Another potential issue could be a faulty AC compressor clutch. This can be diagnosed by testing the electrical connections to the AC compressor using a multimeter. If the connections are good, then the clutch may need to be replaced.

It's also important to regularly clean or replace the cabin air filter in your Zafira Life. A clogged filter can restrict air flow and cause the AC to blow hot air. This is a relatively simple task that can be done at home.
