Why is my Vauxhall Zafira Life's air conditioning system not cooling?

I've noticed that my Vauxhall Zafira Life's air conditioning system is not cooling as well as it used to. What could be causing this issue and how can I resolve it?

The most common reason for a decrease in cooling efficiency is a leak in the refrigerant system. You should have your system checked for leaks and have any necessary repairs done. Also, make sure to regularly clean or replace the air filter to prevent blockages.

Another factor that can affect the cooling of your AC is the compressor. If it is not functioning properly, it can result in uneven cooling or no cooling at all. Have a professional check the compressor and replace it if necessary.

Low refrigerant levels can also cause cooling issues. It is important to have the system recharged regularly to maintain proper refrigerant levels.

Sometimes, the problem can be as simple as a faulty thermostat. Have it checked and replaced if needed.
