How to troubleshoot air conditioning issues in my Vauxhall Zafira Life?

My Vauxhall Zafira Life's air conditioning has stopped working. The cool air will only come on for a short period of time before turning warm. How can I troubleshoot and fix this issue on my own?

First, check if your air filter needs to be changed. A dirty filter can restrict air flow and cause the air conditioning to malfunction. If that doesn't solve the issue, it could be a problem with the compressor.

Another possible issue could be a low refrigerant level. In this case, you will need to take your car to a professional to have it recharged. Also, make sure there are no leaks in the system.

If the air conditioning still doesn't work after checking the filter and refrigerant, it could be an electrical problem. Check the fuses and wiring, or take it to a mechanic for further diagnosis.
