How to fix a faulty air conditioning system in a Vauxhall Zafira Life?

My Vauxhall Zafira Life's air conditioning system is not working properly. It doesn't blow cool air and sometimes it doesn't turn on at all. What could be the cause and how can I fix it?

Firstly, check the refrigerant levels in your air conditioning system. Low levels of refrigerant can cause the system to malfunction.

Another common issue with faulty air conditioning systems in cars is a faulty compressor. Have a mechanic check and replace the compressor if necessary.

If the air conditioning system is blowing cool air but it's not cooling the cabin, check the cabin air filter. It may be clogged and in need of replacement.
