How to fix the AC in my Vauxhall Vivaro?

My AC has stopped working in my Vauxhall Vivaro. It used to work fine, but now it doesn't cool the air at all. What could be the issue and how can I fix it?

The first thing to check is the AC compressor. If it is faulty, it will need to be replaced.

Another possible issue could be a leak in the AC system. Have a mechanic perform a pressure test to identify any leaks.

Check the AC refrigerant levels. If they are low, try adding more to see if that solves the issue.
