Why is my Vauxhall Insignia's air conditioning not working?

I recently bought a used Vauxhall Insignia and noticed that the air conditioning is not working properly. The air blows out cool, but not cold. What could be causing this issue and how can I fix it? Thanks!

It's possible that your air conditioning system is low on refrigerant. You can try adding a recharge kit, but if that doesn't work, it's best to have a professional inspect and repair the system.

Another potential issue could be a faulty compressor. This can be a costly repair, so it's important to have it diagnosed by a professional before jumping to conclusions.

If your coolant levels are low, this could also affect your air conditioning system. Check the coolant levels and top them up if necessary.
