How to fix the air conditioning in my Vauxhall Vivaro?

The air conditioning in my Vauxhall Vivaro has stopped working and I'm not sure how to fix it. Any advice?

First, check to see if the AC compressor is turning on when you turn on the AC. If not, it could be a faulty compressor. If it is turning on, then you may need to recharge the AC refrigerant.

One common issue with Vauxhall Vivaros is a faulty AC relay. Check and test the relay to see if it needs to be replaced.

If the AC is blowing warm air, it could be a sign of low refrigerant. Have a mechanic check for any leaks and recharge the system if needed.
