What causes the air conditioning to stop working in a Vauxhall Astra?

I have a 2010 Vauxhall Astra and recently the air conditioning has stopped working. The air blows out but it's not cold. What could be causing this and how can I fix it?

The most common cause for the air conditioning to stop working is a low refrigerant level. This can happen over time due to normal wear and tear or if there is a leak in the system. It's best to take your car to a mechanic to have the refrigerant levels checked and topped up if necessary.

Another possible cause for the air conditioning to stop working is a faulty compressor. This is the part of the system that pressurizes the refrigerant and allows it to cool the air. If the compressor is not working properly, it can result in warm air blowing out. It's best to have a mechanic inspect and replace the compressor if necessary.

Sometimes, debris can accumulate in the air conditioning system, causing it to work inefficiently or not at all. It's a good idea to have the system flushed and cleaned regularly to prevent this from happening. A mechanic can perform this service for you.
