How to fix a non-functioning air conditioning in an Audi A2?

My Audi A2's air conditioning is not working. It's blowing warm air instead of cold. What steps can I take to fix this issue?

First, you should check the air conditioning compressor to make sure it is functioning properly. If not, it may need to be replaced.

You may also want to check the refrigerant levels in your car. Low levels can cause the air conditioning to blow warm air.

Another possible issue could be a clogged air filter. Make sure to replace it regularly to ensure your air conditioning is working efficiently.
