How to troubleshoot a non-functioning air conditioning in an Audi 80?

I turned on my air conditioning but it is not blowing cold air. What steps can I take to identify and resolve the issue?

Check the refrigerant level as low levels can cause the air conditioning to malfunction. I've had this issue before and adding more refrigerant solved the problem. Remember to always use the appropriate type and amount of refrigerant for your Audi 80.

Inspect the compressor and related components for any signs of damage or leaks. Faulty compressors are a common cause of air conditioning issues. If you find any damage, it may be necessary to replace the compressor for proper functioning of the system.

Check the blower motor and its connections for any dirt or debris buildup. A dirty blower motor can affect the airflow and cause the air conditioning to malfunction. Clean or replace the blower motor if needed.
