How do I fix my Audi 80's faulty air conditioning?

My Audi 80's air conditioning is not functioning properly, and it's becoming increasingly uncomfortable to drive, especially in summer. I'm not sure what's causing the issue and I don't want to take it to the mechanic just yet. What should I do?

Check your car's cabin air filter, it could be clogged and preventing proper air flow. You can either clean or replace it, depending on how dirty it is.

If your air conditioning is still not working after checking your filters, it could be a problem with the compressor. Take it to a mechanic to get it checked.
