How can I fix my Audi A3's malfunctioning AC?

I just noticed that my Audi A3's AC is not cooling properly. Even when I set it to the lowest temperature, the air coming out is still warm. What could be the issue and how can I fix it?

First, check if your AC compressor is working properly. If it is damaged or faulty, it may be the source of the issue. If that's the case, I recommend taking your car to a certified mechanic to have it fixed. Additionally, make sure you regularly clean or replace your car's cabin air filter to ensure proper AC functioning.
