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

I've been experiencing issues with my Audi A3's AC constantly blowing hot air. It works fine for a few minutes, then suddenly switches to hot air. What could be causing this issue and how can I fix it?

There could be several reasons for this issue, Samantha. It could be a problem with the AC compressor, a leak in the AC system, or a faulty temperature sensor. I would recommend taking your car to a certified mechanic to diagnose the problem and provide a solution.

Make sure to check the AC refrigerant levels, Samantha. If they are low, it could be causing the AC to blow hot air. You can also try cleaning the AC condenser with a soft brush to remove any debris that may be blocking the air flow.

I had a similar issue with my Audi A3's AC, Samantha. It turned out to be a faulty AC pressure switch. I would suggest getting it checked and replaced if necessary.
