How to fix the Auto Climate Control on a Audi 80?

I recently purchased a used Audi 80 and the auto climate control feature doesn't seem to be working properly. When I set a specific temperature, it either blows out hot or cold air regardless of the setting. Is there a way to fix this issue or do I need to take it to a mechanic?

First, check to see if the temperature sensor is functioning correctly. This should be located near the dashboard and can sometimes become blocked, causing the auto climate control to malfunction. If the sensor appears to be fine, then you may need to recalibrate the system through the onboard computer.

Another common issue with the Audi 80's auto climate control is a faulty blend door actuator. This controls the direction of the air flow and can cause the system to blow out hot or cold air when it's not supposed to. It may need to be replaced by a professional.
