How to diagnose and repair a malfunctioning climate control in an Audi 80?

My Audi 80's climate control system is not functioning properly. What could be causing this issue and how can I fix it?

It is likely that the issue is with a faulty sensor or a broken electrical connection. In order to properly diagnose and repair the issue, it is recommended to take your Audi 80 to a certified mechanic with experience working on this make and model.

One possible cause could be a malfunctioning blower motor, which is responsible for pushing air through the vents. You can try checking and replacing the blower motor yourself, but it is highly recommended to seek professional assistance to ensure proper installation and avoid causing further damage.

Another potential cause could be a problem with the compressor, which is responsible for regulating the temperature of the air. If this is the case, it is best to take your Audi 80 to a mechanic to have the compressor checked and potentially replaced.
