Skoda Citigo Blower Problem
Summary of the thread
A 2014 Skoda Citigo experienced a blower motor failure, with the climate control panel still lighting up but no air output. A diagnostic scan revealed an AUC sensor fault, which was suspected to be the cause. It was suggested that a faulty AUC sensor or its connection could disable the blower. After checking, a faulty connection to the AUC sensor was identified and repaired, resolving the issue.

Interesting, so the AUC sensor can actually stop the blower entirely? I thought it just controlled the auto recirculation. Where exactly did you find the problem with your BMW AUC?

Yes, in my case, a faulty signal from the cabin air sensor caused the entire climate control system to shut down as a failsafe. The exact location of the connection issue on my BMW was right at the sensor itself. However, I would suggest taking it to a workshop for diagnosis.

Right, after a bit of back and forth with the garage, they found a dodgy connection to the AUC sensor, just like you said. Blower's working again, and the climate control seems fine too. Cost me 95€, so not too bad. Thanks again for the heads-up!

This sounds very similar to an issue I had with my BMW. The auto recirculation (AUC) sensor went bad, and it completely disabled my climate control blower. The BMW AUC sensor is an odor sensor which is part of the climate control. Have you checked the cable and plug connection of the component? It may be defective. I'd start there.
