Thanks for the suggestion! I did check the fuses, and they all seem to be fine. So, the AUC sensor fault was also present with your Megane? Did replacing it resolve the issue completely?

Affirmative. The sensor fault was indeed the root cause. Considering your Honda's age, I would recommend a visit to a qualified workshop for a thorough inspection. They possess the diagnostic tools to pinpoint the exact nature of the malfunction.

You were right! Took it to a shop. The AUC sensor cable was faulty. New cable and sensor total cost: 95€. Thanks for pointing me in the right direction!

Good day, I experienced something similar with my old Renault Megane. The air conditioning would not function. Have you checked the relevant fuses? It's frequently the simplest solution.
