Citroen C8 Solar Sensor Fault

I had a similar issue with my C8. Is the sensor the HVAC sensor? The symptoms sound familiar. Is the air conditioning performing as expected?

Yes, I think it's the HVAC sensor you are talking about. The air conditioning seems to be working, but I haven't tested it thoroughly, as the heating issue is more prominent. Do you remember any details about your case?

Yes, it was definitely the solar sensor causing the heating issues. If the AC is working, it's likely the sensor is faulty. I recommend getting it checked at a workshop, as the cable and connections might be the problem.

Thanks for the info. I had it checked, and indeed, it was a defective connection at the sensor. The repair cost me 95€. Everything's working perfectly now.
