Peugeot 508 climate control malfunction

I had a similar issue with my 508. Check the blower motor power supply and wiring harness. Electrical connectors are often the culprit with these electronic faults. Have you checked the relevant fuses?

Thank you for the suggestion. Could you please elaborate on which specific electrical connectors I should be inspecting and where they are located? Any advice would be greatly appreciated.

In my case, the connector for the blower motor resistor was corroded. It's located near the blower motor itself, behind the glove box. Honestly, though, considering the symptoms and the fact that there's an error stored, it's probably best to have a workshop diagnose it properly. Could save you a lot of time and frustration.

I appreciate your advice. I took the car to a workshop. As suspected, it was a defective plug connection. The repair cost was 95€. Thank you for pointing me in the right direction.
