Mercedes SL rear ventilation flap problem

My 2005 Mercedes SL with a gasoline engine has a rear ventilation flap issue. The error memory shows a fault, affecting the climate control, and the AC isn't cooling. I'm thinking it might be a bad cable or plug. Has anyone else dealt with this? I think the repair will be around 95€.

That's annoying! I had climate control problems in my SL last year, with messed up air distribution. It turned out to be the flap actuator. Have you checked that? It might be worth a look before you assume it's just the wiring.

Thanks for the quick reply. I appreciate the flap actuator suggestion. Could you give me more details on how you checked the actuator? I know a little about HVAC repair, but more info would help.

I'm not that technical. My AC was blowing hot air, so I went to a shop. They found a faulty flap actuator and some wiring issues. Based on what happened to me, you might want to get professional help to avoid making things worse. Good luck!
