Movano rear ventilation flap issue

Hmm, rear ventilation flap issue on a Movano... I haven't personally seen that exact problem. But it's strange that it impacts the entire AC system. Are you absolutely certain the front is blowing cold? Did you check the fuse box?

Yes, I've confirmed that the front is not blowing cold either. I've also checked the relevant fuses, and they all appear to be intact. Is it possible that a fault in the rear ventilation flap circuit could somehow disable the entire air conditioning system, including the front?

Well, anything is possible with modern electronics. It does sound like a weird interaction, but I would say that if the error code specifically points to the rear flap, it's more than likely the source of your problem. I recommend you visit a workshop and have it checked professionally.

Thanks for the insight. I appreciate you confirming that such a fault could cause the entire system to shut down. I'll take it to a workshop. It ended up being a faulty connection as suspected. Repair cost was 95€.
