Yes, the air distribution is definitely affected. The rear passengers barely feel any air. Regarding diagnostics, I only checked the error memory using a basic OBD2 scanner. What kind of diagnostics did you perform when you had a similar issue?

Okay, that sounds very similar to what I experienced. I didn't do much myself beyond checking the obvious fuses. Eventually, I had to take it to a workshop for proper diagnostics. They found a problem with the rear ventilation flap control. It's probably best to get it checked professionally to pinpoint the exact cause.

Thanks for the advice. I'll take it to a workshop and have them check the rear ventilation flap control. Turns out it was indeed a defective plug connection, just as I suspected. The repair cost me 95€. Thanks again!

I also drive an Optra. I remember having some issues with air circulation a while back. Is the air distribution affected, especially for rear passengers? Have you run any system diagnostics besides checking the error memory?
