Optra rear ventilation faulty plug

Hi, I'm having a strange issue with my 2019 Chevrolet Optra with a gasoline engine. It has 61277 km on it. The rear ventilation flap seems to be faulty. I'm getting an error stored in the error memory, and the climate control unit seems to be malfunctioning. The air conditioning isn't cooling properly anymore. I suspect it might be a defective cable or plug connection. Has anyone experienced anything similar?

Summary of the thread

A 2019 Chevrolet Optra owner reported a malfunction with the rear ventilation flap, affecting air conditioning performance and storing an error in the memory. The issue was suspected to be a defective cable or plug connection. After consulting with another Optra owner who had similar issues, it was advised to seek professional diagnostics. The problem was confirmed to be a defective plug connection, which was repaired at a cost of 95€.

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?

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!
