Corsa Defrost Flap Issue

Sounds frustrating! I had a similar problem with my old Renault Megane, although it was the temperature regulation that was off. Check all the fuses and relays related to the ventilation system before you start tearing things apart. It might be a simple fix!

Thanks for the advice. When you mention the temperature regulation, was that also throwing an error code? And did you notice any windshield fogging, or problems with air circulation generally?

Yes, there was an error code present. I didn't have fogging issues, but the climate control was definitely messed up. Honestly, after checking the basics, I just took it to a workshop. Saved me a lot of headache in the long run.

I appreciate your input. I will check the fuses and relays as you suggested. If that doesn't resolve the problem, I'll likely take it to a local shop. The estimated repair cost is around 95€, so hopefully, it won't be too extensive. Thanks again!
