Skoda Octavia Defrost Air Distribution Problem

I am experiencing issues with the defrost air distribution flap on my 2019 Skoda Octavia with a gasoline engine (mileage: 52838 km). An error is stored in the error memory, and the heating output is insufficient. Based on preliminary diagnostics, the likely cause is a defective cable or plug connection to the component. Has anyone encountered a similar problem with the ventilation system or heater core in their Octavia?

I had a similar issue with my Octavia's ventilation system. The windshield was constantly fogging up, and the heater output was noticeably low. Did you check the blower motor resistor? Sometimes that can cause air distribution problems even if the blower motor itself seems to be working fine.

Thank you for the suggestion. The blower motor itself appears to be functioning correctly across all speed settings. Could you elaborate on the specific symptoms you experienced related to the air distribution? Was it only affecting the defrost setting?

Yes, the defrost setting was the most affected. It felt like very little air was actually being directed to the windshield. If your blower motor is fine, and you suspect a wiring issue, it might be best to have a workshop take a look. They have the tools to properly diagnose those kinds of electrical problems in the air distribution system.

Understood. The defect was indeed a faulty connection, as suspected. The repair cost was 95€. Thank you for your input.
