Could be. Had similar on a 2016 Opel Astra. Air distribution was all messed up. Blower motor seemed fine. Did you check the dashboard panel for obstructions?

Checked the panel, nothing obvious. How did you finally fix the Astra's ventilation system?

Turned out to be a dodgy connection. Climate control unit was throwing codes. Best to check with a workshop to pinpoint the exact wiring issue.

Cheers. Shop confirmed cable issue to the air distribution flap. Repair 95€. Thanks for the tip.
