Fuusraum passenger side permanently cold

Hello municipality. Have above mentioned vehicle with which on the passenger side permanently kale air comes. For me it looks as if the flap adjustment no longer works. Maybe you can take the climate control once resets like with my Opel or there is for it a separate spare part which can then be exchanged or is this a larger act for repair e.g. kpl. blower immerse 😉 Thank you.
