Bipper sun blind issue

I also have a Bipper, not the exact same year, but your issue sounds familiar. When you say 'stuck,' is it completely immobile, or does it move a little and then stop? Have you checked for debris?

By 'stuck,' I mean it is completely immobile. I checked for visible obstructions, but found none. Is the motor easily accessible, or is dismantling required?

If it's completely immobile after checking for obstructions, then the issue is likely the motor, as suspected. Accessing the motor requires some dismantling of the headliner trim. Unless you are experienced, I strongly suggest a workshop. The repair cost for me was around 330€, so be prepared.

Thank you for confirming. I will schedule a workshop visit. I appreciate the advice.
