Exclamation The large rear window sunblind stopped working altogether!?

Hello,

The rear window blind came down by itself when the car was running stationary and wouldn't go up again after pressing the buttons (which are on the rear door armrests, I don't have any button for this blind in the front).
So from it no results, no noise, nothing but silence. 😕

On Primavera - I don't know which fuse where to look for and if only one is responsible for it or the other 2 side blinds on the rear side windows.
As a second thought, I don't know where the motor is in the trunk and where the blind is retracted/winded up. It might have tripped over something, but there would have been a sound trying to unfurl.
Or the problem could be more serious and probably expensive.

Anyone who has had their sunshade serviced, or has an idea what this issue may be please help. I appreciate any tips, tricks, and ideas on what to try to do myself or take to the Service

the * button (favourite) on the front comand knob panel, is usually set to do the blind - but can be set to do other stuff - otherwise in the vehicle comand menu is the choice to operate the rear blind
as for the rear - whilst fiddling did someone disable the rear buttons via the drivers door switch panel

If you have a good scanner you can activate it from the scanner to rule out the button issue. I know on my youcanic scanner I can go to Rear SAM control unit then active tests and operate the rear sunscreen. First check the fuses though, then go to the next diagonstic step.

It works great after pressing * (FAV).
It goes up and down repeatedly whenever I want.
I've seen the button, but never paid much attention to it, though it sits next to my right hand in front of the armrest.
You are a great person @BOTUS, save me daily headaches!
Be alive and well, such a small thing, I would complicate my routine with fuses, batteries, and even the mechanisms and motors of this blind...
