GLC Sunroof System Failure After Coding Sunblind Stuck

I had a similar issue with my GLC's sunroof system. The sunblind got stuck, and the whole sunroof operation went haywire. Did you check the basic stuff like fuses related to the sunroof control module? Sometimes a simple fuse replacement can resolve these glitches. The sunroof mechanism in these cars can be quite sensitive.

Thanks for the tip. Which fuse exactly did you check? I've got a 2020 GLC hybrid and after some coding, the sunblind is stuck, and the convertible top is completely unresponsive. I suspect it's related to the coding, but I want to rule out simpler causes first.

Honestly, I can't recall the exact fuse number. I just took it to the workshop. They said the sunroof mechanism needed recalibration after the coding messed things up. Sounds like the same thing that happened to your car sunroof. I would suggest you go to a workshop and have them check. It's probably not worth the hassle of trying to fix it yourself.

Yep, you were right. Took it to the workshop, and they recalibrated the sunroof control unit. Turns out the coding scrambled some parameters. Cost me 75€, but everything's working fine now. Thanks again for the help.
