Hi,
I have a 2016 428i Conv (F33). The passenger rear window is not going up at all (nothing happens when I pull the switch to open it/no noise either). It used to work fine, but it suddenly stopped working. This is also keeping the roof from retracting. I don't know why the roof wont retract; the window is all the way down.
Please let me know if you guys think this could be a fuse problem or a bad switch.
Thanks!
Lou

Had similar issue. If you are lucky it may just be a fuse. I needed a new assembly You can also try enet ista it should show an error and you can have ista do a reset on the regulator and motor.

See my thread on the issue for resolution

Thanks for the good info!
Did yours make any noise? Mine doesn't make any noise at all. I don't have the scan tool. Do each window regulator need/could use a reset?
Thanks!

Yes mine was real bad made a noise letting me know the motor was working but the window was freely moving.

Check fuses hopefully that’s all you need to do

Did you ever find this problem? Mine stopped working and now works intermittently. Stops my convertible top from moving when it’s acting up. Sounds fine when it works properly. No sound at all when not functioning.
I checked for drain plug issues, but drain plug had been removed by previous owner. Maybe that’s a clue.
