Rear window shade worked fine until it was in retracted mode today. Now it is stuck inside the rear seat. When I push the button to activate it only clicks. No movement.

Jimmie Jaye Wells, Check to see if anything is blocking it and perhaps you could give it a gentle helping hand as a 2nd person operates the control. It could be a few things, activator, fuse(if you hear motor,fuse OK),plastic gears for up/down function misaligned/clogged/jammed or motor for shade operation faulty. If it is a bad motor, you may want to consider just having the window tinted and save a lot of cash as it is a very expensive repair. Below are some forum links that also discuss the issue. Good luck. I hope this helped you out, if so let me know by pressing the helpful button. http://mechanics.stackexchange.com/questhttps://mbworld.org/forums/c-class-w203/
