So another interesting second level problem with this is that if the window motor or mechanism fails, you can't use the door at all. I have had window mechanisms fail and had to pop the cover off the door to get it back into place, but in this case you can't get the door open to get in there without breaking the window. So as far as I can tell if the window motor or mechanism fails, you will lose the window if you ever want to use the door again.
