I just had a free sliding window problem. No up or down but the motor runs. I took it apart. The familiar (mentioned a lot on this forum) plastic/nylon slider is broken in two. I slid it right out the end. Do I just get a new one and slide it back in and reinsert the scissors jack type thing? Or is there some part I am missing that stops the plastic slider from sliding out of the track. Or does the window travel keep the piece from sliding out the end.

I am trying to order parts and don't want to just order the slider if I need more. ...JR
