driver side window motor

I have managed to unscrew the window motor from the driver side window but I am unable to get it pushed back up into the regulator. It will go up until it starts to hit the threads. I wonder if there is a trick to "spin" the threads so it can slide the rest of the way up into the regulator. Thanks for the help, windows out and it raining in Iowa.

Been there, jiggle and shove, while pressing gently down on the window itself.

Note: The first time I tried to put this thing back together, in desparation, I pressed it together as much as I dared, hooked up the wire, threw the key, and pressed the window button (down). The unit jumped right into place. In hindsight though, I realized that all I had to do was push up on the motor while pressing down on the window pane, to draw the motor into place.

Live and learn.
