I have a 2007 Lincoln Mark LT same as a ford . It was dark and ice on the truck I wanted to push the interior light on and I pushed the power sliding window button by mistake . It moved slightly . I tried to shut it and it moved a little then stopped . I wish I could just shut it manually because I hardly ever used it .Some very skinny person ( probably a crack head ) came through that window and it's will not only open a little past half way . Anyway rifled through stuff from my truck . And he left my light on and my battery ran down . Too Much Information I know .

 

The motor is right behind the rear seat in the center. If you have a fold down arm rest its right behind it. They freeze up from time to time. I had my wife start the truck with me being in the back then had her press the switch to open the rear slider while she did I took a rubber mallet folded the center armrest down and tapped in the back of the seat where the motor is located and it started working again. I kept working it over and over it now will shut with some force. I now open it from time to time to prevent it from freezing up.
