On my 2003 350z I have a problem where the window won't go back up once it goes all the way down. It will go up if I put down half way but once it reaches the bottom it wont go up. I have replaced the motor and regulator. The motor works by itself as I tested that it does rotate both ways. Also there is the same problem if intake the window out of the car and just use the motor to move the regulator. It doesnt go up when it reaches the bottom. I feel as if the motor loses power or doesnt have enough once it reaches the bottom. Any suggestion or does anyone have a similar problem?

If you did the reset procedure correctly, the window should move down when opening the door, and come back up, when closing the door.

How does the window motor sound when it works? If it sounds like it is 'struggling,' low pitched whining sound, then I'd say your window motor needs to be replaced.
