I am guessing the window motor for the window, which has brushes on it, to make contact so the motors shaft can turn, have worn away from the contact area and make enough of a connection to lower the window, but not raise it....... Had this problem with the Vr4 because it was a shitty ass recall.. I had to get new brushes put on, then come to find out the dealer changed me out a new one anyway.... But My window would sometimes do that, at the hospital, it got stuck completely down and it wouldn't go up for squat...
