I have a 95 Altima. I just started having a problem with my passenger window. The window goes down fine. However, will not go back up. You have to pull on it while holding the switch in order to go back up. The problem only occurs when the window goes down past a certain point. If I put it down half way, it'll go back up fine. I'm afraid it will get stuck all the way down and never come back up. Is there a problem with the motor, or maybe the window is off of its track? Any help?
