My driver side power window does not going all the way up every time… sometimes it will go half way up or maybe just a few inches… If I let it sit for a minute or two and try again it will go either all the way or again, just a few inches.(almost as if it needed to charge the motor so that it can go up further) Do I need to install a new power window motor? Or, are there other factors such as the relay that I need to check?
First try cleaning and lubricating the window tracks. It might solve the problem.
