I know this has been discussed before but I was hoping someone could point me in the direction of reference material or a good description of how to repair the issue. My window won't roll up or down but I can push it up or down. I can hear the motor running which leads me to believe that it is the gears that are stripped out. I'm ready to dive in and get it done but I don't want to do so blindly. So, where do I go and what do I do?
