Ok, I am about to take the old shotgun to my back power window!! It has always been a big pain in the #ss, and it just keeps getting worse. It has always been a slow mover, but this past week, it now stops about 8 inches from the top on its way up??? It just stops with a "thunk", like it is hitting something on the way up...I was planning on taking the panel off the tailgate again this weekend, is there anything I need to check in particular?? It will go up and down just fine if I trip the tailgate latches and lay the tailgate down flat and support the window glass. But as soon as I close the tailgate and try it again, it just stops. It won't even go up with me "helping" it up (by grabbing the window and pulling it up). Anyone have any ideas?? I just greased the thing all up about a month ago to try to help it...it really sucks in the rain. By the way, if I pull and push the window (which is scary, it feels like it is gonna snap off!) enough while activating the switch, it sometimes goes up again...??????????
