Hi all. New to the group here and i have a weird problem. My 2008 EB Expedition is havong window issues. I replaced the regulator / cable assembly because thr cable broke. Now when i roll the window up it hits the top then goes back down about 6 inches. It rolls down fine. I've searched the site but can't find any threads about windows going back down by themselves. Anyone have any ideas what is causing this? Thanks!!
