That's more or less whats happening with mine, except when the window is at the bottom. When I pry to release the bind on the gears, I can see the row of gears twist inward towards the door. I guess I'll continue throwing regulators at it, if the issue persists I'll see about making a rubber window stop.

Thanks again for the information
