... the side hatch jams at a certain point in its travel ... it seems in the central rail ... I tried to clean but it hasn't improved ... it wanted to dismantle the rail cover ... I guess there are two screws, one on the upright and one under the rear light ... I removed the light screws but I can't disassemble it ... I don't want to do any damage ... does the light pull out? ... to the side? .. . once you have unscrewed the screws of the rail cover do you just have to pull it out or something else? ..... thanks
