Not a super technical question (I feel silly for having to ask), but has anyone had to replace a weather belt (in my case rear passenger door) on their Liberty? The original trim piece on mine was starting to break apart, so I ordered a new one and figure it just pop right in (the is the horizontal piece of trim about the door handle). The front of the new belt is tight to the door and won't lift at all, but the back of the belt lifts up, and there is some separation between the belt and the door. Does anyone have an idea as to what I might be missing? Does the little tab between the glass need to be bent down or pulled up perhaps (with my luck I'll break it off if I just start pushing on it). Any ideas would be great.
