That's the key point, the zippers stay on the window and not the top. Try to pull down the zippers and back window at the same time. Make sure the window bar is unhooked too. Makes it much easierThe new premium tops must be easier as my rear window unzips and zips easily both off and on. I think you are at the point where you just need to give it a good tug down ward on the window. the zipper pulls stay on the window not the top.
Looks like it should be fine, unzip both to the drivers side and pull the window down. As has been said the zippers stay on the window, knowing that makes it much easier.There is 2 zippers ,just trying to figure out if I was unzipping on the correct side. This would be my first time taking it off and it just won't come off .
