I have a leaf 2013. A piece of cloth got trapped into the back door lock, and now the door would not open. This is the second time this happens and it cost me 160$ last time I had it fixed, I know there is a manual lock somewhere we can access from within the trunk, but I don't manage to locate it, much less to access it. I saw this video https://www.youtube.com/watch?v=IWZnio-o7F8, but the little plastic door the author opens is not present on my model. Any suggestion?
