Does anyone have any suggestions as to how I can remove the blades on the tailgate window. The front ones are easy but on the rear one there does not seem enough room to remove it in the same way. An easy task but obviously there is a knack that I do not know about.

Please does anyone have any suggestions as to how I can remove the wiperblade on the tailgate. The front ones are easy but there does not seem enough space to remove the rear one in the same way. Obviously there is a knack that I do not have.
