It appears that my rear wiper blade needs replacement, a more difficult task than meets the eye.
After playing with it for a bit, I removed the cover at the base of the hub (where it connects to the drive) this enabled me to lift the blade perpendicular to the window. I was then able to remove the entire arm with the blade attached. However it appears to be a special type of set up with the way the arm attaches to the wiper assembly.
Has anyone else had to do this yet ? Any tips and tricks welcome
