Finally fixed my slightly sagging wiper.
No more manually adjusting it, just for it to slide back down.
Thanks for the diagram Marcos12.
I only had seen the diagram on how to remove the cover at the base.
I would only add after removing the cap and 10 mm nut, use a little liquid wrench on the thread (my arm wasn't going anywhere), use pliers and a rag to protect the wiper arm base, and pull up firmly.
