I've got a droopy wiper at the back. Tried to undo the nut to adjust but it seems pretty solid, gave it a good spray with WD40 and left it for a few minutes as well, doesn't want to move. Any ideas before I get a bigger spanner out and probably snap something?

Also the washer jet is missing from the end. I've seen some replacement washer jets and it seems to suggest you just push it in, is it that simple? If so, I'll order one.
