This happened at random the other day, rear wiper done a complete sweep but instead of finishing there it partially came up again & stopped half way up the screen, when i tried again, it either done the same but sometimes won't work at all. If i just leave the wiper 'on' it'll eventually work but it's luck as to whether it stops at the bottom or not.
I wonder if this a relay fault, or is it a stepper motor & is that faulty ?
