why do the wipers on my vivaro van stop in the wrong possition on the winds?

if crank arm on motor is fitted with a nut then it may be possible to re-position them .with wipers switched off and in their [now ] parked position,undo crank nut on wiper motor -it may be on a splined taper fitting]-reposition wipers to bottom of screen and re tighten crank nut. should now park correctly [dont try to reposition arms or you may find them trying to wipe bonnet!]. MAKE SURE IGNITION IS OFF WHEN MESSING WITH WIPER SYSTEM THEY ARE VERY POWERFUL AND YOU DONT WANT TO GET FINGERS ETC CAUGHT UP IN LINKAGE
