h all,my intermitent wipers are intermitent!!.........full speed wipes and parks ok,but the intermitant speed parks all over the place,thats what enables me to park in the up position in my pics..........is this the motor/gearbox/contact assembly or the relay at fault?

... :roll:
ALSO,are 500 blades shorter??? i cannot remember,and if so,do they fit 126 arms?
