My windscreen wipers when turned off sit about 6 inches up the windscreen , dont go into park mode . They operate normally throughout the wiping range and throughout the three speed settings , but when u turn them off or when in intermitent mode they stop 6 inches above were they should . If u manually push it to the park position it will set off for another wipe and stop short of the park position again . Can anyone shed any light on this problem. A mercedes mechanic has quoted me 500 aust dollars to put a second hand one in. Cheers Tony
