[mickrochip]

thanks for your reply, i have changed motor now , but still it does work corectly
when wipers turned on to stesdy wipe it will do about 6 wipes across window an then stops in random positions .i then haveto turn switsh off an then on again to do the same thing it dosent matter if it is single speed or double speed or wash wipe it still does the same,is it possible that this is a relay or a switch problem
thanks for your help
