Hello! When I first bought my s3 the wipers were always a little dodgy. After first moving the stalk to engage the wipers they would always struggle to get moving, but after a second or so they would be fine. Yesterday I was driving In the pouring rain and all of a sudden the wipers just stopped bang on in the middle of the screen, a quick push with my hand out of drivers window soon got them going again. But today they just won't budge no matter where the stalk is set. Anybody had any similar issues and managed to resolve it ? Thanks.
