Out in some heavy rain last night and my auto wipers have gone mental. One push up on the stalk puts them straight into constant, they run for about a minute and then park at a random location on the screen. pull the stalk down and instead of clicking off they will move until you let go of the stalk. then pull down again and they click off. up again and back to constant. Also when i engaged reverse the rear didn't wipe itself. They have done this once before over christmas when it was very cold, but an ignition restart sorted it. went out again last night and still doing it, and still doing it this morning. I am guessing CIM, thankfully car is under warranty, just wondering if other people have had the same thing?
