Although I'm a newbie! to here would appreciate some help I've searched this problem but couldn't find anything. The rear wash wipe on my Avant has stopped working the motor works good and strong and the fronts work. The water from the rear just dribbles out I've blown the nozzles and stuck a pin in no change. I can't see any wet patches in the boot and checked the tailsgate, nice and dry so is the head lining. Where is the likely problem to be?
