Welcome to the Forum
Stu is on the right track but when you push the button on the end of the stalk and the green light is on that is the rain sensor enabled, wiper should then operate when the sensor is obscured by water on the screen, just either spray water or sprinkle some on the screen. A single click down intermittent two clicks up for full operation and high speed a push towards the dash is intermittent rear wash wipe push towards the dash and click should give full rear wiper operation
