Hi Anyone know which relay is for the intermittent / wash wipe on a 1999 polo, since mine isn't working and relays are not identified in the owners manual. I've just changed the wiper stalk to no avail so I don't want to spend any more without fully diagnosing the fault. Also I have a relay noise when the car is in motion coming from the relay area, it stops when the car stops moving. Anyone with any ideas welcome. Thanks
