I have a problem with my washers / intermittent wipers which comes and goes, typically as MOT is due in a few weeks it has suddenly got worse...I am 99.9% sure it is due to the stalk, especially the intermittent switch as can get them working again if I fiddle with this at times.Basically when it decides to play up I lose my washers totally and intermittent changes to single wipe position (confirmed with vagcom and in real world situations) when in intermittent they are just classified as off st
