(i think) From OFF POSITION

1 click down is ittermittant
1 click up is medium
2 clicks up is uber warp speed wipers


is that what your after? or where you wondering if there was a variable pot to control the intermittant wipe speed. (which there isnt one)
 
is this not a wasted question, something that could have easily been found out by a tiny bit of playing around with the stalk :shrug:
 
On the subject of stalks, what's the clicky in-out button on the end of the wiper stalk for? Mine doesn't seem to do anything and hasn't done since I got the car.
