Thank you so much for all the work you put into this!
I now think that us models may be different than eu models. Because yesterday i opened my burned wiper motor. And found out that it is constructed to stop higher on intermittent. Look at the picture and there are 3 circles with different contact intervals.
1. Inner circle is the parking for normal wiping 2, 3 and one swipe.
2. Mid circle is for giving message back to relay for both inner and outer circle.
3. Outer circle is for intermittent 1 and wipe flush parking. When it gets contact the relay turns off.
So if you compare inner and outer circle you can actually see that the outer circle will stop a little later than inner circle. Inner circle stops when it loses contact and the outer stops when it gets contact.
Did you try the intermittent one click up on stalk? Because thats the one that stops higher on my model. Normal wiping and one swipe stops all at the lowest on mine to.
