So on my 91 q45 the wipers, in intermittent mode, will go to the top and stop then to the bottom and stop.
And the delay plays into this as well for example if I have it to like 5 seconds
Wipers move to the top. Then 5 seconds later move to the bottom.
Doesn't matter the speed.
But low speed and high speed works fine.
Also it doesn't park fully...
Any ideas what to look into?
