The window needs to be taught again how far UP is. You have to hold the
manual up button continuously through an entire UP cycle. This will teach
the window controller how far UP is, then the Auto UP feature will work
again.

I've not got any electrical info on these but most use current sensing to
cut off the motor at the end of travel - when it stalls the current goes
up. Can't see any reason to do it differently but would love to hear if
I'm wrong and how it does work.

I'll admit that I don't know how it works, but I do know that it has to be
trained by holding the Up switch for the entire up travel before the window
knows how far up is, then will go up by itself.
