Have you tried the recal procedure? This is a carryover problem/feature from Mercedes parts that have the same issue. It can occur if you pull the #11 fuse a lot, usually after each time that is done. Other things cause the recal to be lost.

1) Roll window down and hold switch down all the way for 2 seconds.
2) Raise window and hold switch all the way up for 2 seconds.
3) Test. Auto up/down should now be OK.

Repeat for the other window.
