Thank you so much.
Worked like a charm for me on the second try.
I did not hear any beeps, I did accept the inital warning that comes on when you start the car, and go into service codes to see the actual "anti-trap" error when I performed it for the second try.
Also I believe you CANNOT sit at the driver side to perform these unless the driver side window is the one with the issue.
Here were my steps...
1) I had the car started
2) Roll down the window all the way from the "broken" window (it wants to stop every xx inches, keep making it go down all the way)
3) I released the switch
4) I pushed and held down (I heard from another place that it needs to be exactly 17 seconds)
5) After 17 seconds I immediatly pulled up on the switch to roll the window up (it went all the way up).
6) after the window went all the way up, and still holding the up switch, it rolled all the way down, and then all the way up once more.
7) After #6 the process was complete and the window was functioning normal again.
Hope that helps.

17sec is working but didn't solve the problem

After 17sec it went all the way up (which normally it doesn't so the 17 sec is working), and it came down about 10 CM again. not completely down!
so my actual problem is that I'm getting the "window anti-trap function failure" error and the window needs multiple pushes on the button to go completely up or down!
Now my question is Should I reset the window's position first, and then reset the error, or reset the error first?
And now with resetting the position, holding the button is 3 seconds, 5sec, or 10sec? because there isn't a clear instruction out there or I couldn't find the right documentation for it!

Some instructions state to hold the button 15 seconds, others state 30. I do not recall having to hold the button that long. If you are still unable to re-calibrate, you may have a bad motor, or something is lagging the regulator travel.
