Help please. Window doesn't clear top

[358Ron]

I'm having the same window problem on my 2003 Boxster S. Only on the passengers side. Just started this past weekend. I'm going to lower the window and raise it and hold for 5 seconds with door closed, ( as advised here), and see if this works. I can manually raise and lower the window at this time. It just doesn't jump down when I pull on the door handle like it did before. When I try to close the door the window is too high, for door to close. Does anybody have any other suggestions if this procedure I'm going to try doesn't work.
