I just had to do this to my 1998 wagon.

1) Press the UP one click (not all the way down) hold for a second.
2) Press the DOWN one click (not all the way down) and hold until the window is down.
3) Press the DOWN all the way and hold for a second.

Then try the Express Up feature - worked for my wagon.
