There is a procedure to re-teach the window the auto up/down feature. IIRC you lower the window completely and hold the down button for an additional ~5 seconds and then raise the window completely and hold the button up for ~5 seconds. You may need to do this for a couple of cycles for it to work.
I have never done this and may be completely off my rocker.
Let us know how it works.
I have also read the MY 97 does not have this auto up/down feature on the passenger side. Can anyone confirm?
