Before I dig into this, I thought I'd check to see if anyone has had a similar issue. I've done a cursory search and seen it's easy and fairly inexpensive to replace the window motor, and I have instructions on how to "reset" the windows but I think that's really for issues with the auto feature.

Symptom: Front passenger window will not go all the way down (stops about half way). When the up-button on either the driver or passenger door panel is actuated, the window goes up to about one inch from fully closed, but then goes back down. Occasionally if you continue actuating the up-button, the window will remain up at that point where it is one inch from fully closed, but usually once you let go of the up-button, it goes back down to half open.

I'm guessing something in the jam-safety system, but I don't know how that works. Are there sensors?
