The most likely culprit is a dirty switch. If the motor will roll the window down, it should roll it back up again. Go to Radio Shack, get some Contact/Control Cleaner Lubricant. Spray copious quantities into the switch at the door and in the center console switch pack. Exercise the switch while you are doing this. No need to remove either the switch or center console to do this, as it will not gain you any better access to the switch. This has fixed the same problem with my windows. Fix has been in for at least six months now, with no recurrence.
