I'm not sure what's up but the passenger side window on my Fiesta is real slow to go up the last couple of inches. It does close but it acts like the motor is weak or the track is very sticky. What makes me think it's the motor though is that sometimes it's fine, especially if it is being rolled up all the way. Roll it down 4" and then roll it up and it's quite slow. I haven't yet had the time to look at the window channel but if I don't see anything amiss it will be going into the service bay. Might try lubing the channel with some silicone spray first too, that always seems to help on my Miata.
