Which fuse controls the power windows?

The window could possibly be catching on something inside the panel (but not off track), but it is most likely the power window motor. Local auto parts stores should be able to supply you with one, or at least the part number. I usually look for parts like this on ebay once I know which part I need. Removing the interior panels to get to the motor can sometimes be tricky. If you search something like "Remove Escort door panel" on Google, you will probably find that somebody, some where has published a step by step guide.
