chances are that it has nothing to do with a fuse because a fuse would control power to both switches, Unfortantly your probably looking at a more costly repair such as a power window motor, Your problem could also lie in the switch one way to determine that would be to first remove the swith from the panel and jump power from one side on the down side to the other and the window will go down if the power window motor is good if it does nothing you know that you more than likely have a bad window motor. They are not that bad to change you just have to drill out the rivets remove the motor and lift arms and then install new one get window lined up bolt new motor in place try toget one from a local scrap yard and save yourself some money!
