If your other windows are working, it's not a fuse, all the windows come from the same source. Is there any evidence that the motor is trying to move the window, such as hearing a humming or the lights dimming when trying to raise or lower it? The switch should have 3 wires going to it, one for up, one for down, and common or hot. Verify that one of the wires has 12 VDC, that is your hot or commonn, remove that one and test between that and either of the other two terminals with your meter with the meter set on resistance (ohms). Rock the switch in up or down and see if the continuity on the switch goes to near zero. If not, try the other direction. Resistance going to less than one is good. If that side passes, place your meter across the other terminal and the common, repeat. If both directions pass, start checking for grounds. When the rocker switch for raising\lowering the window is in the neutral position (the middle), check each of the two terminals that you checked to common to a good ground. You should have some resistance, maybe 5 ohms, but not much. If one leg is much higher than the other, you either have a broken wire from the switch to the motor or a bad motor. If resistance is equally high on both legs, it's probably a bad ground.
