You will most likely need to replace the window switch(s). The rocker inside the switch is shorting out. The switch has two s-shaped copper like strips that breaks or get out of position. The switch is not terribly expensive. The switch circuits are in series and all need to be connected for each to work. (at least on 85.5)). Just need to figure out which is the faulty switch. A fault switch will cause the window power fuse to blow as soon as there is power to the circuit with a servicable fuse installed.
