If the applicable fuse has a bare spot over each leg, no need to pull the fuse. If the fuse circuit shows to be hot all the time, just use a voltage tester on the bare spot over each leg, if both bare spots are hot, you know the fuse is good and there is voltage on the fuse circuit. Even if the fuse is good, if no voltage to the fuse, the circuit is dead. If you already checked all this, we'll try something else. The fuse in the diagram is for the power windows.
