That description is real confusing. Exactly what are the symptoms? It sounds like the interior lights are staying on unless you unplug the fuse. If that is right, the fuse box is doing what it is supposed to do which is supply the 12 volts to the lights. It's the door switches that ground the other side to turn the lights on.
If you have a short in the voltage supply side, you'd be blowing fuses. A short in the ground side, (or switch that isn't turning off), causes the circuit to turn on when it's not supposed to.
