Disconnect the car's battery. With a multimeter on resistance setting, connect one probe to the 12V bus of your fuse box. The 12V bus is the strip that connects 12V from your battery to one end of all of your fuses. Now, one at a time, touch the OTHER probe to the OTHER ends of the fuse holders. The OTHER ends of the fuse holders should NOT be connected to eachother. They should lead to their individual circuits. The circuit which has the lowest resistance reading(10 ohms or less usually) will be your culprit.
Now from your fuse to where your short is located could be along several feet of wire. Gutting your car to find the short might not be in your best interest. What you can do is sever the connection from the fuse to the circuit, and run a completely new wire from your fuse to whatever device is powered by it. This will ensure that the short is out of your circuit.

Use a multimeter. You can use the ohms setting if there is no power on the circuit. It would help to get a wiring schematic to help identify the wires.
