The manual will have a detailed fuse box diagram showing the location of each fuse and what it controls. The diagram will typically show several fuse boxes: one in the passenger compartment (usually under the dash) and possibly one under the hood.
Without your owner's manual, the best advice is to carefully inspect the fuse box diagrams you can find online (searching for "2001 Ford Explorer Sport fuse box diagram") and compare those diagrams to the fuse boxes in your vehicle. However, always cross-reference this with your owner's manual for accuracy. Remember that different online diagrams may not be entirely accurate for your specific vehicle's configuration.
Important Note: Before touching any fuses, turn off your vehicle's ignition.
