* Your Owner's Manual: The most reliable source is your vehicle's owner's manual. It should have a detailed diagram showing the location of all fuse boxes (there's usually one under the hood and one inside the cabin) and what each fuse protects.
* Online Repair Manuals: Websites like Chilton.com or AllDataDIY.com (subscription required) offer comprehensive repair manuals including detailed fuse box diagrams. These are generally very accurate.
* Ford's Website: While Ford's website doesn't typically host full repair manuals for free, searching their site with "2001 Ford Expedition fuse box diagram" might yield some results, depending on their current online resources.
* Online Forums: Forums dedicated to Ford vehicles (like Ford-trucks.com or Expedition forums) may have members who have posted pictures or scans of their fuse box diagrams. However, always verify the information found in these sources as accuracy can vary.
Remember to always disconnect the negative battery terminal before working on any fuses or electrical components to prevent short circuits and electrical shock. If you're uncomfortable working with your vehicle's electrical system, it's always best to consult a qualified mechanic.
