To find the fuse for a specific power point (your PowerPoint, presumably a 12V outlet), you need to:
1. Consult your owner's manual: This is the definitive source. The manual will have a fuse box diagram showing the location and what each fuse controls.
2. Locate the fuse box diagrams: They are usually located inside the fuse box itself (under the hood and/or inside the vehicle's cabin).
3. Check the labels on the fuses themselves: The labels often provide clues, even if not perfectly matching "PowerPoint." Look for terms like "Accessory Power," "Cigarette Lighter," or similar.
If you can't find the fuse using your owner's manual, you can try searching online for a 2001 Ford Expedition fuse box diagram. Many websites provide these diagrams, often in PDF format. Be sure to specify the year and model as fuse box layouts can vary slightly.
