The exact location of the passenger compartment fuse panel varies slightly depending on trim level, but it's commonly found either under the dash on the driver's side or in the center console.
To find the correct fuse:
1. Locate your fuse panel: Consult your owner's manual. It will show you exactly where your fuse panel is located and include a fuse diagram. This diagram will tell you which fuse is for the power outlet (cigarette lighter). It's often labeled as "Power Outlet," "Accessory," or something similar.
2. Check the fuse diagram: The diagram will show you the fuse's amperage rating.
3. Remove the fuse: Use the fuse puller provided with the vehicle, or if one isn't present, a small flathead screwdriver, to carefully remove the fuse.
4. Inspect the fuse: Check if the fuse's internal wire is broken. If it is, replace it with a fuse of the same amperage.
If you can't find the information in your owner's manual, you can try searching online for a 1997 Ford Expedition fuse box diagram. Many websites and forums dedicated to Ford vehicles will have these diagrams readily available. Be sure to specify the year and model of your Expedition for accuracy.
