To find the specific fuse:
1. Locate the underhood fuse box: This is usually a black plastic box near the battery. The lid should have a diagram showing the fuse layout.
2. Consult the fuse box diagram: This diagram will show you which fuse is for the power outlet. The diagram will likely label it as "Power Outlet," "Cigarette Lighter," or something similar. The amperage rating of the fuse might also be listed (usually 15 or 20 amps).
3. Identify the correct fuse: Once you locate the correct fuse on the diagram, find the corresponding fuse in the fuse box.
Important Note: The fuse box diagram is crucial. Don't just start pulling fuses; you could damage other systems. If your owner's manual is still available, it will have the most accurate fuse box diagram. If not, you can often find a diagram online by searching "[Year] Ford Explorer fuse box diagram." Make sure you use the diagram specifically for a 1998 model. Different years have different fuse box layouts.
If you've checked the underhood fuse box and it's not blown, the problem might lie elsewhere in the power outlet's wiring. In that case, you'll need a qualified mechanic to diagnose and repair the issue.
