* Under the dashboard, on the driver's side: This is the most common location. You'll likely need to partially remove or pull away the lower dash panel (sometimes near the steering column) to access it. There's usually a small cover or access panel that needs to be removed. Look for a small panel that is either hinged or held in place by screws or clips.
* Under the glove box: Less common, but possible. You may need to fully or partially remove the glove box to access the fuse box.
To access it, generally follow these steps:
1. Find the location: Check your owner's manual. It's the best source for the precise location and any specific instructions for your vehicle. The diagram should show the location and identify the fuse box.
2. Prepare to access: If it's under the dashboard, you'll likely need a small flat-head screwdriver or trim removal tool to pry loose any panels carefully. Be gentle to avoid breaking any clips.
3. Remove the cover: Once you've located the access panel, carefully remove it. Some covers are simply pulled off, while others may have screws or clips that need to be removed.
4. Access the fuses: Once the cover is removed, you should have access to the fuse box.
Important Considerations:
* Always disconnect the negative terminal of your battery before working with electrical components. This is a crucial safety precaution to prevent shorts or accidental shocks.
* Take a photo of the fuse box before you start working. This helps you remember the location of each fuse and makes it easier to put everything back correctly.
* Use the fuse box diagram in your owner's manual to identify the correct fuse.
If you can't find it after checking these locations and your owner's manual, a search online for "2003 Ford Expedition passenger compartment fuse box location" along with images might help. You could also consult a Ford dealership or a qualified mechanic.
