Where is the fuse box located on the 2020 Ford Expedition?
The primary fuse box is located in the engine compartment, near the battery. Look for a black box with a removable lid. It may have fuse or relay labels on top or inside the lid, indicating which fuses and relays correspond to various electrical components. Some vehicles have a secondary fuse box located inside the cabin. It is commonly found in the driver’s side footwell area, beneath the dashboard. Again, it may have a removable cover with fuse and relay labels.
Precautions before changing the fuses
- Prior to servicing high-current fuses, it is crucial to disconnect the battery. This precaution helps prevent electrical accidents and ensures your safety.
- When replacing the cover of the power distribution box, be sure to do so before reconnecting the battery or refilling fluid reservoirs. This step reduces the risk of electrical shock, providing an added layer of protection.
- Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can lead to severe wire damage and, in extreme cases, may even cause a fire. To maintain electrical safety, adhere strictly to the recommended amperage for fuse replacements.
Note: The respective vehicle owner's manual will provide you with the most accurate and up-to-date information. It's important to go through owner's manual for the exact location and identification of the fuse box in your vehicle, as the location can vary slightly depending on the trim level or optional features.
