Ford F-250 (2017 – 2019) Fuse Box Location & Diagrams
In this guide, we cover the Ford F-250 (2017–2019) fuse box diagrams and locations, helping owners quickly identify fuses, troubleshoot electrical issues, and maintain their vehicle’s electrical systems efficiently.
Fuse Box Locations
Passenger Compartment
The fuse panel is in the right-hand side of the passenger footwell behind a trim panel.
To remove the trim panel, pull it toward you and swing it away from the side. To reinstall it, line up the tabs with the grooves on the panel, and then push it shut.
Engine Compartment
The power distribution box is located in the engine compartment. It has high-current fuses that protect your vehicle’s main electrical systems from overloads.
WARNINGS
Always disconnect the battery before servicing high current fuses.
To reduce risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs.
