Ford Explorer (2002 – 2005) Fuse Box Location and Diagrams Guide
Fuse box locations and diagrams for the 2002–2005 Ford Explorer are here. These images and instructions will help you confidently identify and replace the right fuses for electrical issues or normal maintenance.
FUSES AND RELAYS
Fuses
If electrical components in the vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken wire within the fuse. Check the appropriate fuses before replacing any electrical components.
Passenger Compartment Fuse Box
The fuse panel is located below the instrument panel on the driver’s
side.
Engine Compartment Fuse Box
The power distribution box is located in the engine compartment. The power distribution box contains high-current fuses that protect your vehicle’s main electrical systems from overloads.
Auxiliary Relay Box
The relay box is located on the front right fender well underneath the speed control module.
