In this article, you will find information about the fuses of the Ford Expedition (models 1997 and 1998), including diagrams of the fuse boxes, a list of fuses and relays, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Ford Expedition
If electrical components in the vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken element. Check the appropriate fuses before replacing any electrical components. Use the fuse puller tool provided on the driver’s compartment fuse panel cover to replace the fuses.
Even after a fuse is replaced, it will continue to blow if the cause of the overload is not identified and corrected. If the fuse continues to blow, have the vehicle’s electrical system checked by a qualified service technician.
Caution!
- Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire.
- Always disconnect the battery before servicing high current fuses.
- Always replace the cover to the Power Distribution Box before reconnecting the battery or refilling fluid reservoirs.
Location of Fuse Boxes
Passenger Compartment Fuse Panel:
Power Distribution 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.
Relays:
Relays are located in the power distribution box and should be replaced by qualified technicians.
Primary Battery Fuses (Megafuses) (1998):
The primary battery fuses are located in the engine compartment near the battery. Ford recommends that the megafuses are serviced by a qualified service technician.
