In this article, you will find information about the fuses of the Ford E-150 / E-250 / E-350 / E-450 / E-550 (models 2002 and 2003), 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 E-150 / E-250 / E-350 / E-450 / E-550
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. To remove a fuse use the fuse puller tool provided on the fuse panel cover.
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:
The fuse panel is located below and to the left of the steering wheel by the brake pedal. Remove the panel cover to access the fuses.
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 are located in the power distribution box and should be replaced by qualified technicians.
