In this article, you will find information about the fuses of the Ford F-250 / F-350 / F-450 / F-550 (models 2005, 2006, and 2007), 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 F-250 / F-350 / F-450 / F-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 disconnect the battery before servicing high current fuses.
- Always replace the cover to the passenger compartment fuse panel before reconnecting the battery.
- 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.
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. To remove the fuse panel cover, pull the panel downward by the finger slots on top of the panel. When the top clips of the panel disengage, let the panel fall easily.
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:
An auxiliary relay box is located in the left-hand front side of the engine compartment. This box contains relays for the Electronic Shift On the Fly (ESOF) system. Please see your authorized dealer for troubleshooting or service of these relays.
