Ford F-150 (2004 – 2008) Fuse Box Location and Diagrams
The eleventh-generation Ford F-150 is a legend of reliability, but electrical hiccups like a dead power outlet or a flickering headlight are inevitable over time. Most of these issues can be fixed in minutes by simply swapping a blown fuse. This guide provides the exact location of the interior and engine bay fuse blocks for the 2004, 2005, 2006, 2007, and 2008 Ford F-150, along with detailed charts to help you identify the right circuit every time.
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.
Note: 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.

Passenger compartment fuse panel / power distribution box
The fuse panel is located under the right-hand side of the instrument panel. Remove the trim panel and fuse box cover to access the fuses.
To remove the fuse box cover, place a finger behind the PULL tab and your thumb above the PULL tab as shown in the illustration, then pull the cover off.
Auxiliary relay box
The relay box is located in the engine compartment on the left fender.
