Quick Answer

The 2004 Ford F-150 has two main fuse boxes: one located under the hood and the other inside the cabin. These fuse boxes house all the fuses and relays for various electrical components in the truck.

Important fuses to know about:

  • Power Windows and Locks: If your power windows or locks aren't working, check the fuse in the cabin fuse panel. It's typically a 20-amp fuse.
  • Radio: For radio issues, look for a small 7.5-amp fuse in the cabin panel.
  • Headlights: These are usually controlled by a 15 or 20-amp fuse in the engine compartment box.

To access and check these fuses, open the respective panel, locate the specific fuse using the diagram provided on the cover or your truck's manual, and pull it out with a fuse puller or pair of pliers. Always ensure the replacement fuse matches the exact amp rating.


Production years: 2004, 2005, 2006, 2007, 2008. The 2004 Ford F-150 marked the beginning of the 11th generation of F-150 trucks, which continued through 2008.
