In this article, you will find information about the fuses of the Toyota Tundra (XK50) (models 2007, 2008, and 2009), including diagrams of the fuse boxes, a list of fuses, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Toyota Tundra
The fuses are designed to blow, protecting the wiring harness from damage. If any of the electrical components do not operate, a fuse may have blown. If this happens, check and replace the fuses as necessary. Replace the blown fuse with a new fuse of an appropriate amperage rating. The amperage rating can be found on the fuse box lid.
If the replaced fuse blows again, have the vehicle inspected by your Toyota dealer.
Caution!
- Never use a fuse of a higher amperage rating than indicated, or use any other object in place of a fuse.
- Always use a genuine Toyota fuse or equivalent. Never replace a fuse with a wire, even as a temporary fix. This can cause extensive damage or even fire.
- Do not modify the fuse or the fuse box.
Location of Fuse Boxes

Push the tab in and lift the lid off.
