Fuse Box Diagrams Toyota Sienna (XL20; 2004-2005)

In this article, you will find information about the fuses of the Toyota Sienna (XL20) (models 2004 and 2005), 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 Sienna

If the headlights or other electrical components do not work, check the fuses.

Turn the ignition switch and inoperative component off. Pull the suspected fuse straight out and check it. If the fuse has blown, push a new fuse into the clip. Only install a fuse with the amperage rating designated on the fuse box lid.

If the new fuse immediately blows out, there is a problem with the electrical system. Have your Toyota dealer correct it as soon as possible.
