How do you read fuse panel 2004 Toyota Sienna?

To read the fuse panel in a 2004 Toyota Sienna, locate the fuse box, typically found under the dashboard on the driver's side or in the engine compartment. The cover of the fuse box usually has a diagram indicating the function of each fuse and its corresponding amperage.

If a fuse is blown, it will typically appear dark or have a broken wire inside; replace it with a fuse of the same amperage.
