This automotive maintenance tutorial was specifically written to assist owners of the second generation (2008, 2009, 2010, 2011, 2012 & 2013) Toyota Highlander in checking or changing a blown fuse or relay in either the engine bay or interior passenger compartment electrical panels.

Owners of other Toyota or Scion vehicles such as the Tacoma, Corolla, Yaris, Prius, Camry, RAV4, Tundra, Sienna, FJ Cruiser, Venza, Avalon, 4Runner, Sequoia, xB, xD, tC, iQ and FR-S may also find these DIY instructions to be helpful.

This 2013 Highlander is equipped with the relatively newer style of low profile mini blade fuses.

Earlier models may have the standard mini blade fuses, which are slightly taller.

Assortment packages of replacement fuses in a variety of amperage ratings (e.g. 5, 10, 15, 20, 25) can be purchased at stores such as Walmart, Pep Boys, Advance Auto Parts, Napa and AutoZone or online at Amazon.

A white plastic fuse puller tool is included on the underside of the engine bay fuse box cover. No additional tools are needed.

The engine bay fuse box is located on the right (driver) side of the engine bay next to the air filter box.

Press in the release tab on the front of the box and pull off the black plastic cover.

There is a white plastic fuse puller tool attached to the underside of the fuse box cover along with a fuse location diagram.

Another fuse location diagram is included in your owner's manual.

There is a small rectangular black plastic electrical relay box located on the far right of the engine bay.

To open the relay box, press in the release tab on the rear edge to disengage the retaining clip before pulling the cover straight off.

Pull the old fuse straight out of the socket.

Replace Fuse Puller Tool
Hold the old fuse up to a light source and examine it.

If the thin metal bar inside the translucent plastic center of the old fuse appears burnt or broken, it is most likely "blown".

If the thin metal strip appears to be intact, the fuse may still be good. But since new fuses are so inexpensive, it should still be replaced as part of your electrical issue troubleshooting process.

Push a new low profile mini blade fuse of the same amperage rating (5, 10, 15, 20, 25, etc) straight in to the socket.

Replace the fuse puller tool on the underside of the engine bay fuse block cover.
