How to Replace Fuses on Toyota Cars

by Contributing Writer; Updated June 12, 2017

Internal combustion engines run on gasoline, but require the spark of electricity to unleash the power of the fuel. Likewise, all of the electrical components on your car, such as your headlights, turn signals and windshield wipers, are powered by your battery. As with most electrical systems, the primary safety mechanism to prevent overloads on the Toyota car is the simple fuse. These small, easy-to-replace bits of metal and plastic can make the difference between driving in a cool, air conditioned car or sweltering in the heat.

Under The Hood:

 How to Replace Fuses on a Toyota Previa

Turn the ignition switch to the "Off" position. Insure the component with the suspected blown fuse is turned off.

Reach under the central instrument panel cover, located above the air conditioning controls in the center of the dashboard, and press upward on the panel cover release latch. This is where most of the fuses are located in a Toyota Previa. Lift the panel cover up and off.

Observe the underside of the control panel cover. It will have a schematic diagram along with the name of each circuit controlled by the corresponding fuse. Determine the location of the fuse that controls the affected component. The Toyota Previa makes use of three different types of fuses: type A, which are thin and elongated, type B fuses that resemble a box with a window in the top to reveal the fuse link, and type C, which also resemble a box with a clear plastic top.

Grasp the suspected fuse and pull straight up and out. Look down through the clear top of the fuse. If the metal connector is broken and not connected, the fuse is blown. Insert a replacement fuse of the same type and amperage rating into the vacant slot.

Replace the instrument control panel and press down until it snaps closed. Turn the ignition switch to the "On" position. Activate the suspected component. If replacing the fuse did not solve the problem, troubleshoot further or take the car to a qualified technician for repairs.

 How to Replace the Fuses in a Toyota Highlander

Shut down the ignition. Locate the fuse boxes, in the engine compartment on the driver's side.

Find the other fuse box in the passenger compartment on the driver's side to the left side of the instrument panel. Open the fuse box to reveal the fuses inside.

Read the inside cover of the fuse box to learn the location of the fuse you need. Remove the fuse by pulling it out.

See that the inside wire is melted or split if the fuse has blown. Replace it with a new fuse that has the same rating, verifying the correct amperage against the fuse box cover.

Push the new fuse into place and close the fuse box cover. Test out the new fuse once you restart your Highlander.

 How to Replace the Fuses in a Toyota Corolla

Turn the Corolla off. Locate the two fuse boxes; one is in the engine compartment on the driver's side and the other in the passenger compartment on the driver's side to the left of the steering wheel.

Open the fuse box and review the fuse listing on the inside of the cover.

Remove the fuse and inspect the wire in the middle of it. A blown fuse has a broken or melted wire.

Replace the blown fuse with a new one of the same rating. Verify the fuse amp against the cover of the fuse box so as not to replace with the wrong amperage.

Push the new fuse firmly into place and close the fuse box. Verify the fuse is in good working order once you restart your Corolla.

 How to Replace the Fuses in a Toyota Camry

Turn your Camry off before you exchange a blown fuse for a working one. Open the coin tray on the left side of the passenger's side dashboard to locate the fuse box.

Open the fuse box to reveal the fuses. Read the inside of the cover to find the location of the fuse you need to replace.

Remove the fuse using your thumb and index finger. See that the wire inside is burned out and needs replaced.

Push a new fuse of the same rating into place securely. For instance, a 2000 Toyota Camry uses a 10-amp mini fuse for the dash board lights.

Shut the fuse box and check the fuse is working properly once you restart the Camry.

 How to Replace the Fuses in a Toyota Tacoma

Turn your truck off before you work with the fuse boxes. Find one fuse box in the engine area and the other in the passenger's cab on the driver's side under the dash.

Remove the fuse box cover to reveal the fuses. Pay attention to the inside cover because it lists the fuse locations. For example, a 2005 Toyota Tacoma has the cigarette lighter fuse in slot 47 of the engine compartment fuse box.

Pull out the fuse and inspect the inner wire. A blown fuse has a melted or open wire.

Find a new fuse that has the same rating as the one you removed. In Step 2's example, the 2005 Toyota Tacoma uses a 15-amp fuse for its cigarette lighter.

Push the replacement fuse into place and close the fuse box. Make sure the new fuse works once you have started your Tacoma again.

 How to Replace the Fuses in a Toyota Tundra

Turn off your truck before you change out the fuse. Find the two fuse boxes in your Toyota Tundra; one under the hood behind the battery and the other inside the vehicle, under the dash and near the emergency brake.

Open the cover and read the inside list to find the fuse you need to replace. For example, in a 2003 Toyota Tundra the cigarette lighter fuse is under the dash in the slot labeled CIG.

Pull the fuse out and verify the wire inside is melted or broken. Find a new fuse of the same rating. The lighter example in Step 2 would use a 15 amp min fuse.

Push the new fuse into the open slot securely. Close the fuse box.

Restart your Toyota Tundra. Check the fuse and make sure it's working again.
