Quick Answer
The 2018 Toyota Camry features three main fuse box locations: under the hood (engine compartment), inside the cabin (driver's kick panel), and in the trunk (cargo area).
Under-Hood Fuse Box (Engine Compartment)
This fuse box, located in the engine bay near the battery, primarily houses fuses and relays for critical engine functions, lights, and other high-current components. Always consult the lid of your fuse box for the exact layout, as configurations can vary slightly by trim level.

Interior Fuse Box (Driver's Kick Panel)
Located behind a cover on the driver's side kick panel, this fuse box handles power for many convenience features, interior electronics, and accessories. Always check your owner's manual or the fuse box lid for the most accurate information.

Trunk/Cargo Area Fuse Box
The 2018 Toyota Camry also has a fuse box located in the trunk area, often behind a removable panel on one of the side trim pieces. This fuse box typically controls power for components in the rear of the vehicle, such as trailer connections (if equipped), rear power outlets, and other specific trunk-related functions. For exact details, refer to the diagram on the fuse box cover.

How to Test a Fuse
- Locate the Fuse Box: Identify the fuse box related to the faulty component.
- Identify the Suspect Fuse: Consult the fuse diagram on the fuse box lid or in your owner's manual to find the fuse for the circuit you're troubleshooting.
- Inspect Visually: A blown fuse will often have a broken wire inside. This is usually visible through the clear plastic body of the fuse. Look for a gap in the metal strip.
- Use a Fuse Tester or Multimeter: For a more accurate test, use a fuse tester. Touch the probes to the small metal test points on the top of the fuse. If the tester lights up (or shows continuity on a multimeter), the fuse is good. If not, the fuse is blown.
- Replace with Correct Amperage: If the fuse is blown, replace it with a new fuse of the exact same amperage (A) and type. Never use a fuse with a higher amperage, as this can cause severe electrical damage or fire.
Common Blown Fuses on This Vehicle
While fuses can blow for various reasons, some common culprits on the 2018 Toyota Camry include:
- Cigar Lighter / 12V Outlets (CIGAR, PWR OUTLET): Often blow due to incompatible or faulty accessories being plugged in, or drawing too much power.
- Radio / Infotainment (RADIO, RADIO NO. 2): Can blow if aftermarket equipment is installed incorrectly or if there's a short circuit in the system.
- Headlights (H-LP LH, H-LP RH, H-LP LL, H-LP RL): Can blow due to a faulty bulb, a short in the wiring, or sometimes just an aged fuse.
- Brake Lights (STOP): Often blow when a brake light bulb fails or has an intermittent short.
- Blower Motor (BLOWER MOTOR): Can blow if the blower motor is failing and drawing excessive current, or if there's an obstruction causing it to work harder.
What to check first: If you have a blown fuse, first identify what component stopped working. Disconnect any accessories from power outlets. Check the wiring for any obvious signs of damage or pinching. If the fuse blows immediately after replacement, there's likely a short circuit in the component or wiring that needs professional diagnosis.

Before you pull a fuse on the 2018 Toyota Camry
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
