2023 Nissan Frontier Fuse Box Diagram

Quick answer

Your 2023 Nissan Frontier has three primary fuse box locations:

• Under-hood fuse and relay box: Located in the engine compartment, on the passenger side.
• In-cabin fuse box: Located inside the cabin, under the driver's side dashboard, near the kick panel.
• Cargo/Trunk fuse box: Located in the rear of the vehicle, typically on the driver's side.

Under-hood Fuse and Relay Box

This fuse box contains the higher amperage fuses and relays that control the major systems of your truck. You'll find it on the passenger side of the engine bay, housed in a black plastic box. To access it, release the clips on the lid.

In-cabin Fuse Box

This fuse box is for the various interior circuits and accessories. You'll find it tucked away under the driver's side of the dashboard. It might be necessary to remove a trim panel to gain full access.

Note: Fuse numbers and circuits can vary based on your Frontier's trim level and optional equipment. Always consult the fuse legend printed on the inside of the fuse box lid to verify the correct fuse for the circuit in question.

Cargo/Trunk Fuse Box

For trucks equipped with certain features like a premium sound system or additional power outlets in the bed, there may be a third fuse box in the rear of the vehicle. This is less common but can be found on the driver's side of the cargo area.

How to test a fuse

A blown fuse is a common and relatively easy fix. Here's how to test one:

1. Turn off the ignition.
2. Locate the suspect fuse using the diagrams above and the legend on your fuse box lid.
3. Remove the fuse. You may need a small pair of pliers or a dedicated fuse puller (often found in the fuse box itself).
4. Visually inspect the fuse. Look for a break in the thin metal wire inside the plastic housing. If it's broken, the fuse is blown.
5. Use a multimeter (optional but recommended). Set your multimeter to the continuity setting. Touch the probes to each of the fuse's metal tabs. If the multimeter beeps or shows a reading of 0, the fuse is good. If it remains silent or shows an open circuit, the fuse is blown.
6. Replace the blown fuse with a new one of the exact same amperage rating. Using a higher amperage fuse can cause a fire.

Common blown fuses on this vehicle

• 12V Power Outlet (Cigar Lighter): This is one of the most common blown fuses, often caused by a faulty phone charger or other accessory. If your power outlet stops working, this fuse is the first thing you should check.
• Radio/Infotainment: If your radio or touchscreen suddenly goes dark, the fuse is a likely culprit. This can sometimes happen after jump-starting the vehicle or if there's an internal fault in the head unit.
• Low Beam Headlights: If one of your headlights goes out, it could be the bulb, but it's always a good idea to check the fuse first. If both go out at the same time, it is almost certainly the fuses.
