2016 Nissan Frontier: Fuse Box Diagram & Amperage

Quick Answer

On the 2016 Nissan Frontier, you will find three primary fuse box locations:

• Under-Hood (IPDM E/R): Located in the engine bay, on the passenger side, near the battery. This box contains higher-amperage fuses and relays for major systems.
• In-Cabin (Junction Block): Located inside the passenger compartment, behind a trim panel on the passenger side kick panel. This box services most of the interior and convenience-related circuits.
• In-Dash (Fuse Block): Located to the left of the steering column, behind a small storage compartment. This is a smaller, more accessible fuse block for frequently used circuits.

Under-Hood Fuse & Relay Box (IPDM E/R)

This is the main fuse box on the 2016 Frontier, located on the passenger side of the engine compartment. You'll need to remove the cover to access the fuses and relays. Always check the diagram on the underside of the cover to confirm fuse locations, as they can vary slightly based on your truck's trim level and options.

Relay Locations (Under-Hood)

• ECM/PCM Relay: Controls power to the engine computer.
• Fuel Pump Relay: Activates the fuel pump when the ignition is turned on.
• Starter Relay: Engages the starter motor.
• A/C Relay: Engages the A/C compressor clutch.
• Headlamp Relay: Switches power for the high and low beams.
• Trailer Tow Relay: Manages power distribution to the trailer tow connector.

In-Cabin Fuse Box (Junction Block)

This fuse box is located behind the glove compartment. You will need to open the glove compartment, press in the sides to release the stops, and let it swing down completely to access the fuse panel.

How to Test a Fuse

A blown fuse is a common and usually easy-to-fix problem. Here's how to check if a fuse is bad:

1. Turn off the vehicle and remove the key from the ignition.
2. Locate the correct fuse box and remove the cover.
3. Identify the suspect fuse. The diagram on the fuse box cover should help you find the right one.
4. Remove the fuse. A small fuse puller tool is often included in the fuse box, or you can use a pair of needle-nose pliers.
5. Inspect the fuse. Look at the thin metal strip inside the plastic housing. If the strip is broken or melted, the fuse is blown and needs to be replaced.
6. Replace with a new fuse of the same amperage. Using a fuse with a higher amp rating can cause serious damage to the electrical system.

Common Blown Fuses on the 2016 Nissan Frontier

• Cigar Lighter / 12V Power Outlet: These fuses often blow when a faulty or high-draw device is plugged in. If the fuse is blown, check the device you were using for any visible damage before replacing the fuse.
• Radio / Audio: If your radio suddenly stops working, the fuse is the first thing to check. This can sometimes happen due to a voltage spike.
• Tail Lights / Brake Lights: If you have a tail light or brake light out, check the bulb first. If the bulb is good, the fuse is the next likely culprit.
• Blower Motor: If your interior fan stops working on all speeds, the blower motor fuse may have blown. If it only works on high, the blower motor resistor may be the issue.

Note: This information is based on the most common configurations for the 2016 Nissan Frontier. Always verify fuse locations and ratings with the diagram printed on your vehicle's fuse box cover.

If you've checked the fuses and are still having electrical problems, it may be time to consult a professional. Find a trusted shop on Repairius for expert diagnosis and repair.
