Fuse box in Nissan Navara - This is a critical component on which the operation of all electrical equipment of a pickup truck depends. A blown fuse can leave you without headlights, windshield wipers or even an immobilizer, and an incorrect replacement can cause a short circuit. In this article we will look at where to look for fuse blocks on Navara D40 (2005–2014) and NP300 (2015–present), how to decipher their circuits, and what to do if the fuse blows over and over again.
Feature Nissan Navara — the presence of several blocks at once: the main one in the cabin, an additional one under the hood, and even separate fuse links in high-load circuits (for example, for electric power steering or cooling fan). We have collected current diagrams with ratings, typical causes of failure and step-by-step instructions for replacement - taking into account nuances that are not written about in the official manual.
Where is the fuse box located on Nissan Navara?
Depending on generation and configuration Navara may have up to three fuse blocks:
- 📍 Main cabin block — located under the instrument panel on the driver's side. On D40 it is hidden by a plastic cover with latches, on NP300 - behind the decorative panel to the left of the steering column.
- 🚗 Additional block under the hood - usually next to the battery or on the left mudguard. High power fuses are located here (e.g. for
starterorgenerator). - ⚡ Fuse links - can be hidden in wiring harnesses (for example, near the relay box or in the engine compartment). They are often confused with relays, but they perform the same function as fuses.
On Navara D40 In pre-restyling versions (2005–2008), the cabin unit can be moved closer to the central tunnel, and in restyled versions (2009–2014) it can be moved under the glove compartment. B NP300 (2015+) blocks are unified with other models Nissan (For example, Pathfinder), but their location depends on the supply market (European and Asian versions are different).

Fuse diagram and decoding Nissan Navara D40
Below is the current diagram for Navara D40 with diesel (YD25DDTi) and gasoline (VQ40DE) engines. Please note: fuse ratings may vary depending on equipment (e.g. versions with climate control or xenon headlights).
| Fuse no. | Denomination (A) | What is he responsible for? | Notes |
|---|---|---|---|
| F1 | 10 | Engine control unit (ECU), immobilizer |
If it burns out, the engine will not start |
| F10 | 15 | Audio system, navigation | Often burns out during a short circuit in the speakers |
| F20 | 20 | Windshield wipers, washer | Check the washer motor if it burns out frequently |
| F30 | 30 | Electric power steering (EPS) |
When burned, the steering wheel becomes heavy |
| F40 | 40 | Radiator cooling fan | Blowing this fuse will cause the engine to overheat! |
A complete diagram for your modification can be found on the back of the fuse box cover or in Operating manual (section Fuses and Fusible Links). If there is no diagram, use a multimeter in dial mode to determine the purpose of each fuse.
⚠️ Attention: On Navara D40 with the system 4WD There is a separate fuse in the block under the hood for 100A for the transfer case. Replacing it requires disconnecting the battery!
Typical faults and causes of blown fuses
If a fuse blows immediately after replacement, this is a signal of a serious problem in the electrical circuit. Here are the most common reasons for Nissan Navara:
- ⚡ Short circuit (SC) - the most common reason. Most often it occurs in wiring harnesses under the hood (due to chafing of insulation) or in doorways (due to broken wires).
- 💡 Circuit overload — for example, when installing powerful LED lamps in headlights or connecting additional equipment (winches, refrigerators) without a relay.
- 🔋 Consumer fault - burnt out heater motor, jammed fan or faulty
ECUmay cause current surges. - 🌧️ Contact corrosion - oxidation in the fuse box or at the battery terminals leads to increased resistance and overheating.
Particular attention should be paid to fuses F30 (EPS) And F40 (fan). The first one often burns out due to moisture getting into the power steering control unit (a typical problem for Navara D40 after 100 thousand km). The second is due to a jammed fan or a malfunction of the temperature sensor.
How to check a circuit for a short circuit?
1. Disconnect the battery. 2. Remove the fuse for the problematic circuit. 3. Connect the multimeter in dial mode to the contacts of the fuse socket. 4. If the device shows “0 Ohm”, there is a short circuit in the circuit. 5. Turn off consumers one by one (for example, headlights, motors) to find the problem area.
Step-by-step instructions for replacing the fuse
Replacing the fuse with Nissan Navara It seems like a simple operation, but there are nuances that will help you avoid mistakes:
- Turn off the ignition and remove the key from the lock. On NP300 with the system
Intelligent Keyjust press a buttonLOCKon the keychain. - Find the faulty fuse. Use a diagram or visually check the filament (a blown fuse will have a break or a blackened body).
- Remove the fuse special tweezers (usually attached to the block cover). Do not use metal tools - they can damage the contacts!
- Install a new fuse same denomination. Increasing amperage (for example, with
10Aon15A) will result in a risk of fire. - Check circuit operation. If the fuse blows again, do not install a new one until you find the cause (see section above).

Check the rating of the new fuse (must match the old one)|
Inspect the nest for oxidation or foreign objects|

⚠️ Attention: On Navara NP300 with the system ProPILOT replacing fusesF1(control unit) orF50(radars) may require system recalibration in the service!
How to check a fuse without a multimeter?
If you don’t have a tester at hand, there are three ways to check the fuse by eye:
- 🔍 Visual inspection - a burnt-out thread inside the fuse will be torn or blackened. However, some fuses (especially miniature ones) may appear intact even if they are faulty.
- 🔄 Replacement method - Install a known-good fuse of the same rating. If the circuit worked, the old fuse was blown.
- 💡 Checking for spark — carefully close the contacts of the fuse socket with a screwdriver (for a short time!). If the circuit is good, you will see a spark or hear the relay click. Dangerous for high current circuits (eg starter)!
For accurate diagnostics, it is better to use a multimeter in continuity or resistance testing mode. Connect the probes to the terminals of the fuse: if the resistance approaches zero, the fuse is good, if it approaches infinity, it is burned out.
If a fuse blows when you turn on a particular appliance (such as headlights), check its current draw. To do this, connect a multimeter in series in current measurement mode (up to 10A) between the fuse and the socket. If the current exceeds the fuse rating by more than 20%, look for a fault in the device.
Frequently asked questions about fuse blocks Nissan Navara
Is it possible to install a larger fuse if it keeps blowing?
No! Increasing the fuse rating can lead to overheating of the wiring and even a fire. If the fuse blows repeatedly, there is a short circuit or overload in the circuit. It is necessary to find and eliminate the cause, and not mask it with a “more powerful” fuse.
Where can I find a fuse diagram for Nissan Navara NP300 2020?
The diagram should be on the back of the fuse box cover. If it is not there, download it Electrical Wiring Diagram for your model on the website Nissan TechInfo (registration required) or use online spare parts catalogs (e.g. Nissan Parts Europe). For NP300 diagrams with designation are relevant D23.
Why after replacing the fuse F30 (EPS) does the steering remain heavy?
This may mean that not only the fuse has burned out, but also the electric power steering control unit itself (EPS Control Unit). Check the voltage at the unit connector (should be 12V on contact +B). If there is voltage, but the steering wheel does not work, diagnostics with a scanner is required (for example, Launch X431) for errors C1130 or C1131.
How to protect the fuse box from moisture?
On Navara D40 The block under the hood often suffers from water ingress (for example, when washing or in the rain). To protect it:
- Apply dielectric grease (For example, CRC 2-26) to contacts.
- Install additional rubber cover per block
- Check integrity drainage holes in the engine compartment - they should not be clogged with dirt.
