Electrical system Nissan Wingroad is a complex network that controls everything from the headlights to the fuel injection system. In the event of a sudden failure of any node, the first step is to check the status fuses. These small components perform a critical role, breaking the circuit when overloaded and protecting expensive electronics from burning out.
Owners Wingroad Often they are faced with the fact that troubleshooting is delayed due to the lack of clear information about the location of the blocks. In this article, we will analyze in detail where the main and additional fuses are located, how to correctly diagnose and replace them in order to return the car to operation in a matter of minutes.
Design and purpose of fuse blocks
B Nissan Wingroad The protection system is divided into two main circuits, each of which serves certain consumer groups. The first block is located in the engine compartment, directly in the engine compartment. The second unit is located inside the cabin, usually on the driver's side, under the instrument panel.
The motor unit is responsible for high current consumption circuits such as generator, starter, cooling system and fuel pump. These elements consume significant power and therefore require protection with more powerful fuses or power relays. Any problem here could result in the engine being unable to start or overheating.
The cabin unit protects peripheral equipment: audio system, window lifters, interior lighting, cigarette lighter and airbag control units. This is where elements most often burn out due to the connection of non-standard equipment or a short circuit in the wiring.
It is important to understand that each fuse is designed for a strictly defined rated current. The use of an element with an overrated rating is strictly prohibited, as this will lead to melting of the wiring and fire at the first serious overload.
Location and access to blocks in the engine compartment
Access to the main unit under the hood does not require special tools, but does require caution. The block cover is usually fixed with latches and has a schematic representation of the arrangement of elements on the inside. To get started, you must disconnect the negative terminal of the battery to prevent accidental short circuiting.
Open the hood and locate the black plastic box located closest to the battery or firewall. Unclip the cover latches and carefully remove it. Inside you will see rows of fuses of different colors and sizes, as well as large power relays.
Use a flashlight for visual inspection. Transparent cases allow you to immediately assess the condition of the metal jumper inside. If the jumper is torn or the plastic inside is melted, the element must be immediately replacement.
This block often contains fuses responsible for operation. radiator fan and glow plugs (for diesel versions). Checking these items becomes a priority when cooling or cold starting problems occur.
Indoor unit: access and specifics
Cabin fuse box for Nissan Wingroad often hidden behind a decorative panel on the left side of the steering column. To access it, you need to open the side panel cover. Sometimes you need to pull it slightly towards you to release the latches, or unscrew a few screws, depending on the year of the car.
Once the cover is removed you will see a tight arrangement of fuses. There is also a diagram map on which the numbers and purpose of each element are indicated. However, in older models, the diagram may be erased, so having a paper manual or digital copy becomes critical.
In this block, the fuses responsible for alarm, radio tape recorder and heated rear window. If your cigarette lighter stops working, check this particular unit, as it is most often subject to overloads when charging gadgets.
Use special tweezers, which are usually attached to the inside of the block cover, to remove the fuses. It is not recommended to do this with your fingers, as you may accidentally damage adjacent contacts or displace an adjacent element.

Table of main fuses and their purpose
Below is a table describing the most frequently checked items. Please note that numbering may vary slightly depending on the configuration and year of manufacture Nissan Wingroad.
| Designation | Denomination (A) | Purpose | Case color |
|---|---|---|---|
| IGN1 / IGN2 | 15 | Ignition system, ECU | Blue |
| ROOM | 10 | Interior lighting, lock | Red |
| CIG | 15 | Cigarette lighter, socket | Blue |
| HEAD (LH/RH) | 10 | Headlights | Red |
| RADIO | 10 | Audio system, navigation | Red |
Use this table as a guide when troubleshooting. If, for example, it doesn't work wipers, look for the corresponding fuse in the passenger compartment block, it is often designated as WIPER.
Diagnostics and correct replacement
To check the functionality of the fuse, it is not necessary to remove it. Modern multimeters allow you to ring a circuit through contacts located in the case. However, for a 100% guarantee, it is better to remove the element and inspect it visually or check it with a tester in dial mode.
If you find a blown fuse, do not rush to install a new one immediately. First you need to find out the cause of the overload. Might have happened short circuit in the wiring or a powerful consumer exceeding the nominal value is connected.
Replacement is made strictly with an element with the same rating. The color of the fuse body must also match, as it indicates the current strength (red - 10A, blue - 15A, yellow - 20A). This allows you to quickly identify the item without checking the denomination.
It is important to ensure that the new fuse fits snugly in the socket. Poor contact can cause heating and repeated failure, even if the current in the circuit is normal. Never use wire or paper clips to temporarily repair a circuit - this is a recipe for a wiring fire.
☑️ Safe replacement procedure
Common faults and their causes
One of the most common problems is a blown cigarette lighter fuse. Owners Nissan Wingroad DVRs, chargers and compressors are often connected to it. If the total power exceeds 15 Amps, the protection is triggered instantly.
Another common cause is oxidation of the contacts in the fuse box. Due to moisture or condensation, the contacts may lose conductivity, causing false alarms or a complete loss of power to the device. In this case, it is necessary to clean the contacts with alcohol or a special contact cleaner.
- 🔋 Generator may cause voltage surges if the charge regulator is faulty.
- 🔌 Short circuit in the wiring due to rubbing of the insulation on the body.
- 💡 Poor quality lamps with increased power, installed in the headlights.
If after replacing the fuse it blows again within a few seconds, this is a clear sign of a serious problem. In this case, it is dangerous to continue independent experiments; professional wiring diagnostics are required.
Before replacing the fuse, check that the unit itself has not overheated. If the plastic is melted, replacing the element will not solve the problem - you will need to replace the entire unit or repair the connector.
Important nuances and precautions
When working with car electrics, always follow safety rules. Never carry out inspections or replacements with the ignition on, unless required by the instructions. This may cause sparking and shorting.
⚠️ Warning: Never try to repair a blown fuse by wrapping it with foil or wire. This completely eliminates the protection of the circuit, and the slightest overload can cause the car's wiring to catch fire.
It is also worth paying attention to the power relays located next to the fuses. If the relay clicks but the unit does not operate, the problem may be with the relay itself and not with the fuse. In this case, you will need to replace the relay or check its control signal.
For vehicles with a diesel engine, pay special attention to the fuses of the preheating system. During the cold season, the load on them is maximum, and they often fail. Regularly checking their condition will help avoid problems with starting the engine.
What to do if the diagram on the cover is erased?
If the diagram on the block cover is unreadable, use specialized literature or online resources. Enter your vehicle's VIN into a schematic search on the official Nissan forums or specialized databases. Consultation with a service center, where there is access to technical documentation, often helps.
When professional help is needed
If you have checked all the fuses and replaced the burnt ones, but the problem does not go away, then the problem is deeper. This could be a wiring break, a relay malfunction, problems with the control unit or the energy consumers themselves.
In such cases, diagnostics on a bench using professional equipment is necessary. Independent attempts to find a short circuit using the poking method can lead to new damage and increased repair costs.
- 🔧 Complex electronics requires special diagnostic equipment.
- 🌧️ Moisture may cause corrosion of contacts that is not visible to the eye.
- ⚡ Power surges may damage the engine control unit.
Do not delay your visit to service if the problem is systemic. Safety on the road directly depends on the health of the vehicle's electrical systems.
Conclusion
Knowledge of the location and operation of fuses on Nissan Wingroad allows the owner to independently solve up to 80% of minor electrical problems. Regularly checking the condition of the elements and following the operating rules will help avoid serious breakdowns and unplanned expenses.
Remember that electrics are the nervous system of the car. Treat it with respect, use quality parts and do not neglect safety precautions. The correct approach to maintenance guarantees the reliability and durability of your Wingroad.
Where is the interior fuse box located?
The interior unit is usually located to the left of the steering column, behind the decorative panel. To access it, you need to open the side cover, which is secured with latches or screws.
How do you know if a fuse has blown?
A visual inspection of the transparent case will show a break in the metal bridge inside. You can also use the multimeter in dial mode: if the device does not make a sound, the circuit is open.
