Vehicle electrical system Nissan Wingroad is a complex network that powers everything from headlights to power windows. When an appliance fails to function, the first cause is often a blown fuse. This is a protective element that opens the circuit during a power surge, preventing wiring fires or failure of expensive components.
Owners Nissan Wingroad (especially right-hand drive models, popular in Russia) are often faced with the need for quick diagnostics. You don’t have to go to the service center right away if the problem is local. Knowing the location of the blocks and the ratings, you can independently restore the functionality of the lighting, music or cigarette lighter in a matter of minutes.
Location of fuse boxes in Nissan Wingroad
By car Nissan Wingroad There are two main places where the protective elements are concentrated. The first unit is located in the passenger compartment, usually behind the instrument panel on the driver's side. The second unit is located in the engine compartment, next to the battery and engine control unit. It is important to understand that different boxes are responsible for different systems.
To access the interior unit, you will need to unscrew several screws or simply unclip the plastic cover latches. Often the lid is attached with latches, which may become stuck over time. Be careful when removing to avoid breaking the fragile plastic of the dashboard. In the engine compartment, the block is protected by a more massive cover, which is also secured with special clamps.
Inside the lid of any of the blocks you will find a sticker with a diagram. However, in some modifications Nissan Wingroad This sticker may be worn off or missing altogether. In such cases, it is necessary to focus on the markings applied directly to the plastic body of the fuse or to the bottom of the seat.
If you are not sure which block is responsible for a particular node, check both. Sometimes engineers distributed the load in a non-standard way depending on the year of manufacture and configuration. For example, in earlier versions Wingroad The ignition circuit could be protected in the cabin, and in later versions it could be moved under the hood.
How to correctly diagnose a burnt out element
Before you go into the unit, make sure that the problem is in the fuse and not in the light bulb or relay itself. Visual inspection is the fastest method. You need to pull out the suspicious element and look at its metal bridge through the transparent plastic.
If the jumper is intact, the fuse is good. If the metal inside is torn or melted, the element must be replaced immediately. Do not attempt to solder the old jumper, this will disrupt the calibration of the protection and may cause a fire. Always use original parts or replacement parts with exactly the same rating.
To remove the fuse, use special tweezers, which are often attached to the block cover or located in the glove compartment. If you don't have tweezers, you can carefully use needle-nose pliers, but be careful not to damage the adjacent contacts. Pressing too hard can move adjacent elements, creating new problems.
⚠️ Attention: Before removing the fuse, be sure to turn off the engine and remove the key from the ignition. Operating under voltage may cause a short circuit even if the element is replaced.
Sometimes the problem is not in the fuse itself, but in poor contact in the seat. Oxidation or corrosion can simulate burnout. Clean the contacts with an eraser or a cotton swab dipped in alcohol before installing a new element.
- ✅ Always have a set of spare fuses of different ratings in your glove compartment.
- ✅ Use a multimeter to accurately check the circuit during visual inspection.
- ✅ Do not replace the fuse with a more powerful one if it constantly blows.
Diagram and ratings of main fuses
Each fuse in Nissan Wingroad has its own color and rating, indicating the maximum current in Amperes. Pink ones are usually 30A, blue ones are 15A, yellow ones are 20A. Color coding helps you quickly identify an element, even without a diagram. However, you should not rely only on color; it is better to check the markings.
Below is a table with the most frequently blown fuses and their purpose for typical configurations Nissan Wingroad (engine 1.5/1.8):
| Designation | Denomination (A) | Purpose | Location |
|---|---|---|---|
| 10 (IG1) | 10 | Ignition system, ECU | Salon |
| 30 (CIG) | 15 | Cigarette lighter, socket | Salon |
| 45 (HEAD) | 10 | Low beam headlights | Engine compartment |
| 55 (WIPER) | 20 | Windshield wipers | Salon |
| 60 (RADIO) | 10 | Audio system | Salon |
Note that high-draw circuits such as the radiator fan or power window motors are often protected by relays, not just fuses. If the fuse is intact, but the motor does not work, check the relay in the block. The relay can be replaced in place of a known-good analogue (for example, a fan) for testing.
If your climate control is not working, check the circuit AC COMP under the hood. It often burns out when the compressor clutch jams.
For an accurate diagnosis, use wiring diagram your specific year of manufacture. Engineers could change the pinout even within the same model year. Find your car's VIN and order the specification from the dealer or online to avoid mistakes.

Step-by-step replacement instructions
The replacement process is extremely simple, but requires care and adherence to the sequence of actions. First, find the faulty element using the methods described above. Then prepare a new fuse of the same rating. Never use wire or a paper clip in place of a fuse.
You will need the following set of tools: a set of screwdrivers, tweezers (ideally from the car kit) and a multimeter. If you are working in the dark, have a flashlight ready. The lighting must be good to see small parts on the fuse body.
☑️ Preparing to replace the fuse
Remove the unit cover by releasing the latches. Carefully remove the blown fuse with tweezers. Insert the new element as far as it will go. It should fit tightly, without play. If the contact is loose, bend the fuse legs with pliers.
After installation, turn on the ignition and check the operation of the device. If the fuse blows again immediately after replacement, there is a short circuit in the circuit. In this case, further independent actions are dangerous and a visit to an auto electrician is required.
⚠️ Attention: If the new fuse blows instantly, do not try to replace it with a more powerful one. This is a direct path to a wiring fire in the cabin or under the hood.
Sometimes it happens that the fuse is visually intact, but the circuit does not work. In this case, use the multimeter in dial mode. Place the probes on the metal legs of the element. If the device beeps or shows zero resistance, the fuse is good.
Replace the unit cover and secure the fasteners. Make sure the lid fits tightly and does not loosen. Vibration can cause contacts to oxidize or the fuse to blow out while driving. Make sure all tools are removed from the engine compartment.
Correctly replacing a fuse is not just inserting a new element, but checking the reasons for its blown and the condition of the contacts in the socket.
Frequent malfunctions and their causes
Owners Nissan Wingroad Often encounter a blown cigarette lighter fuse. The main reason is connecting powerful car chargers or inverters that exceed the permissible current. The culprit may also be a short circuit in the charging cord of the gadget itself.
Another common problem is failure of the front power windows. In winter, the mechanism may freeze, creating a peak load on the motor. As a result, protection is triggered. If you hear a characteristic click of the relay, but the motor does not turn, check the fuse and the condition of the mechanism.
Headlight malfunction may be due to oxidation of the contacts in the lamp socket. High transient resistive heating causes the fuse to blow. Replace oxidized contacts or the entire cartridge to prevent the problem from recurring.
- ❌ Do not connect more than 150 W load to the cigarette lighter.
- ❌ Avoid using cheap Chinese chargers.
- ❌ Do not turn on heated seats and windshield wipers at the same time when the engine is cold.
Sometimes the problem lies in the fuse box itself. The plastic base can warp over time due to heat, resulting in poor contact. In such cases, cleaning the contacts or replacing the entire unit if the damage is critical helps.
Why do fuses blow in Nissan Wingroad?
A common cause is old wiring, the insulation of which deteriorates over time. This is especially true for right-hand drive cars imported from Japan, where the climate is more humid and salty. The quality of assembly of the harnesses at the Nissan plant in the 90s and 2000s also affects.
Prevention and maintenance of electrical circuits
To avoid sudden failures, carry out regular maintenance. Inspect the fuse box every six months for signs of moisture or oxidation. If you find a white coating, clean it with a special contact fluid.
Check the condition of the wires going to powerful consumers. The insulation must not have cracks or traces of melting. If defects are found, replace the wiring section or use heat shrink tubing to restore the insulation.
Do not overload the on-board network with additional equipment. If you are installing a powerful audio system or additional lights, run separate power lines with their own fuses. Do not connect them to standard circuits without calculating the load.
In winter, pay special attention to the operation of the windows and locks. Ice can block the mechanism, causing overload. If you hear the sound of the engine running, but the mechanism does not move, immediately turn off the ignition.
Before winter sets in, treat all electrical connectors and contacts with silicone grease. This will prevent oxidation and moisture from entering the contacts.
Use only high-quality fuses from well-known brands. Cheap analogs may have an unstable response threshold, which is dangerous for electronics. Original parts Nissan or proven substitutes (e.g. Bosch or Denso) guarantee reliable protection.
Keep the fuse diagram in the glove compartment. If you have lost the original sticker, print a diagram from the Internet or draw one yourself. This will save you time and nerves in case of a breakdown away from home.
When you need specialist help
If you replace a fuse and it blows again after a couple of seconds, the problem is deeper. This could be a short circuit in the wiring harness or a malfunction of the unit itself (generator, starter, ECU). In such cases, independent repairs can lead to even greater damage.
Contact a professional if the problem concerns the engine management or safety systems (ABS, airbags). These systems require complex diagnostics with a scanner. An error in them can lead to brake failure or the inability to start the engine.
If you smell something burning or see sparks in the fuse box, stop working immediately. This is a sign of a critical short circuit. Call a tow truck or electrician to the site to avoid a fire.
⚠️ Attention: If after replacing the fuse you hear strange sounds from the unit (crackling, hissing), immediately disconnect the battery. This is a sure sign of a serious short inside the switchboard.
Do not try to “fix” burnt tracks on the fuse block board if you do not have experience in radio installation. This is a temporary solution that can lead to unstable operation of the entire electrical system. It is better to replace the entire unit or take it to a specialized workshop.
FAQ: Frequently asked questions
Where is the fuse box located in a 1998 Nissan Wingroad?
On 1998 models, the main unit is located in the engine compartment to the left of the battery, and the secondary unit is located in the passenger compartment under the instrument panel on the driver's side. To access the interior unit, you need to unscrew the panel mounting screws.
Can I use a higher rated fuse?
No, it is strictly prohibited. The fuse is designed to protect a specific wiring. Installing a more powerful element will cause the wiring to overheat and melt before the protection operates, which can cause a fire.
What should I do if the cigarette lighter fuse keeps blowing?
First, check to see if the device connected to the cigarette lighter is too powerful. If the load is normal, check the wiring for shorts. The charger plug or the wiring inside the cigarette lighter may be damaged.
How to check a fuse without a multimeter?
Visually inspect the transparent housing. If the metal bridge inside is torn or melted, the fuse is faulty. You can also gently tug it with tweezers - if it sits very loosely or dangles, contact may be broken.
Why do fuses blow in the engine compartment?
Fuses in the engine compartment often blow due to exposure to moisture, salt and high temperatures. Oxidation of contacts or damage to wiring insulation in an aggressive environment under the hood are the main causes of such failures.
