Electrical system of a Japanese car Nissan Wingroad The WFY11 generation is reliable, but with prolonged use or improper use of electronics, problems with blown fuses often arise. Many owners are faced with a situation where the power windows, radio or headlights stop working, and do not know where to start diagnosing.
Troubleshooting in power circuits requires precise knowledge of the location of the mounting blocks and the ratings of the protective elements. In this article we will take a closer look at where the fuse boxes are located on Nissan Wingroad WFY11, how to correctly interpret color coding and what to do if a standard replacement does not solve the problem.
Incorrect selection of a protection element can lead to a short circuit and failure of expensive control units. Therefore, it is important to approach the issue of replacement fuses systematically, using up-to-date information from the manufacturer.
Location of mounting blocks on Nissan Wingroad
On the model Nissan Wingroad WFY11 provides two main installation locations for protective elements. The first block is located in the engine compartment, protecting power circuits such as the cooling fan, generator and fuel pump. The second unit is located inside the cabin, usually under the dashboard on the driver's side.
To access the interior unit, you often need to remove a plastic trim or open the door. Please note that on some copies Nissan access may be limited by the steering column. You will need to carefully release the clips to get a full view of the circuit.
In the engine compartment, the block is closed with a dense black cover that fits tightly to the body. It only needs to be opened with the engine turned off, since under the hood there are elements that are under high voltage when the ignition system is operating.
It's important to know that on some modifications of Wingroad WFY11, the unit in the cabin may have a non-standard location under the glove compartment. If you don't find it under the steering wheel, check the space behind the glove box.

How to properly check and replace a fuse
The replacement process begins with a visual inspection. You will need a special tester or tweezers that comes with the unit. If you do not have professional equipment, you can use a regular multimeter in dial mode.
Before removing the element, make sure that the ignition is turned off. This will prevent accidental short circuiting during removal. The fuse must be removed strictly vertically, without distortion, so as not to damage the contacts in the socket.
If the fuse link inside the transparent body is melted or the wire is broken, the element is considered faulty. Do not try to repair it by soldering or twisting - this will violate the design load and may lead to a fire in the wiring.
☑️ Checking the fuse
Insert a new fuse of the same rating as indicated on the body of the old element. If a new element immediately burns out after installation, it means there is a short circuit or overload in the circuit that requires in-depth diagnostics.
⚠️ Attention: Never use “bugs” made of wire or foil instead of a standard fuse. This is the fastest way to burn out car wiring. Nissan Wingroad at the first overload.
- 🛠 Use only original items or analogues with the exact denomination.
- 🔦 Light the installation site with a flashlight if you are working in the dark.
- 📏 Check the thickness of the insert, as visually similar elements may have different current strengths.
Correctly replacing a fuse is not only about installing a new part, but also about finding the cause of the burnout so that the problem does not recur after an hour of engine operation.
Decoding denominations and color coding
Each fuse is color coded according to its current rating. This is a standard system used in most Japanese cars. Knowing the color palette allows you to quickly identify an element without using tables if the diagram on the cover is erased.
The most common colors on Nissan Wingroad - these are purple (3A), pink (4A), brown (5A), black (7.5A) and red (10A). More powerful elements, such as 20A or 25A, usually have a yellow or white body color.
Sometimes manufacturers use transparent or translucent cases, where the denomination is stamped with numbers. In such cases, the color of the case is not a determining factor, and you only need to focus on the numbers.
Please note that old elements may have faded and discolored the plastic. In this case, you cannot rely on color; you must check the markings on the end or use measuring instruments.
- 🔴 Red - 10A, often used for headlights and brake lights.
- 🟡 Yellow - 20A, protects power windows and heated seat chains.
- 🔵 Blue - 15A, typical for ignition and wiper circuits.
How to find out the exact value without a multimeter?
If the numbers are erased, you can carefully remove the element and attach it to the diagram on the block cover. Matching shape and size often indicates the correct denomination, but this is not a 100% guarantee.
Diagram and description of the main circuits
For accurate diagnosis, you need to know which fuse is responsible for what. The table below shows the main circuits for the model Nissan Wingroad WFY11, which most often raise questions from owners.
| Designation | Denomination (A) | Purpose | Color |
|---|---|---|---|
| ECU-IG | 15 | Engine control unit | Blue |
| GAUGE | 10 | Dashboard and speedometer | Red |
| STOP | 10 | Brake lights and brake sensor | Red |
| WIPER | 20 | Wipers and windshield washer | Yellow |
| POWER | 30 | Window lifters | Green |
Some circuits may have dual purposes or connect multiple devices. For example, the fuse that controls the interior lighting may also power the glove compartment light. When replacing such items, check the operation of all related functions.
You should pay attention to the fuses in the engine compartment. MAIN and ALT. They protect the generator circuit and the main power cable. Their burnout often leads to a complete blackout of the car, even if the battery is working.
⚠️ Warning: If you have a blown fuse rated 30A or higher, it almost always indicates a serious wiring fault or short circuit, rather than a random power surge.
Before replacing fuses in the engine compartment, be sure to let the engine cool to avoid burns from hot parts near the block.
Diagnosis of complex faults
Sometimes replacing the fuse does not work and the problem remains. In this case, it is necessary to check not only the element itself, but also the integrity of the wiring, as well as the operation of the relay. A common cause of problems on Nissan is the oxidation of contacts in connectors.
Use a multimeter to check the voltage at the fuse terminals with the ignition on. If there is voltage on one contact but not on the other, then the problem is in the circuit after the fuse or in the device itself.
It's also worth checking the relays, which are often installed near the fuse box. The relay clicks when the device is turned on indicates that the control circuit is working, but the power circuit may be open due to burnt contacts.
If you find traces of melted plastic around the fuse socket, this is a signal of poor contact or overload. In this case, it is necessary to replace not only the fuse, but also the unit or connector itself to avoid a fire.
What to do if the fuse blows immediately?
Disconnect all devices in the circuit, check the wiring for chafing insulation, and only then try installing a new element.
- 🔌 Inspect the connectors for oxidation or dirt.
- ⚡ Check the relay for burnt contacts.
- 📉 Measure the load resistance to rule out a short circuit.
Frequently asked questions and answers (FAQ)
Where is the replacement fuse box for Wingroad WFY11?
Spare fuses are often located directly in the block under the cover or in a special compartment next to the main block in the cabin. Sometimes they can be found in the armrest or under the driver's floor mat.
Can I use a lower rated fuse?
Technically it is possible, but this will lead to constant burnout under normal load. The fuse must protect the wiring, not the device, so the rating must strictly correspond to the calculated value.
Why do power window fuses blow?
Most often this is due to jamming of the window lift mechanism, wear of the cables, or moisture getting into the control unit. Check the movement of the glass and the operation of the motor.
How to distinguish a relay from a fuse?
Relays are usually cube-shaped and larger in size, and have a contact diagram on the body. The fuses are flat and have a transparent body with a visible insert.
What to do if you don’t have a suitable fuse at hand?
In an emergency, you can use an element with a lower rating to get to the service. But it is impossible to turn on powerful consumers, since the fuse will not withstand the load.
