Vehicle electrical system Nissan Wingroad the second generation (Y12 body) is built according to a classic scheme for the Japanese automobile industry, where each unit is protected by a separate element. When the power window stops working, the heater fan does not turn on, or the dashboard lights go out, the driver needs to quickly find the cause of the problem. Most often, the problem lies in the burnout of the fuse link, which breaks the circuit during a power surge, saving expensive wiring and electronic control units.
For successful repairs to the owner Nissan Wingroad 11 It is important to understand not only the location of the blocks, but also the logic of their markings. Unlike their European counterparts, Japanese manufacturers often use specific designations, where numbers indicate the current strength and letters indicate the purpose of the circuit. Explanation of fuses requires a careful approach, since incorrectly replacing an element with a more powerful one can lead to a fire in the wiring.
In this article we will analyze in detail the location of the blocks, provide a table describing each element and give recommendations for self-diagnosis. You will learn how to distinguish a blown fuse visually and using a multimeter, as well as what nuances exist when replacing a relay in the passenger compartment unit. Knowing this information will save you time and money in the service.
Location of fuse boxes and their features
By car Nissan Wingroad The second generation provides two main installation locations for protective elements: the engine compartment and the interior. The block in the engine compartment is responsible for powering powerful consumers such as the generator, starter, cooling fan and engine control units. It is located in a black plastic case, which is located to the right of the battery, closer to the mudguard.
The second unit, responsible for cabin equipment and auxiliary systems, is located inside the cabin. To access it, you need to open the driver's door and remove the side dashboard cover. Usually it is attached to plastic latches and unscrewed with one screw. This block contains fuses that protect the power windows, radio, cigarette lighter and alarm. Correct diagnosis begins with determining which unit is responsible for the non-working device.
It is important to note that the engine compartment also contains powerful relays and large fuse links (maxspeeds), rated for currents in excess of 30 A. These elements are rectangular in shape and are often painted black or gray. When checking their integrity, a visual inspection may not be sufficient, since the internal spiral may not be completely damaged, but the contact will be broken.
- 🔍 The block in the engine compartment is protected from moisture and dust by a thick cover with a rubber seal.
- 🔧 Access to the interior unit is carried out without the use of tools, just pull the lid protrusion.
- 🚗 In the covers of both blocks there is usually a diagram indicating the denominations, but over time it can be erased.
Detailed explanation of the elements of the block under the hood
Block under the hood Nissan Wingroad Contains elements critical to the operation of the engine and charging system. High rated fuses (from 40 A to 100 A) are located here, which protect the circuits from short circuits. The main consumers protected by this unit are the ignition system, fuel pump, engine control system (ECU) and generator.
Particular attention should be paid to the fuse MAIN (or BAT) which is responsible for supplying power to the entire vehicle through the ignition relay. If this element burns out, the car will be completely de-energized, and even the alarm may not work. This block also contains elements responsible for the operation of the air conditioner and cooling system, which often experience peak loads when turned on.
When deciphering the markings on the body under the hood, you can come across symbols that are not always intuitive. For example, the abbreviation FAN may refer to either the radiator fan or the heater, depending on location. To accurately determine the purpose of the element, it is necessary to check the factory diagram, since in different configurations Wingroad 11 load distribution may vary.

Fuse box in the cabin: purpose and verification
Salon block Nissan Wingroad most often visited by the driver, as there are elements responsible for comfort here. This includes fuses for the cigarette lighter, audio system, power windows and central locking. It is the burnout of one of these elements that most often becomes the reason for calling the service for minor repairs. Fault localization in this unit it usually happens quickly due to the accessibility of the lid.
When checking the interior elements, pay attention to the color coding. Yellow fuses are usually rated at 20 A, red fuses at 10 A, and blue fuses at 15 A. However, you should not rely only on color, since during operation the plastic may fade or be replaced with an analogue of a different color. Always check the number printed on the top of the case.
Particular attention should be paid to the cigarette lighter fuse, as it often blows due to the connection of powerful chargers or heaters. The cigarette lighter circuit may also contain a relay that is responsible for supplying voltage to the outlet. If the fuse is intact but the outlet is not working, the problem may be with the relay itself or with the wiring.
- 🔌 Fuse CIG (cigarette lighter) is usually rated 15A or 20A.
- 🎵 Element RADIO protects the audio system and navigator from power surges.
- 🔓 DOOR is responsible for the operation of the central locking and power windows.

Table of main denominations and explanation
To make troubleshooting easier, we have prepared a summary table of the main elements found in the blocks Nissan Wingroad 11. This information will help you quickly determine which fuse is responsible for a specific vehicle component. Please remember that this table is a general guide and there may be slight differences in your specific vehicle depending on the year of manufacture and equipment.
| Designation | Denomination (A) | Purpose | Location |
|---|---|---|---|
| IGN | 10-15 | Ignition system, engine ECU | Salon / Under the hood |
| ECU | 7.5-10 | Engine control unit (ECU) | Salon |
| WIPER | 15-20 | Windshield wipers (windshield wipers) | Salon |
| HEATER | 20-30 | Heater fan (stove) | Salon |
| ALT | 60-100 | Generator, charging circuit | Under the hood |
When working with a table, it is important to note that the symbols may vary. For example, instead of WIPER may occur WIP, and instead HEATER — HTR. Also, some versions may have a separate fuse for heated seats, if the car is equipped with them. Accurate identification requires verification with the markings on the block cover itself.
⚠️ Attention! Never replace a blown fuse with a higher rated one. This will lead to overheating of the wiring and possible fire, as the circuit protection will be compromised.
Diagnostic tools and element replacement
You don't always need a multimeter to check the integrity of fuses, although it is the most accurate tool. In most cases, a visual inspection through the transparent element body is sufficient. If the metal bridge inside is melted or torn off, the fuse has blown. However, for hidden defects or checking relays, it is better to use a tester.
How to check a fuse with a multimeter?
Switch the multimeter to continuity mode (diode or sound wave icon). Apply test leads to the two metal contacts on top of the fuse. If the meter makes a sound or shows zero, the fuse is good. If it shows infinity or does not make a sound, the element has burned out.-->
The replacement process is extremely simple
remove the faulty element using a special clip, which is usually attached to the block cover, and insert a new one of the same rating. It is important to make sure that the new fuse fits tightly into the seat and does not loosen. Quality of contact directly affects the reliability of the power grid.
If the fuse burns out immediately after replacement, this indicates a short circuit in the circuit. In this case, further operation of the vehicle is prohibited until the cause of the short circuit is identified. Check the wiring for chafing, insulation, and connected additional devices such as alarms or parking sensors.
- 🛠 Use the plastic tweezers included in the removal kit to avoid damaging the contacts.
- 🔦 Turn on the flashlight to better see the insides of the transparent fuse housing.
- 📏 Always check the value of a new element before installation.
Relay features and diagnosis of complex faults
In addition to fuse links, in blocks Nissan Wingroad 11 There are many relays installed that control the power supply to powerful consumers. A relay is an electromagnetic switch that can fail even if the fuse is working. Frequent symptoms of a relay malfunction are the absence of clicks when the device is turned on or its chaotic operation.
Relays often have markings on their housing indicating their function, e.g. FAN RELAY or MAIN RELAY. If you suspect a relay malfunction, try gently tapping it or temporarily replacing it with a similar one from another circuit (if it matches the contacts and rating). This will allow you to quickly localize the problem.
Complex faults, such as intermittent power outages or false alarms, can be associated with oxidation of contacts in the fuse box itself. Over time, contacts can oxidize from moisture or overheating, which leads to increased contact resistance and heating. Cleaning contacts and treating them with a special spray often solves the problem without replacing the elements.
⚠️ Attention! When replacing a relay, make sure it is installed in the correct direction. Incorrect installation can lead to short circuits of contacts inside the unit and failure of the electronics.
Prevention and operating tips
To avoid frequent blown fuses, you should follow simple rules for operating the vehicle's electrical network. Do not connect devices that consume current exceeding the permissible limit (usually 10-15 A) to the cigarette lighter and sockets. Using high-power inverters or heaters without a fuse can lead to catastrophic consequences.
Inspect the fuse box regularly for moisture or dirt. If the block cover under the hood is damaged or the sealing rubber is dry, water can get inside and cause corrosion of the contacts. In this case, it is necessary to replace the seal or the cover itself.
Keep a spare set of fuses in the glove compartment. There are universal sets on sale with different denominations that take up minimal space but can save the situation on the road. Availability of stock will allow you to quickly fix the problem and continue on your way without wasting time searching for an auto parts store.
- 🚫 Avoid using homemade jumpers instead of fuses.
- 🔋 Monitor the condition of the battery terminals, as poor contact causes voltage surges.
- 📝 Keep a log of replacements if fuses blow regularly - this will help you find a systemic problem.
Regular checking of the fuse box and cleanliness of contacts is the key to stable operation of Nissan Wingroad electrics.
