Owners of a compact crossover Nissan Juke Models of 2014 are often faced with the need to check the electrical circuit when certain vehicle components fail. Whether it's a blown headlight bulb, a faulty power window, or a malfunctioning cigarette lighter, the root cause in most cases is a blown fuse. This seemingly insignificant part plays a critical role in protecting expensive electronics from short circuits and overloads.
Electrical diagram Nissan Juke this model year is quite complex and is divided into several zones, which can confuse an inexperienced driver. To effectively troubleshoot a fault, you need to clearly understand where the fuse boxes are located, how to correctly identify them, and what tools are needed for diagnosis. In this article we will analyze in detail all aspects of working with the electrical system of your car.
Main components and location of protection units
Power supply system Nissan Juke 2014 is divided into two main blocks, each of which is responsible for its own consumer groups. The first of them is located directly inside the car, while the second is located in the engine compartment. Understanding this dichotomy is key to rapid diagnosis.
The interior fuse box is hidden behind a decorative plastic panel located on the driver's side of the dashboard. To access it, only a small force is required to unlatch the lid latches. Inside you will find not only fuse links, but also relays that control various comfort and safety systems.
The second unit, located under the hood, is responsible for powering highly loaded components such as the generator, starter, cooling fan and fuel injection system. This unit is protected from moisture and dirt, but care should be taken when inspecting it, especially if the engine is still hot.
- 📍 Interior unit: located to the left of the steering column, behind the removable panel.
- 🔧 Engine compartment: located on the right side of the engine compartment, in a black plastic case.
- 🔑 Tool: Tweezers for removing fuses are usually attached inside the interior block cover.
⚠️ Attention: Before starting any work on the vehicle's electrical system, be sure to ensure that the ignition is completely turned off and the keys are out of the ignition.
Each block has its own unique marking and arrangement of elements. Never attempt to remove a fuse without first consulting the appropriate table to avoid accidentally removing an element responsible for another function.
It is important to note that in some modifications Nissan Juke There may be additional relay blocks responsible for the operation of the air conditioning system or premium audio system. Their location may differ slightly from the standard layout, so always check the instructions specifically for your configuration.
During a visual inspection, pay attention to the condition of the fuse box. Any signs of melting, blackening or cracking indicate that there is a serious failure in the circuit, and simply replacing the part may not solve the problem unless the root cause is addressed.
How to properly diagnose and replace a fuse
The process of replacing a blown fuse seems simple, but requires following a certain sequence of actions to avoid errors. The first step is to localize the faulty element, which is impossible without understanding the principle of operation of the fuse link.
After opening the fuse box, you will need to remove the cover and carefully inspect each element. Most modern fuses have a case made of transparent plastic, which allows you to visually assess the condition of the metal jumper inside.
If the jumper is intact, this does not always guarantee serviceability, so it is recommended to use a multimeter to test the continuity of the circuit. However, in the field, the “rearrangement” method is often used: a working fuse from an unloaded circuit is placed in the place of a suspicious one in order to check the operation of the unit.
- 🔍 Visual inspection: look for a broken metal thread or blackening inside the case.
- 🛠️ Replacement: use a fuse of strictly the same ampere load as the burnt one.
- 🚫 Prohibition: never use paper clips or pieces of wire as a substitute.
⚠️ Attention: Installing a fuse with a higher current rating is strictly prohibited, as this can lead to a fire in the wiring and failure of the electronic control units.
To remove the part, use special plastic tweezers, which often come with the block cover. If you don’t have tweezers, you can use small pliers with insulated handles, but this must be done very carefully so as not to damage adjacent elements.
After removing the old fuse and installing a new one, do not rush to immediately close the cover. Turn on the ignition and check the operation of the unit that has stopped functioning. If the problem is solved, you can close the unit and continue your trip.
If a new fuse blows immediately after installation, this is a clear sign of a short circuit. In this case, further operation of the car is impossible, and you must contact a specialized service to find the location of the short circuit.

Explanation of circuit diagram and fuse ratings
Every fuse in the block Nissan Juke has its own denomination, indicated by numbers on the case, and corresponds to a specific function. Understanding this marking will allow you to quickly find the item you need without spending a lot of time searching through the instructions.
The current rating is indicated in amperes (A) and can vary from 5A to 30A and higher. The color of the case also often corresponds to the current strength: orange - 5A, red - 10A, blue - 15A, yellow - 20A, and so on. This color coding helps to quickly identify the desired item.
The fuse location diagram is usually pasted on the inside of the block cover. If the sticker is missing or erased, you need to refer to the technical documentation for the car or find a decoding on the Internet using the VIN code.
| Denomination (A) | Case color | Typical purpose in Nissan Juke |
|---|---|---|
| 5A | Orange | Engine control systems, sensors |
| 10A | Red | Front dimensions, horn |
| 15A | Blue | Cigarette lighter, power windows |
| 20A | Yellow | Cooling fan, ABS |
| 30A | Green | Windshield wipers, heated seats |
Particular attention should be paid to fuses responsible for safety systems such as ABS or airbags (SRS). Failure of these could result in warning lights appearing on the instrument panel and loss of critical vehicle functions.
In the block under the hood there are often more powerful fuses that protect power circuits. Replacing them requires greater care, as they are located in close proximity to the battery and high-voltage wiring.
Sometimes the markings on the fuse may be erased due to aging of the plastic or exposure to chemicals. In such cases, it is better to focus on the position in the diagram and the color of the case, and not just on the numbers.
What to do if the denomination does not match?
If you do not find a fuse of the required rating, you can temporarily use an element with a lower current. It will burn faster but will protect the circuit. Never install a fuse with a higher rating.
