The situation when the cigarette lighter or USB charger in the car stops working Nissan Juke, occurs more often than it seems at first glance. Many car owners immediately suspect a breakdown of complex electronics or a malfunction of the socket itself, but in the vast majority of cases the problem lies in a banal burnout of the protective element of the circuit. This is the easiest and cheapest way to restore the functionality of the gadget power connector.
To fix a problem, you don’t have to go to a service center and pay for diagnostics. It is enough to know exactly where the required fuse is located, what its rating is and how to correctly carry out the replacement procedure. Owners Nissan Juke The first and second generations are often faced with the fact that the fuse box is hidden under decorative trims, which creates the illusion of difficulty of access. In fact, the scheme is arranged logically, and you can figure it out in a few minutes.
It is important to understand that the cigarette lighter in modern cars is not just a place to ignite tobacco, but a full-fledged 12-volt power connector, which is used for navigators, video recorders and chargers. If it stops working, it means that the circuit is broken and the current is not reaching the connector. Most often this happens due to overload when several powerful devices are connected to one connector at the same time.
Localization of the fuse box in the Nissan Juke interior
The first step in troubleshooting is to determine the location of the fuse block. In the car Nissan Juke (F15 body and restyled versions) the main unit is located in the dashboard, on the driver's side. You need to open the door and sit in the driver's seat to inspect the left side panel of the dashboard.
Locate the decorative trim that prevents access to electrical components. It is attached with plastic clips and can be removed without the use of tools, although a little force is sometimes required. Under this panel you will see a rectangular block with a cover, on which a diagram of the arrangement of elements is usually printed. This is the central fuse block, where the cigarette lighter protection is located.
Sometimes owners confuse this unit with an additional one located in the engine compartment. It is important not to confuse them, since the engine compartment contains fuses for more powerful components: the generator, starter and cooling systems. For the cigarette lighter and socket in the cabin, you need the cabin unit. If the unit cover in the cabin is damaged or missing, it will be more difficult to find the required element, so you should take care of its safety.
- 🔍 Inspect the left side of the dashboard next to the driver's doorway
- 🔧 Carefully snap off the plastic cover covering the block
- 📄 Find the diagram on the inside of the fuse box cover
Deciphering the circuit and finding the right fuse
Once you reach the block, you will see many colorful elements of different sizes. In order not to confuse them, you need to carefully study the markings. There is a table on the block cover or in the instruction manual where each fuse is assigned a number and its function is described. Look for designations associated with "CIG", "POWER OUTLET" or "ACC".
In most trim levels Nissan Juke The cigarette lighter is supplied with a fuse rated 15 Ampere or 20 Ampere. Color coding often aids in identification: yellow usually corresponds to 20A and blue to 15A. However, you cannot rely only on color, since during replacement they could have supplied an element of a different denomination.
You need to find exactly the element that is responsible for powering the cigarette lighter socket. If the circuit on the cover is erased or you find it difficult to understand, you can use a multimeter or an indicator screwdriver to check the continuity of the circuit. But most often a visual inspection is sufficient, since the burnt-out element is immediately visible.
⚠️ Attention: Never try to replace a fuse with a higher rated element. This can lead to overheating of the wiring and fire of the car, since the protection will work only after the wires have already begun to melt.
If you find a suspicious element, remove it using a special clamp, which is usually located in or next to the block. Inspect the metal jumper inside the plastic housing. If it is intact and transparent, the fuse is working. If the jumper is torn or traces of soot are visible inside, the element is burnt out and requires replacement.

Step-by-step instructions for replacing the fuse
The replacement process is extremely simple and does not require special electrician skills. The main rule is to perform all actions with the ignition completely turned off. This will eliminate the risk of a short circuit when manipulating the block. Open the hood and make sure that all power consumers are turned off and the key is not in the ignition.
Take a new fuse with exactly the same rating as the one that blew. If you do not have a spare part from your car, you can buy it at any auto store or even at an electronics store. It is important that the amperage matches: do not use 30A instead of 15A. This is a critical time for the safety of your wiring.
Insert the new fuse into the socket until it clicks. Make sure it fits snugly and doesn't wobble. After installation, close the unit cover and return the decorative trim to its place. Turn on the ignition and check the functionality of the cigarette lighter by connecting any working gadget or charger to it.
☑️ Check before installation
If the cigarette lighter still doesn't work after replacing it, the problem may be deeper. It is possible that the heating element in the socket itself has burned out or the contact in the connector has broken. In this case, more complex diagnostics will be required, which is best left to specialists. Sometimes cleaning contacts with alcohol helps if carbon deposits have formed on them.
If you often use the cigarette lighter to power high-power devices, keep a selection of spare fuses of different ratings in the glove compartment. This will save time in case of a sudden breakdown on the road.
Common causes of burnout and prevention
Why does a fuse even blow on such a simple unit? The main reason is exceeding the permissible load on the chain. The cigarette lighter socket is designed to carry a certain current, usually up to 10-12 Amperes of continuous load. If you connect several devices at once through a splitter: a DVR, a navigator, a compressor and a phone charger, the total power may exceed the limit.
Another common reason is the use of low-quality adapters and splitters. Cheap Chinese adapters often have poor insulation and can cause a short circuit even under light load. It is also worth checking the condition of the socket itself: if it is loose and the contacts inside are touching each other, this is guaranteed to trigger the protection.
To prevent such situations, it is recommended not to connect devices with high energy consumption directly to the cigarette lighter without using high-quality stabilizers. If you need to power a powerful compressor or refrigerator, it is better to use a separate line with a direct connection to the battery via a relay.
Regularly checking the condition of the contacts in the cigarette lighter socket and avoiding cheap power strips is the best way to avoid frequent fuse replacements.
Comparative table of denominations for different generations
Owners of different generations Nissan Juke may experience slight differences in labeling and item placement. Although they have a common base, manufacturers sometimes make changes to the electrical circuits. Below is a table that will help you navigate depending on the year of your car.
| Generation/Year | Fuse number | Denomination (A) | Marking on the diagram |
|---|---|---|---|
| F15 (2010-2014) | 15 | 15 | CIG |
| F15 Restyling (2014-2017) | 18 | 15 | POWER OUTLET |
| F16 (2017-2020) | 22 | 20 | ACC SOCKET |
| Special versions | 25 | 10 | USB CHARGER |
Please note that even within the same model year there may be differences depending on the configuration. In top versions with many electronic assistants, the power circuit can be divided into several fuses. Therefore, always check the current diagram specifically for your car, which is in the instructions or on the unit cover.
⚠️ Warning: If you replace a fuse and it blows again within a few minutes, stop using it immediately. This is a sign of a serious short circuit in the wiring that can cause a fire.
In some rare cases, the problem may not be the fuse, but the relay that controls the cigarette lighter circuit. If the circuit includes a relay, check its serviceability. A clicking sound when the ignition is turned on may indicate that the relay is activated, but the contact inside does not close.
What to do if the fuse burns out immediately?
If the new fuse blows instantly after installation, there is a direct short in the circuit. Check the wiring under the dashboard for frayed insulation, especially at the bend when the door is opened. Also check to see if the contacts inside the cigarette lighter socket itself are shorted.
Features of Nissan Juke electrical diagnostics
Electrical system Nissan Juke has its own characteristics that should be taken into account when troubleshooting. For example, some models are equipped with an energy-saving system that can turn off power to the outlet after a certain time after turning off the ignition. If the outlet doesn't work but the fuse is intact, the shutdown timer may have tripped.
It is also worth paying attention to the condition of the battery terminals. A weak connection at the negative terminal can cause strange electronic behavior, including unstable operation of the cigarette lighter. Oxidation of contacts often leads to a voltage drop, which the system perceives as a malfunction.
For accurate diagnostics, you can use a diagnostic scanner, which is connected via the OBD-II port. It will show errors in the power supply system if they were detected by the control unit. However, for simple fuse replacement this method is redundant and requires additional equipment.
- 🔋 Check that the battery terminals are securely fastened
- ⏱ Make sure the outlet is not turned off by the energy saving timer
- 🔧 Use a multimeter to check the voltage in the socket
Why doesn't the USB port work if the cigarette lighter is alive?
USB ports in Nissan Juke often have a separate fuse from the cigarette lighter socket. If the jack works but the USB does not, check the fuse labeled "USB" or "INFO". The problem may also be a software failure of the multimedia system, which can be resolved by rebooting the head unit.
