Power supply system for car accessories Nissan Sunny is one of the most loaded nodes of the electrical circuit. The cigarette lighter is often used not only for its intended purpose, but also as a power source for DVRs, navigators, chargers for smartphones and compressors. When a device stops working, owners often immediately think about a complex breakdown, but in most cases the problem is solved in a few minutes.
The main element of protection in this chain is fuse. This is a simple device that burns out when the permissible current is exceeded, saving the wiring from fire. On models Nissan Sunny For different years of manufacture, the location of this element may differ slightly, but the principle of operation remains unchanged. Understanding exactly where the fuse box is located and how to properly diagnose it will save you time and money on a service visit.
Location of fuse boxes in Nissan Sunny
By car Nissan Sunny There are usually two main places where protective elements can be located. The first place is located in the cabin, directly next to the steering column or at the end of the dashboard on the driver's side. The second place is the engine compartment where the main mounting block is located. To find the cigarette lighter fuse, you most often need to turn to the interior unit.
To get to the interior unit, open the driver's door and carefully inspect the lower part of the dashboard. There you will see a plastic cover that covers the compartment. On the inside of this cover, as a rule, there is a diagram of the arrangement of the elements. If the sticker is lost or erased, do not panic - the diagram is often duplicated in the car’s service book.
In the engine compartment, the unit is usually located closer to the battery or firewall. However, the cigarette lighter fuse is rarely located there, since it controls the internal electronics. The block under the hood often contains power fuses responsible for the engine, headlights and cooling system. However, if you do not find the element you need inside, check the outside unit as well.
- 🔍 Inspect the plastic cover for a diagram with symbols
- 🔋 Check the location next to the battery in the engine compartment
- 🛠️ Use a flashlight to better illuminate dark areas of the panel
⚠️ Attention: Before starting any work on the car's electrical system, be sure to disconnect the negative terminal of the battery to avoid a short circuit when removing the elements.
How to determine the required fuse according to the diagram
After you open the block, you will be presented with a series of multi-colored plastic elements. Each of them has its own denomination, indicated by a number on the case. You need to find the one that is responsible for the cigarette lighter circuit. On the diagrams Nissan Sunny it is often labeled as Power Socket, CIG (Cigarette Lighter) or ACC.
The cigarette lighter fuse rating is usually 15A or 20A. It is important to know this in advance so as not to confuse it with neighboring elements responsible, for example, for power windows or a radio. If you use a too powerful device through a splitter, the current may exceed the permissible values, which will lead to the burnout of this particular element.
Sometimes the markings on the diagram may not be obvious or erased. In such cases, a multimeter or visual inspection will help. Pull out suspicious items and look at them against the light. A blown fuse has a broken metal bridge inside a plastic casing. The whole element has a continuous arc.

Step-by-step instructions for replacing a burnt-out element
Replacing the fuse with Nissan Sunny - a procedure that does not require professional education. The car often comes with special plastic tweezers, which are attached to the unit cover or placed in the glove compartment. If it is not there, you can use ordinary tweezers or carefully pry the element with your fingernail, but it is better to use a tool so as not to damage the contacts.
First, remove the burnt element by pulling it straight up. Do not swing it too much to avoid breaking the seat. After removing, make sure that the rating of the new fuse is exactly the same as the old one. Installing an element with a lower rating will lead to frequent burnouts, while installing an element with a higher rating can cause a fire in the event of a short circuit.
Insert new fuse all the way. It should fit tightly in the nest. After this, you can turn on the ignition and check the operation of the cigarette lighter. If everything is done correctly, the indicator on the dashboard will light up and the device will begin to heat up or charging the connected gadget will begin to work.
☑️ Check before replacement
⚠️ Attention: Never replace a burnt-out fuse with a “bug” made of wire or foil. This deprives the circuit of protection and creates a direct risk of fire in the vehicle wiring.
Reasons for repeated fuse blowing
If a new fuse blows immediately after installation or after a short time, the problem lies not in the element itself, but in a faulty circuit. The most common reason is connecting too powerful consumers through a splitter. Cigarette lighter Nissan Sunny designed for a certain power, exceeding which causes overheating.
The second reason is a short circuit in the charger wires or in the cigarette lighter connector itself. The internal contacts may become oxidized, carbon-coated, or deformed, resulting in a short between the center contact and ground. It is also possible that the wiring insulation in the connector area may be damaged if it rubs against the metal of the housing.
Sometimes the problem lies in a low-quality accessory. Cheap Chinese chargers often have poor circuit design and can produce pulsed current surges that burn out the protection. It is recommended to use certified accessories from trusted brands.
- ⚡ Check the power of the connected devices (no more than 120-180 W)
- 🔌 Inspect the cigarette lighter connector for carbon deposits or sparking
- 🔋 Replace cheap chargers with high-quality analogues
What to do if the fuse does not blow, but the cigarette lighter does not work?
Perhaps the problem is in the cigarette lighter connector itself. The contacts inside may oxidize or come loose. Try cleaning them carefully with alcohol or bending the central contact. Also check the wire going to the connector for breaks.
Features of the electrical system of Nissan Sunny of different generations
Model range Nissan Sunny spans several generations, and the arrangement of elements may change. On older models (such as the N15 or N16 series), the fuse blocks may have been designed as separate cassettes rather than a single block. Newer versions (N17 and later) use a modern system with integrated modules.
It is important to consider that in some trim levels cigarette lighter fuse Can be combined with power supply for radio or other accessories. In this case, if the element burns out, several devices will stop working at once. This makes troubleshooting easier because you will immediately notice a complex problem.
For accurate identification, always check the documentation for your specific year of manufacture. Vehicles built for different markets (e.g. Europe or the Middle East) may have slight differences in electrical circuitry. Never rely on rumors, but check the facts.
The table below will help you navigate the typical denominations for different versions:
| Year of manufacture | Designation on the diagram | Denomination | Location |
|---|---|---|---|
| 2010-2012 | CIG | 15A | Salon, left side |
| 2013-2016 | Power Socket | 20A | Salon, center panel |
| 2017+ | ACC | 15A | Salon, steering wheel unit |
| All years | Ignition | 25A | Under the hood |
Keep a spare set of fuses of different ratings in the glove compartment. This will save you on the road if the main one burns out at the most inopportune moment.
Diagnostics and testing with a multimeter
If it is difficult to visually determine the condition of the fuse, use a multimeter. Switch the device to the dialing mode (sound wave icon) or resistance measurement mode. Apply probes to the metal contacts of the fuse on both sides.
If the multimeter beeps or shows resistance close to zero, the element is working. If there is no signal or the resistance is infinitely high (shows “1” or “OL”), then the circuit is broken and fuse to be replaced. This method is especially useful for fuses with dark housings where the break is not visible to the eye.
You can also check the presence of voltage at the contacts of the block. Turn on the ignition and touch one probe to the fuse contact and the other to ground (car body). If there is voltage, then power is reaching the unit, and the problem may be in the cigarette lighter connector itself or the wiring after the fuse.
- 🔌 Use dialing mode to quickly check integrity
- 📊 Check the voltage at the contacts with the ignition on
- 🛡️ Make sure the multimeter probes fit snugly against the contacts
Regularly checking the contacts and cleaning the cigarette lighter socket will extend the life of the fuse and prevent frequent blowouts.
Prevention and care of the cigarette lighter system
To avoid frequent breakdowns, you should follow simple operating rules. Do not leave powerful devices (for example, a compressor or a video recorder) on for a long time with the engine turned off, unless this is provided for by the vehicle's design. This can lead to deep battery discharge and overload of the circuit.
Periodically clean the cigarette lighter connector from dust and dirt. Use a can of compressed air or a cotton swab soaked in alcohol. Dirt and oxides create additional resistance, which leads to heating and rapid failure of the elements.
If you plan to install additional powerful devices (for example, an amplifier or additional light), it is better to power them directly from the battery through a separate fuse. Do not overload the standard cigarette lighter circuit, which is designed for low power.
⚠️ Warning: If you smell something burning or see smoke coming from the cigarette lighter socket, immediately unplug all devices and check the fuse and wiring. Don't ignore signs of overheating!
FAQ: Frequently asked questions
Where exactly is the cigarette lighter fuse on a 2014 Nissan Sunny?
On the 2014 Nissan Sunny, the cigarette lighter inverter fuse (CIG) is usually located in the interior fuse box, located to the left of the steering wheel under the dash. Look for a 15A or 20A element labeled Power Socket.
What should I do if the new fuse blows immediately?
If the new element burns out instantly, this indicates a short circuit in the circuit. Check the cigarette lighter connector for carbon deposits or shorted contacts, inspect the wiring for damage to the insulation and avoid using low-quality splitters.
Is it possible to use a fuse with a higher rating if there is no suitable one?
Absolutely not. Installing a higher rated fuse (for example, 30A instead of 15A) may cause the wiring to blow rather than the fuse when overloaded. This creates a serious fire hazard. Use only the item with the rating specified in the instructions.
How to check a fuse without a multimeter?
Visually inspect the element against light. In a working fuse, the metal jumper inside the transparent body is solid. If it is torn or blackened, the fuse has blown. You can also try installing a known-good item.
Why doesn't the cigarette lighter work even though the fuse is intact?
If the fuse is working, the problem may be in the cigarette lighter connector itself (oxidation of contacts, burnout of the central contact) or a break in the wire running from the block to the connector. It is also possible that the device powered through it may be faulty.
