Problem with a non-working cigarette lighter on a car Nissan Almera new generation (G15) is more common than it seems at first glance. Many owners immediately run to the service center, thinking about a serious breakdown of the wiring or power controller, although in 90% of cases the reason lies in a banal burnt out fuse. It is a protective circuit element that sacrifices itself to save expensive electronics from a power surge or short circuit when connecting a high-power device.
Understanding that where is the right element of protection will save you time and money. Unlike older models, Nissan Almera G15 blocks are conveniently located, but the marking scheme may not be obvious to a beginner. You will need to find two main components: the engine compartment unit and the interior unit, located on the left side of the steering wheel.
Location of fuse boxes on Nissan Almera G15
By car Nissan Almera G15 has two main locations for placing electrical circuit protection elements. The first is located in the engine compartment, in a special plastic box, protected from moisture and dirt. The second is located directly in the cabin, which makes it more accessible for quickly diagnosing problems with accessories such as the cigarette lighter or chargers.
It is important to note that the cigarette lighter and auxiliary 12V socket circuits on this model are most often protected by the interior unit. However, if the problem cannot be solved by replacing the cabin fuse, it is also necessary to check the engine compartment, since on some trim levels the power lines may be duplicated or have a specific wiring.
To access the interior unit, you need to open the driver's door and find the cover on the left side of the steering column, in the area of the pedals. It covers the assembly where the main relays and fuses are located.
The engine compartment is located on the right (passenger's side) in the engine compartment, closer to the windshield. The cover of this block has a relief surface and is secured with latches.
Before starting any manipulations, make sure that the ignition is turned off and the keys are out of the lock. This will eliminate the risk of a short circuit when removing elements.
- 🔍 Interior unit: to the left of the steering wheel, under the instrument panel.
- ⚙️ Engine compartment: on the right in the engine compartment, next to the battery.
- 🔑 Tools: tweezers or thin screwdriver, multimeter.
How to find the cigarette lighter fuse according to the diagram
Each block on Nissan Almera G15 is equipped with a circuit on the inside of the cover. This diagram is your main navigator. You need to carefully study the pictograms and inscriptions corresponding to the fuse ratings. Nissan diagrams often use English abbreviations, which can be confusing to an untrained driver.
Typically the cigarette lighter circuit is designated as POWER OUTLET or CIG (from the word Cigarette). In some cases, if the outlet is duplicated in the passenger compartment and in the trunk, they may be powered from one unit or have separate fuses. On Nissan Almera G15 the most likely candidate is a fuse rated 15A or 20A.
If you don't see an obvious "CIG" designation on the diagram, look for labels related to power outlets or accessories. Sometimes a manufacturer combines several consumers into one circuit.
The most reliable way is to use the correspondence table below to quickly identify the desired element without long searches through small hieroglyphs on the diagram.
| Purpose | Designation on the diagram | Denomination (A) | Location |
|---|---|---|---|
| Cigarette lighter / 12V socket | POWER OUTLET / CIG | 15 | Salon block |
| Cigarette lighter / 12V socket | ACC SOCKET | 20 | Salon block |
| Add. food (trunk) | TRUNK SOCKET | 15 | Salon block |
| Power circuit (common) | MAIN FUSE | 30-40 | Engine compartment block |
Please note that the fuse rating must exactly match that shown on the diagram. Installing an element with a higher rating may lead to a fire in the wiring.

Step-by-step instructions for replacing the fuse
The process of replacing a security element with Nissan Almera G15 does not require deep knowledge in electrical engineering and takes no more than five minutes. The main rule is to act carefully and not use excessive force so as not to break the fragile latches of the plastic case. You will need special tweezers, which are usually attached to the side of the fuse box itself, or a thin flathead screwdriver.
First remove the unit cover. To do this, you need to carefully release the latches located around the perimeter of the cover. Do not pull sharply to avoid damaging the plastic ears. After removing the cover, carefully inspect the inside: there is often a spare set of fuses and tweezers.
Find the correct fuse using the diagram or table we made earlier. Visually check its integrity: the metal jumper inside the transparent case should be intact.
If the jumper is torn or melted, the element is burnt out and requires replacement. Remove it with tweezers by pulling straight up, without swaying to the sides.
Install a new fuse of the same rating until you hear a characteristic click. Make sure it fits snugly and doesn't wobble.
☑️ Check before replacement
What to do if there is no new fuse?
If you don't have a spare fuse, you can temporarily use a lower rated element (eg 10A instead of 15A) just to test the circuit. But remember that it may burn out again when the load is turned on. Do not use elements with a high rating under any circumstances, this is dangerous for the car.
Diagnostics: why the fuse blows
If you replace a fuse and it immediately blows, the problem is not with the element itself, but with the circuit. This is a signal that there is a short circuit somewhere or a device is connected that is consuming too much power. On Nissan Almera G15 A common cause is the use of cheap car chargers that create voltage surges when turned on.
The problem may also lie in the cigarette lighter housing itself. Over time, the contacts inside can oxidize or become deformed, which leads to a short circuit between positive and ground. In such cases, simply replacing the fuse will not work, and the socket itself will need to be repaired.
Often the culprit is a low-quality adapter that is inserted into the socket and remains there permanently. Even if you don't use it, it can create parasitic load.
Check the wiring to the cigarette lighter, especially if the car has recently had an additional alarm or audio system installed. Incorrect installation often compromises the wire insulation.
⚠️ Attention: If the new fuse blows instantly when you turn on the ignition, stop testing immediately and contact an auto electrician. Attempts to bypass the protection may result in a fire.
- 🔌 Poor quality chargers with unstable voltage.
- ⚡ Closing the contacts inside the cigarette lighter socket itself.
- 🔧 Errors when installing additional equipment (alarm, radio).
Features of the electrical circuit Nissan Almera G15
Electrical diagram Nissan Almera G15 has its own nuances that should be taken into account when diagnosing. Unlike some competitors, here the cigarette lighter circuit can be protected not only by a fuse, but also by a relay. The relay provides more reliable control of high current by relieving the load on the switch itself or the control circuit.
Sometimes the problem lies not in the fuse, but in the oxidation of the contacts in the relay block. This may occur due to condensation or moisture entering the engine compartment. Visually it looks like a greenish coating on the metal legs of the elements.
On some versions of the G15, the cigarette lighter socket is powered directly from the battery via a relay, which means that it can operate even when the ignition is off unless the energy saving system is configured.
This is important to know if you leave your navigator or video recorder on in a parking lot. Constant load on the battery can lead to its discharge if the car sits without driving for several days.
Before purchasing a new fuse, be sure to check the rating of the old one. Even if it appears intact, its performance may have degraded over time due to overheating.
How to check the integrity of a fuse with a multimeter
A visual inspection does not always provide a 100% guarantee of the element’s serviceability, especially if the jumper inside is very thin or slightly damaged. For accurate diagnosis, it is better to use a multimeter. This device will allow you to determine the presence of a circuit (resistance) without removing the element from the socket, if you have access to the contact pads.
Set the multimeter to continuity mode (diode or sound wave icon). Touch the probes to the metal contacts of the fuse. If the device makes a beep, the circuit is intact. If there is no signal, the fuse has blown.
If you are testing a fuse that has already been removed, simply place the probes on its side metal legs. This is the easiest and fastest way to check.
Using a multimeter allows you to accurately diagnose a fault, eliminating false conclusions based only on visual inspection.
⚠️ Attention: Never close the fuse contacts with a metal object (paper clip, wire) to check the operation of the circuit. This will cause an instantaneous short circuit and may damage the vehicle's ECU.
If the multimeter shows a break, but visually the fuse appears intact, this may indicate a microcrack in the metal or oxidation of the contacts. In this case, it is better to immediately replace it with a new one, since the resistance in this case will be too high.
Prevention and operating tips
To avoid frequent fuses blowing, follow a few simple rules for operating the electrical system. Nissan Almera G15. First of all, do not use cheap Chinese adapters and chargers without surge protection. They often cause short circuits.
Periodically check the condition of the cigarette lighter socket. If you notice that it gets hot or sparks when you connect the device, this is a sure sign that the contacts are burnt. In this case, it is necessary to clean or replace the socket itself.
- 🛡️ Use only certified chargers with overload protection.
- 🧹 Regularly clean the cigarette lighter socket from dust and small debris.
- 🔋 Do not leave powerful consumers turned on with the engine turned off for a long time.
If you often use the cigarette lighter to connect a DVR or navigator, consider installing a separate power supply with its own fuse, connected directly to the battery.
This will relieve the standard cigarette lighter circuit and reduce the risk of overheating of the wiring. This approach is especially relevant for owners who use the car as a working tool and load the electrical grid to the maximum.
Can I use a higher rated fuse?
Absolutely not possible. The fuse is designed to protect wiring of a specific cross-section. If you put a 30A element instead of 15A, the wiring may burn out, but the fuse will remain intact. This is a direct fire hazard.
