Troubleshooting in a car's electrical circuit often begins with checking the fusible links that protect the wiring from short circuits. On Nissan Almera For different generations, the location of these elements may differ, which creates confusion among owners. Understanding the structure of the electrical system will allow you to quickly fix problems with lighting, power windows or multimedia systems without a visit to the service center.
Owners Nissan Almera Often we are faced with a situation where one of the components of the car suddenly stops working, and the first suspect is a blown fuse. It is important to know that modern models use not only standard blade fuses, but also specialized relays and power units that require special attention during diagnostics.
Main blocks of electrical equipment protection
In design Nissan Almera There are two main locations for fuses: in the engine compartment and in the vehicle interior. Each of these blocks is responsible for specific groups of electricity consumers, and knowledge of their functions is critical for quick diagnosis. Main fuse box usually located in the engine compartment next to the battery.
The second block is responsible for internal comfort systems, is located directly in the salon. It is often hidden behind a decorative panel on the left side of the steering column or behind a cover at the bottom of the dashboard. Some models may have additional additional relays in the center console, but the main elements are concentrated in the two listed places.
To access the elements in the engine compartment, you need to open the hood and unfasten the plastic latches of the black box lid. Inside you will see a diagram showing the purpose of each element. If the circuit is erased, you will have to use a multimeter to check the continuity of the circuit, since a visual check does not always show the internal state of the fuse link.
Location in the engine compartment
In the engine compartment Nissan Almera The fuse box is a sealed plastic case, protected from moisture and dust. It is located close to the battery, which allows it to control the power supply to power units such as cooling system, starter and generator. The cover of this block usually has a relief arrangement of elements.
If you need to check the fuses responsible for the operation of the headlights or radiator fan, you should look at those with a high current rating (from 30 to 80 Amps). These fuses are large in size and often differ in color from standard low-voltage fuses. Power fuses require more careful handling when removing.
Sometimes access to certain fuses may be difficult due to the proximity of other units. In this case, it is recommended to use extended tweezers, which often come with the block. Do not try to pull out the fuses with your hands if they are tightly seated, as you may damage the contact groups or adjacent elements.
Internal fuse box in the cabin
Inside the car, access to the fuses is through a special cover located on the dashboard on the driver's side. On Nissan Almera of the new generation, this panel can be hidden behind a decorative overlay, which must be carefully pryed off with a screwdriver or plastic card. Under the lid is electrical control unit salon
Here are the fuses responsible for cigarette lighter, window lifters, audio system and airbags. Current ratings here are generally lower (5 to 20 Amps), which corresponds to the load on the internal electronics. It is important not to confuse the cigarette lighter fuse with the radio fuse, since their purpose may vary depending on the model year.
A diagram is often pasted on the back of the block cover to help identify each element. If the sticker is missing or damaged, please refer to the technical documentation. Remember that incorrect replacement may cause more complex electronics to burn out rather than simply trigger the protection.
⚠️ Attention! Before removing the fuse from the indoor unit, be sure to turn off the ignition and all electrical appliances in the cabin. This will prevent an accidental short circuit when removing the element.

Fuse diagram and decoding
Understanding fuse labeling is key to successful diagnosis. On the body of each element there is a number indicating the maximum current in Amperes that it can withstand. For example, a fuse marked 10A will burn out when the current exceeds 10 Amps, protecting the circuit from overload. Color coding also helps to quickly determine the denomination: yellow - 20A, red - 10A, blue - 15A.
Below is a table with the main fuses that most often raise questions among owners Nissan Almera. This information applies to most models, but always check with your specific circuit.
| Designation | Denomination (A) | Purpose | Location |
|---|---|---|---|
| F1 | 10 | Headlights (low beam) | Salon |
| F12 | 20 | Cigarette lighter and 12V socket | Salon |
| F35 | 15 | Window lifters | Salon |
| EF1 | 40 | Electronic engine control unit | Under the hood |
| EF5 | 30 | Cooling fan | Under the hood |
Please note that some fuses may have dual purposes or be duplicated in different blocks. For example, power for the rear lights can go through the main unit under the hood, and they can be controlled through the interior unit. This makes troubleshooting difficult if you do not know the exact wiring diagram.
What to do if the fuse is not blown, but the device does not work?
If the fuse is visually intact, but the device does not function, the problem may be in the relay or the consumer itself. Check the relay for clicks when turned on. It is also possible that the contacts in the fuse holder may oxidize, which requires cleaning the contacts with alcohol or a special cleaner.
Rules for diagnosis and replacement
The process of replacing a blown fuse seems simple, but requires following a certain sequence of steps for safety. First, you need to visually inspect the fuse link: if the metal jumper inside is torn, the element must be replaced. However, visual inspection is not always accurate, so using multimeter in dialing mode is the most reliable method.
When replacing, it is strictly forbidden to use fuses with a higher current rating than indicated in the diagram. This may cause the wiring to melt and cause a fire. If you do not have a suitable element at hand, you can temporarily use a fuse with a lower rating, but this will reduce the reliability of the circuit. Replacement with "bug" or wire is unacceptable under any circumstances.
If a new fuse blows immediately after installation, this indicates a serious fault in the circuit: a short circuit or overload. In this case, further operation of the car is impossible without repairing the wiring. Ignoring this problem will lead to failure of expensive electronic control units.
⚠️ Attention! Never use metal objects such as paper clips or nails to temporarily short circuit contacts. This is a direct path to a fire in the engine compartment at the slightest voltage surge.
☑️ Fuse replacement procedure
Common causes of blown fuses
Understanding the reasons why the protection is triggered will help prevent repeated breakdowns. The most common reason is short circuit in the wiring caused by damage to the insulation or moisture ingress. Moisture often gets into connectors located in doors or under the dashboard, especially on used cars.
Another common cause is connecting high-power external devices, such as audio amplifiers, additional lights or dash cams, without using a separate circuit with an appropriate fuse. When installing additional equipment Always calculate the load and select the wire cross-section and protection rating correctly.
Worn contacts in the fuse holder can also cause the insert to overheat and burn out. Over time, the metal oxidizes, resistance increases, and even under normal load the fuse may blow. Regular checking and cleaning of contacts will extend the life of the electrical system.
If the cigarette lighter fuse is blown, check the devices connected through it. Often the cause is a low-quality phone charger, which creates a surge in current when the ignition is turned on.
Specifics of Nissan Almera models of different years
Owners Nissan Almera different generations (G15, N18, etc.) may encounter differences in the location of the blocks. In older models, the circuit could be simpler, while in new generations the number of electronic modules has increased significantly. This led to additional relay blocks and more complex markings.
For example, in the model Nissan Almera N18 The interior fuse box can be integrated into the climate control panel or located in a niche for small items. Always check the technical documentation specific to your year of manufacture. Global Platform B0, on which modern Almera is built, has its own specifics in electrical engineering.
It is also worth noting that in some markets (for example, in Russia or China), configurations may differ, which affects the availability of certain fuses. If you have a version with air conditioning but no climate control, the layout may differ slightly from the version with a full range of options.
Modern Nissan Almera models require a more careful approach to electrical systems due to the integration of many electronic units, so diagnostics often require the use of specialized equipment, and not just a visual inspection.
DIY Tools
To replace fuses and check the electrical circuit yourself, you will need a minimum set of tools. The main tool is car tweezers, which is usually inserted into the fuse box cover. If you don't have one, you can use regular tongs with insulated handles.
For in-depth diagnostics, you will need a multimeter capable of measuring voltage and resistance. This will allow you not only to check the integrity of the fuse, but also to find the location of the short circuit in the wiring. It is also useful to have a set of Phillips and flathead screwdrivers for removing decorative panels.
It would be a good idea to have a spare set of fuses of different ratings. They are inexpensive, but can save you on the road if a critical element burns out. Store them in a sealed bag to avoid oxidation of the contacts.
How to check a fuse without a multimeter?
If you don’t have a multimeter at hand, you can use a test light (probe). Connect one end to the body (ground), and the other end touch the fuse contacts with the ignition on. If the lamp lights up on one side but not the other, the fuse has blown.
FAQ: Frequently asked questions
Where is the cigarette lighter fuse on a Nissan Almera?
It is usually located in the cabin, in a block on the left side of the steering wheel. The markings are often designated as "CIG" or "ACC". On some models this is a 20 Amp fuse (red).
What should I do if the fuse blows immediately after replacement?
This indicates a short circuit in the circuit or a consumer fault. Do not attempt to replace it with a higher rated fuse. It is necessary to check the wiring and the device that it powers.
Can I use a different color fuse?
No, the color corresponds to the current rating. Using a fuse with a lower rating (for example, a blue one instead of a red one) can lead to frequent fuse blowing, and using a larger one can lead to the risk of a wiring fire.
How to check the fuse visually?
Pull it out with tweezers and look at the transparent body. If the metal bridge inside is torn or melted, the fuse is faulty. The integrity of the jumper is the only visual sign of serviceability.
Where can I find a fuse diagram for my model?
The diagram is usually pasted on the inside of the fuse box cover. If the sticker is missing, consult your owner's manual or find an electronic version of the diagram for your VIN on the Internet.
