The presence of a blown fuse is one of the most common causes of sudden failure of electrical devices on a car. Nissan Almera Classic. Owners are often faced with a situation where a power window, radio or interior lighting stops working, not suspecting that the problem can be solved in a couple of minutes by simply replacing the protective element.
Understanding how electrical protection works in your car, allows you to save time and money by avoiding visits to a service station for every little thing. Fuse diagram this model has its own characteristics characteristic of the B10 platform, and knowledge of the location of the blocks is critical for quick diagnosis.
Location of main protection units
On Nissan Almera Classic electrical protection is distributed between two main areas: the engine compartment and the vehicle interior. Do not try to look for all the elements in one place, since the power circuits are protected separately from low-voltage consumers. The main unit, responsible for the generator, headlights and fans, is located under the hood.
The second unit, located in the cabin, protects devices such as the cigarette lighter, audio system, power windows and interior lighting. It is accessed through a removable cover on the driver's side, just under the steering column. You simply pull the latches to access the fusible links.
It is important to note that the engine compartment also contains relays that control the operation of powerful components. Block body in the engine compartment should be sealed, but when replacing fuses, the cover can be easily removed by unfastening the latches. Do not forget to turn off the ignition before starting work.
Diagnostics and visual inspection of fuses
Before replacing the element, you need to make sure that it is really burned out. Visual inspection is the most reliable method that does not require additional equipment. Take the removed fuse and look at its transparent body in the light.
If the metal jumper inside is torn or melted, it means the chain is broken, and the part must be replaced immediately. Sometimes a break is so subtle that it requires the use of a multimeter in continuity mode or a tester to accurately determine the fault. On Nissan Almera standard pin fuses are used in different colors to indicate the rating.
If the element is visually intact, but the device still does not work, the problem may be in the device itself, wiring or relay. Do not rush to install a known good fuse from another unit if you are not sure of the cause of the failure. This can lead to short circuits and failure of more expensive equipment.
⚠️ Attention: Never use pieces of wire, paper clips or bugs to replace a fuse! This will instantly cause the wiring to overheat and may cause the car to catch fire.
To make it easier to find a faulty element, a diagram indicating the current strength is often printed on the back of the block covers. However, during use, stickers may wear off or come off. In such cases, the detailed transcript below will help you.

Decoding the fuses in the cabin
Block in the cabin Nissan Almera Classic responsible for the operation of most comfortable systems. Each fuse here has its own code (F1, F2, etc.) and rated current. Below is a table of the main elements with which owners most often have questions.
Please note that some fuses may be duplicated or shared circuits with other systems. When replacing, always check the rating indicated on the element body. Installing a fuse with a higher rating is strictly prohibited.
| Designation | Denomination (A) | Purpose | Key consumers |
|---|---|---|---|
| F1 | 10 | Right headlight (high beam) | Incandescent lamp |
| F4 | 15 | Cigarette lighter | Adapters, chargers |
| F7 | 10 | Interior electronics | Lighting, alarm |
| F12 | 25 | Window lifters | Front door motors |
| F15 | 15 | Audio system | Radio, amplifier |
Particular attention should be paid to the cigarette lighter fuse. Often, car owners connect powerful inverters or chargers through it, which quickly damages the element. If your phone charging is not working, first check F4.
There is also a separate fuse for the window regulators. If the windows stop opening or closing, check the integrity of element F12. In some cases, the problem may be with the control buttons, but more often than not, network congestion is to blame.
Before replacing a fuse, always turn off the ignition and disconnect consumers to avoid a short circuit when installing a new part.
Power fuses under the hood
The block under the hood contains more powerful elements that protect the circuits of the generator, starter, cooling fans and fuel pump. Access to it is simple: just unfasten the plastic clips on the black case located next to the battery.
Both conventional pin-type fuses and larger elements (poppy fuses) with a high rating are used here. Power circuits require special attention, since an error in their operation can lead to the engine stopping while moving. Read the label carefully before replacing.
The main elements located in this block:
- 🔋 MAIN — protection of the main power circuit and generator (80-100 A).
- 🌡️ COOLING FAN — cooling system fan protection (30-40 A).
- ⛽ FUEL PUMP — fuel pump protection (15 A).
- 💡 HEADLIGHT — protection of low and high beam headlight circuits.
If your engine does not start, but the starter turns, check the fuel pump fuse. If the engine stalls while driving, the ignition or fuel supply system protection may have tripped. In such cases, it is important to quickly find and eliminate the cause of the overload.
☑️ Checking the engine compartment
⚠️ Attention: The unit under the hood contains high-voltage elements. Do not touch battery terminals or power conductors while working on electrical equipment.
