Car owners Nissan Almera N16 generations are often faced with a situation where one or another electrical consumer stops working: from power windows to the ignition system. In most cases, the problem lies not in a complex breakdown, but in a burnt-out protective element. Knowing the exact location of the blocks and their internal layout allows you to quickly restore the vehicle’s functionality without a visit to the service center.
Power supply system Nissan Almera N16 built according to the classical scheme using fusible links and relays. The location of the blocks is distributed throughout the cabin and engine compartment, which requires the driver to be attentive when searching for the desired element. Understanding the logic of electrical operation will help you save time and money on diagnostics.
Localization of fuse and relay blocks
By car Nissan Almera N16 provides two main installation locations for protective elements. The first unit is located in the cabin, and the second is located directly in the engine compartment. This separation allows high-voltage engine circuits to be isolated from low-current comfort and interior circuits.
The main cabin unit is located under the instrument panel on the left side of the steering column. To access it, you need to carefully unscrew the plastic cover, which is secured with latches. A schematic decoding is usually printed on the inside of the lid, but it can be erased over time due to frequent opening.
The second unit, responsible for powering powerful units, is located in the engine compartment. It is located in a black plastic case to the right of the engine, closer to the mudguard. The cover of this unit also contains markings, but they are often less readable than in the interior version. Access to it is free, just open the hood.
It is important to note that depending on the year of manufacture and configuration, Nissan Almera N16 may have slight differences in layout. Restyled versions sometimes receive additional relays or change the location of some fuses. Always check the actual presence of elements on the board, and not just the schematic diagram.
⚠️ Warning: Before beginning any fuse replacement work, be sure to disconnect the negative terminal of the battery to eliminate the risk of short circuit and electrical shock.

Interpretation of the main interior fuses
Salon block Nissan Almera N16 contains protection elements for comfort systems, lighting and electronic control units. The most common fuses that blow are those responsible for the cigarette lighter, power windows and audio system. These elements have ratings from 5 to 15 Amps and are easily changed by hand.
To diagnose a malfunction, it is necessary to visually inspect the fuse link. The integrity of the metal jumper inside the transparent case is the main criterion for performance. If the jumper is torn or the plastic inside is blackened, the element must be replaced immediately.
- 🔋 F1 (10A) - Power supply to the engine control unit (ECU) and ignition system
- 💡 F4 (15A) – Cigarette lighter and 12V socket for accessories
- 🎵 F5 (10A) - Radio, audio system and multimedia
- 🪟 F10 (20A) — Power windows for front doors
Particular attention should be paid to the fuse F12, which is responsible for the side lights and dashboard lighting. If it burns out, you may encounter a situation where the headlights work but the instrument panel does not light up, which makes driving at night difficult. Also worth checking F15, responsible for the operation of the air conditioner and heater fan.
Elements are replaced using special tweezers, which are usually attached to the block or located in the glove compartment. Use only fuses of the same rating as the one that blew. Installing an element with a higher amperage can lead to a fire in the wiring due to a short circuit.
☑️ Checking the interior unit
Engine compartment and high current circuits
In the engine compartment Nissan Almera N16 fuses and relays are concentrated to ensure the operation of critical engine and safety systems. This is where the high current rating components are located to protect the starter, alternator, fuel pump and cooling system.
The housing of the engine compartment is sealed, which protects the contacts from moisture and dirt. However, with prolonged use, the seal may wear out, which will lead to oxidation of the fuse legs. Regular inspection of this unit is recommended during each maintenance.
Key elements in this block include:
- 🚀 MAINS (80A/100A) - Main fuse that powers the entire on-board network
- ⛽ FUEL PUMP (15A) - Fuel pump and injection system
- ❄️ COND FAN (30A) — Radiator and air conditioning fan
- 💡 HEAD (15A/20A) — Headlights (left and right)
The main fuse plays a special role MAINS. If it burns out, the car loses power completely and the engine will not start. In such cases, professional diagnostics are often required to determine the cause of the short circuit in the main circuit.
What to do if there is no spare fuse?
In an emergency, you can use a lower value fuse from a circuit that is not critical to driving (for example, from the heated seats or cigarette lighter circuit). Never install a fuse with a higher rating than required, as this will burn out the wiring.
Conformity and rating table
To make it easier to find the required element, below is a summary table of the main fuses, which is relevant for most modifications Nissan Almera N16. Data may vary slightly depending on market and year of manufacture.
| Designation | Denomination (A) | Purpose | Location |
|---|---|---|---|
| F1 | 10 | Engine control unit (ECU) | Salon |
| F2 | 10 | Windshield wipers (windshield wipers) | Salon |
| F3 | 15 | Rear wiper | Salon |
| F4 | 15 | Cigarette lighter | Salon |
| FUEL | 15 | Fuel pump | Under the hood |
Please note that the table shows standard values. If your car has specific equipment, such as an auto alarm or auxiliary lights, they may have their own separate fuses that are not installed according to the factory design.
When replacing a fuse in the table, always check the color of the element body with the rating: red - 10A, blue - 15A, yellow - 20A. This is the standard color coding used on most Nissan vehicles.
Troubleshooting and Diagnostics
If after replacing the fuse it blows again within a few seconds, this is a sure sign of a short circuit in the circuit. In this case, further attempts to start the engine or turn on the equipment are unacceptable.
It is necessary to carefully check the wiring for mechanical damage, melted insulation or short to ground. Often the cause is rodents damaging wiring harnesses in the engine compartment, or poor installation of additional equipment.
For accurate diagnostics, it is recommended to use a multimeter in dial mode. Check the resistance of the circuit from the fuse to the consumer. If the resistance is close to zero, then there is a direct short somewhere in the circuit.
It's also worth checking the relay. Sometimes the problem is not the fuse link, but sticky relay contacts that create an overload. Replacing the relay with a known good one will help isolate the fault.
Before replacing a fuse, always remove it completely and inspect the side contacts. Oxidation of the legs can lead to poor contact and false alarms.
Frequent errors during replacement and maintenance
Many owners Nissan Almera N16 make the same mistake: they try to replace the fuse with improvised means, such as paper clips, wire or foil. This is strictly prohibited, as it deprives the circuit of protection.
The use of “bugs” leads to the fact that in the event of a short circuit, the wiring does not have time to burn out, but the insulation melts, causing a fire. Always use only certified fuses of the correct rating.
Another common mistake is installing an oversized fuse “just in case.” For example, replacing a 15-amp element with a 20-amp element. This can lead to the failure of the most expensive equipment that was supposed to be protected.
It is also important not to mix up fuses if they have the same rating. Some chains may be interchangeable, but others are not. Always refer to the diagram on the unit cover.
Correctly replacing a fuse is not just installing a new element, but diagnosing the cause of the burnout. If a fuse blows repeatedly, the problem is deeper than just a random failure.
Additional relays and their role
In addition to fuse links, in blocks Nissan Almera N16 many relays installed. They control the switching of high currents without loading switches and buttons. Relays often fail due to contact sparking or overheating.
The main relays include the starter relay, cooling fan relay, fuel pump relay, and light relay. If a relay is suspected of being faulty, it can be replaced with a similar one from another circuit (if they are the same in configuration) for testing.
The sound of a relay clicking when the ignition is turned on or the unit is operating is a sign of its serviceability. If the relay clicks, but the equipment does not work, the problem may be in the contacts or the consumer itself.
Installing the wrong relay can cause a short circuit and damage the control unit.
How to check a relay without instruments?
The easiest way is to replace the suspicious relay with a known good one from another circuit (for example, from a signal circuit). If the problem disappears, then the relay was faulty.
