One of the frequent problems of owners is the failure of electrical equipment, and in 80% of cases the cause is blown fuses. However, finding an up-to-date fuse box diagram for this model is not easy: operating instructions often lack detailed descriptions, and information on forums is scattered and contradictory.

In this article we have collected full fuse diagram Almera N16 taking into account all modifications (including the 2003 restyling), indicated the exact locations of the mounting blocks and gave practical advice on diagnostics. You will learn which fuse is responsible for the cigarette lighter, why the stove fan may not work, and how to avoid mistakes when replacing. The material is based on official service manuals Nissan and experience of auto electricians.

Where are the fuse boxes in Nissan Almera N16

B Almera N16 provided two main mounting blocks with fuses and relays. Their location depends on the year of manufacture and configuration, but in 95% of cases the diagrams are identical. Below are the exact coordinates for the search:

• 🔧 Main unit (interior): located to the left of the steering column, under the plastic cover. To gain access, pull down on the tab on the cover and it will pop open without tools.
• 🔋 Additional block (under the hood): located next to the battery, in a plastic box with a lid. On some modifications (for example, with air conditioning) there may be a compressor relay here.

Important: on right-hand drive vehicles (for example, Japanese-built), the interior fuse box may be located to the right of the steering column. Also on cars 2005–2006. sometimes there is a third mini-unit under the glove compartment - it is responsible for the audio system and alarm system.

If you can't find the block, please take a look at cover marking: on original parts Nissan Usually there is a diagram with fuse numbers. On fakes or after replacing the cover, such a pattern may not be present.

Interior block fuse diagram (2000–2006)

Below is full decoding of the fuses of the main unit for Almera N16 all modifications. The fuse numbers correspond to the markings on the cover. If you have a different order, check the inscriptions on the block itself.

Fuse no.	Denomination (A)	Purpose	Notes
1	10	Side lights (left side), license plate light	If burnt out, also check the relay K1
5	15	Cigarette lighter, 12V socket	Often fails when using powerful devices (for example, compressors)
10	10	Engine control unit (ECU), fuel injectors	When replacing, disconnect the battery!
15	20	Heater fan, heated rear window	If the stove does not work, also check the relay K5
20	7.5	Audio system, antenna, clock	When replacing, the radio settings will be reset

Please note: on vehicles with automatic transmission there may be an additional fuse in the block No. 25 (10A), responsible for automatic transmission solenoids. On mechanics, this slot is usually empty.

How to check a fuse without a tester?

If you don’t have a multimeter at hand, you can visually inspect the fuse in the light - the blown thread will be broken. You can also use the “replacement method”: temporarily install a known-good fuse with the same rating from another slot (for example, from the glove compartment light fuse).

Common problems and their causes

Owners Almera N16 often encounter typical faults related to fuses. Here TOP-5 problems and their possible reasons:

• ⚡ Cigarette lighter doesn't work: fuse blown No. 5 (15A) or the contacts in the socket have oxidized. Also check the wires under the glove compartment - they may fray.
• 💡 Dimensions on one side do not light up: fuse No. 1 or No. 2 (10A), or the problem is in the lamp or socket.
• 🔥 Heater fan does not turn on: fuse No. 15 (20A) or relay K5. If the fuse is intact, check the heater motor (it often jams).
• 🎵 The radio doesn't work: fuse No. 20 (7.5A) or a break in the wiring harness behind the glove compartment.
• 🚗 The engine does not start, the starter does not turn: check the fuse No. 10 (10A) (ECU) and starter relay K3. The battery may also be low.

Particular attention should be paid fuse No. 10 (10A)responsible for ECU. If it burns out, the engine may stall while driving. The cause is often a short circuit in the wiring harness under the hood or a faulty oxygen sensor.

How to properly replace a fuse: step-by-step instructions

Replacing the fuse in Almera N16 - a simple procedure, but there are several nuances that will help you avoid mistakes. Follow this instruction:

1. Turn off the ignition and remove the key from the lock. If the fuse is connected to ECU (For example, №10), it is better to disconnect the negative terminal of the battery.
2. Remove the unit cover: Press the latch at the bottom of the cover and pull it towards you.
3. Find the faulty fuse: Use the diagram above or check visually (the burnt thread will be visible).
4. Remove the fuse: use special tweezers that come with the car (usually found in the glove compartment) or pliers with insulated handles.
5. Install a new fuse the same denomination. Never use wire bugs!
6. Check circuit operation: Turn on the ignition and check if the problem is corrected.

If after replacement the fuse blows again, this means that there is a fault in the circuit. short circuit. In this case it is necessary:

1. Check the wires for damage (especially in kinks).
2. Disconnect consumers connected to this fuse (for example, additional equipment).
3. Contact an auto electrician for diagnostics with a multimeter.

Relay in Nissan Almera N16: location and purpose

Together with fuses in mounting blocks Almera N16 located relay, which are responsible for controlling powerful consumers (starter, fans, headlights, etc.). Below is a relay diagram for the interior unit:

Designation	Purpose	Symptoms of a problem
K1	Side light relay	Dimensions do not turn on or are constantly on
K3	Starter relay	The starter does not turn or clicks
K5	Heater Fan Relay	The stove does not blow or only works at maximum speed
K7	Heated rear window relay	The heating does not turn on or only turns on every once in a while

To test the relay you can use replacement method: Temporarily install a known good relay from another slot (such as a horn relay K6, if it is included in your configuration). If after replacement the problem disappears, the old relay is faulty.

You can also check the relay with a multimeter:

1. Set the resistance test mode (ohmmeter).
2. Connect the probes to the contacts 85 And 86 (relay coil). Resistance must be within 50–120 Ohm.
3. Apply voltage 12V to contacts 85 And 86 — a clicking sound should be heard (relay activation).

⚠️ Attention: When replacing the starter relay (K3) never touch contacts at the same time 30 And 87 metal tools - this will cause a short circuit!

Additional fuses and relays under the hood

In addition to the cabin unit, in Almera N16 under the hood there is additional mounting blockwhich is often ignored in diagnosis. It is located next to the battery and contains:

• 🔋 Main fuse (usually 80–100A) - protects the entire on-board network.
• 💨 Cooling fan relay - if it fails, the engine may overheat.
• ❄️ A/C compressor relay (if the car is equipped with climate control).
• 🔦 Generator fuse (60A) - when it burns out, the battery does not charge.

Particular attention should be paid main fuse (usually designated as Fusible Link). It is a thick fusible wire in a plastic sheath. If this fuse blows, all of the vehicle's electronics are disabled. Reasons:

• Short circuit in the generator circuit.
• Incorrect battery connection (reversed).
• Damage to the insulation of the power cable from the generator to the battery.

Replacement Fusible Link Requires soldering or the use of special connectors. It is not recommended to replace it with regular wire - this may cause a fire!

Common mistakes when working with fuses

Even experienced car owners sometimes make mistakes that can lead to serious damage. Here what not to do when working with fuses Almera N16:

• 🔥 Install a fuse of a higher rating (For example, 20A instead of 10A). This could fry the wiring!
• 🛠️ Use bugs made of wire or foil. At best, this will lead to re-burnout, at worst - to a fire.
• 🔋 Replace fuses with the ignition on. This may cause a power surge and damage ECU.
• 💧 Try to clean oxidized contacts with sandpaper. This will remove the protective coating and accelerate corrosion. Use special contact fluid.
• 🔍 Ignore repeated fuse blown. If the fuse blows again, there is a short circuit in the circuit and must be repaired!

Another common mistake is confusing fuses with relays. The relay looks like a small box with legs, and the fuse is a clear plastic case with a metal thread inside. If you try to replace a relay with a fuse (or vice versa), not only will it not help, but it may damage the circuit.

⚠️ Attention: On some Almera N16 (especially after 2004) installed in the fuse box mini relay (smaller size). If you are purchasing a replacement relay, make sure it is the right size!

FAQ: Frequently asked questions about Nissan Almera N16 fuses

Which fuse is for the cigarette lighter?

The fuse is responsible for the cigarette lighter and 12V socket №5 face value 15A in the salon block. If after replacing it burns out again, check the connected devices (for example, a DVR or compressor) - they may consume too much current.

Why does the ECU fuse (No. 10) blow?

Most often this happens due to:

1. Short circuit in the wiring harness under the hood (check the insulation of the près sensors).
2. Malfunction of the oxygen sensor (lambda probe).
3. Problems with the generator (battery overcharged or undercharged).

If the fuse blows repeatedly, do not attempt to replace it - contact an auto electrician for diagnosis.

Where is the starter relay located?

Starter relay (K3) is located in the interior fuse box. It is responsible for supplying voltage to the starter when the key is turned. If the relay is bad, the starter will not turn, but you may hear a clicking sound when you try to start.

Is it possible to replace the fuse with a higher rating?

No! This is extremely dangerous. Fuses are rated for a certain current, and if you install a fuse with a higher rating, this can lead to:

• Melting of wire insulation.
• Fire in the cabin or under the hood.
• Failure of expensive components (for example, ECU).

If a fuse constantly blows, look for the cause - usually a short circuit or a faulty consumer.

How to check a fuse without a tester?

There are three ways:

1. Visual inspection: Hold the fuse up to a light - if the thread inside is broken, it is faulty.
2. Replacement method: Temporarily install a known-good fuse of the same rating from a different slot.
3. Checking the circuit: if the fuse heats up when you turn on a consumer (for example, headlights), it is faulty.
