Introduction: Why do you need a fuse diagram Nissan Almera Classic

Electrical system Nissan Almera Classic (also known as Nissan Sunny N16 in some markets) is built around two main fuse and relay blocks. Without knowing their location and purpose, even a simple light bulb replacement or fault diagnosis can turn into an hour-long quest. Fuses protect circuits from overloads, and relays control high-current consumers - from headlights to cooling fans.

In this article you will find detailed diagrams of both blocks (interior and engine compartment), decoding of each fuse and relay indicating the current strength, as well as practical diagnostic tips. We took into account the features of different years of production (2006–2012) and configurations so that the information was as accurate as possible. If your Almera Classic the headlights suddenly lost their light, the stove stopped working or the central locking did not work - here you will find the answer to where to start checking.

Where are the fuse and relay boxes located? Nissan Almera Classic

B Almera Classic There are two main blocks:

  • 🔧 Salon block — located to the left of the steering column, under the instrument panel. To gain access, you need to open the cover by prying it with a flat-head screwdriver or your finger into a special groove.
  • 🚗 Engine compartment block — located next to the battery, in a plastic box with a lid. On some modifications, the box may be hidden under a decorative overlay.

The photo below shows both blocks (click to enlarge). Please note: on right-hand drive vehicles (for example, for the Japanese market), the location of the interior unit may be mirror different.

Important: before working with fuses Be sure to remove the negative terminal from the batteryto avoid short circuit. If you are testing a live circuit (for example, looking for a current leak), use multimeter in voltage test mode (DC 20V).

Interior fuse box diagram Nissan Almera Classic

The cabin unit contains fuses responsible for most consumers: lighting, instrument panel, audio system, etc. Below is a table with a breakdown of each fuse (the numbers correspond to the designations on the block cover).

Fuse no. Current (A) Purpose Notes
1 10 Side light bulbs (left side) Also protects the license plate light
5 7.5 Engine control unit (ECU) Do not replace with a fuse of a higher rating - this will lead to ECU failure!
10 15 Cigarette lighter Often fails when using powerful devices (for example, car vacuum cleaners)
15 20 Heater fan If the fuse burns out repeatedly, check the heater motor for jamming
20 10 Central locking, immobilizer If there is a malfunction, also check relay K1 in the same block

A complete diagram of the cabin unit in high resolution is available download here. Please note: on vehicles with air conditioning there is an additional relay in the block K7, responsible for the compressor. Its absence on the diagram does not mean a malfunction - it’s just that your equipment does not provide climate control.

⚠️ Attention: fuse No.5 (7.5A) responsible for nutrition ECU. If it burns out, the engine will not start and the indicator will light up on the dashboard. CHECK ENGINE. Under no circumstances install a bug instead - this may damage the electronic control unit.

Diagram of the engine compartment fuse and relay box

Engine compartment block Nissan Almera Classic contains fuses and relays for high-current circuits: starter, generator, injection system, headlights, etc. Its location depends on the year of manufacture:

  • 🔋 2006–2008 — the unit is located directly on the battery, under a plastic cover.
  • 🔌 2009–2012 — the unit has been moved to the left side of the engine compartment (driver’s side), next to the washer reservoir.

Below are the key fuses and relays of the engine compartment unit:

Designation Type Denomination Purpose
A fuse 80A Generator main fuse
B fuse 60A ABS power supply circuit
K1 Relay — Fuel pump relay
K3 Relay — Cooling Fan Relay (Low Speed)
K5 Relay — Starter relay

If your Almera Classic won't start, first check the fuse A (80A) and relay K5. A common cause of starter failure is oxidation of the relay contacts - they can be cleaned WD-40 or fine sandpaper.

How to check and replace a fuse or relay

To check the fuses you will need multimeter or a simple 12V test lamp. Algorithm of actions:

  1. Disconnect the negative terminal of the battery.
  2. Remove the fuse with special pliers (usually attached to the block cover) or tweezers.
  3. Inspect the fuse for burnt thread (if the case is transparent) or check the resistance with a multimeter (should be close to 0 ohms).
  4. Install a new fuse same denomination. Using a high current fuse may cause a fire in the wiring!

To check the relay:

  • 🔊 Listen to whether the relay clicks when the corresponding circuit is activated (for example, when the headlights are turned on). No click indicates a malfunction.
  • 🔧 Measure the resistance of the relay winding with a multimeter (should be between 50-120 Ohms).
  • 🔄 Swap the suspicious relay with a known good one (for example, the fan relay and starter relay are often interchangeable).
⚠️ Attention: If a new fuse blows immediately after installation, this indicates short circuit in the circuit. Do not reinstall the fuse - first find and eliminate the cause of the short circuit, otherwise you risk burning the wiring.
💡

If you don't have a multimeter at hand, you can check the fuse by eye - hold it up to the light. A burnt filament will be visible as a break in the metal strip inside the housing.

Common problems and their solutions

Owners Nissan Almera Classic often encounter typical faults related to fuses and relays. Here are the most common cases and ways to eliminate them:

  • 💡 Headlights or tail lights do not work - check the fuses No. 1 (10A) And No. 2 (10A) in the cabin unit, as well as a relay K2 in the engine compartment. Often the problem lies in oxidized contacts of lamps or steering column switch.
  • 🔊 The sound signal does not work - the fuse is at fault No. 12 (10A) or relay K4. Also check the contacts on the steering wheel and the horn button.
  • 🚗 The car does not start, the starter does not turn - check sequentially:
    • fuse A (80A) in the engine compartment.
    • Relay K5 (starter) - when turning the key it should click.
    • Contacts on the starter solenoid relay (often oxidize).
  • ❄️ Furnace or air conditioner not working - check the fuse No. 15 (20A) and relay K7 (if any). If the heater fan does not turn on at all speeds, the problem may be with the heater motor resistor.

If the problem persists after replacing the fuse, the cause may be a malfunction of the consumer itself (for example, a short circuit in the fan motor) or a broken wiring. In this case, it is recommended to contact electrician with diagnostic equipment.

What to do if the cigarette lighter fuse blows every time?

This is a typical problem when using powerful devices (for example, car refrigerators or compressors). Solutions:

1. Connect the device directly to the battery via the fused connector.

2. Install an additional fuse block with a separate power line from the battery.

3. Check the cigarette lighter itself - often a short circuit occurs inside it due to metal objects or contact melting.

Where to buy fuses and relays for Nissan Almera Classic

Fuses and relays for Almera Classic are not in short supply, but it is important to choose quality spare parts. Here's where you can buy them:

  • 🛒 Official Nissan dealers - original fuses and relays (see article numbers below), but the price may be too high.
  • 🔧 Auto stores (For example, Avtodelo, existential, ATL) - a wide range of analogues from Bosch, Hella or Valeo.
  • 🌍 Online platforms:
    • AliExpress - budget fuse sets (but quality may vary).
    • AutoPro or Drome - verified sellers with a guarantee.

Article numbers of original spare parts for ordering:

  • Fuses: 28510-JA00A (set of mini fuses).
  • Relay: 25230-4M200 (standard 4-pin relay).

When purchasing, pay attention to rated current And fuse type (mini, maxi, knife). For example, the cigarette lighter needs a fuse for 15A type mini blade.

💡

Never use bugs (homemade jumper wires) instead of fuses - this may cause a fire in the car. Even temporary replacement should only be made with a fuse of the correct rating.

FAQ: Frequently asked questions about fuses Nissan Almera Classic

Can fuses from other cars be used in Almera Classic?

Yes, if they match type (For example, mini blade) and rated current. Fuses of standard sizes (mini, maxi, normal) are universal for most cars. The main thing is not to exceed the nominal value indicated in the diagram.

Why does it blow again after replacing the fuse?

This indicates short circuit in the chain. Common reasons:

  • Damaged wire insulation (for example, rubbed against the body).
  • Faulty consumer (for example, a fan motor with a stuck bearing).
  • Poor contacts in connectors (oxidation or burning).

It is necessary to “ring” the circuit with a multimeter in resistance testing mode to find the location of the short circuit.

Which fuse is responsible for the radio in Almera Classic?

The fuse controls the audio system No. 11 (10A) in the salon block. If after replacing it the radio does not work, also check:

  • The fuse is in the radio itself (usually located on the rear panel).
  • Wiring for a break (especially if the radio was installed abnormally).

Where is the fuel pump relay located?

Fuel pump relay (K1) located in engine compartment. On some modifications it may be duplicated in the interior unit (check the diagram on the lid). If the fuel pump does not pump fuel, also check:

  • fuse No.5 (7.5A) in the cabin unit (ECU power supply).
  • Ground on the fuel pump (often oxidizes).

Can I change the entire fuse box myself?

Technically yes, but it is a labor-intensive process requiring:

  • Disconnecting the battery and removing the panel (for the interior unit).
  • Resoldering or reconnecting all wires (risk of error is high).
  • Check all circuits after replacement.

If the unit is damaged (for example, melted), it is better to contact service. Cost of a new fuse box for Almera Classic - about 3–5 thousand rubles.
