Fuse box Nissan Almera Classic (also known as Nissan Sunny B15 in some regions) is a key element of the vehicle's electrical system that protects circuits from overloads and short circuits. Many owners are faced with the need to replace fuses when electrical appliances fail, from headlights to power windows, but they do not always know where to look for the unit and how to properly service it.

In this article you will find detailed fuse diagrams for different years of manufacture Almera Classic (2006–2012), a description of their purpose, as well as step-by-step instructions for diagnosis and replacement. We will also look into typical causes of blown fuses and give advice on how to avoid repeated breakdowns. If your Nissan suddenly stopped responding to the turn signals or the heater is not working - here you will find the answers.

Where is the fuse box located on Nissan Almera Classic?

B Almera Classic There are two main fuse blocks:

  • 🔧 Main unit — located in the cabin, under the instrument panel on the driver’s side. To access it, you need to open the cover, which is secured with latches.
  • ⚡ Additional relay block — located in the engine compartment, next to the battery (on some modifications it can be hidden under a plastic cover).

The exact location may vary slightly depending on the year of manufacture and equipment. For example, in models 2006–2008, the main unit is often hidden behind the glove compartment, and in restyled versions (2009–2012) it was moved closer to the steering wheel. Be sure to turn off the ignition before searching. - this will prevent a short circuit if the contacts accidentally touch.

F10 10 Front fog lights PTF lights don't light up, switch stops working
F15 20 Power windows Windows don't go up/down
F20 10 Audio system, navigation The radio does not turn on, there is no sound

The complete diagram for your modification can be found in service documentation or on a sticker under the unit cover. Please note: on some versions Almera Classic with K9K diesel engine the circuit may differ - for example, a fuse F25 (15A) responsible for glow plugs.

💡

If the fuse blows again after replacement, do not rush to install a more powerful one - this may lead to fire in the wiring. First check the circuit for short circuit!

How to check and replace a fuse: step-by-step instructions

Replacing the fuse with Nissan Almera Classic - a simple procedure, but requires care. Here's what you'll need:

  • 🔦 Flashlight (for illuminating the block).
  • 🛠️ Tweezers or a special puller (often included with the machine).
  • 🔋 A set of spare fuses (preferably of different ratings).
  • 📸 Tester or multimeter (for checking the circuit).

Algorithm of actions:

  1. Turn off the power. Remove the negative terminal from the battery or turn off the ignition (if the fuse is not connected to circuits that remain energized).
  2. Remove the unit cover. Press the latches or remove the screws (depending on the unit model).
  3. Locate the blown fuse. Usually he has melted body or broken thread inside. If it is not visually visible, use the tester in dial-up mode.
  4. Remove and replace. Carefully pry the fuse with tweezers and insert a new one. same denomination.
  5. Check your work. Connect the battery and turn on the ignition. Verify that the problem is resolved.
What should I do if the fuse burns out immediately after replacement?

This indicates short circuit in the circuit. Required:

1. Disconnect all consumers connected to this circuit (for example, a radio or PTF).

2. Check the wiring for a short to ground.

3. Check the relay connected to this circuit - it could also be faulty.

If the problem persists, have an auto electrician diagnose the wiring.

Typical causes of blown fuses

Fuses in Nissan Almera Classic They rarely fail just like that. Most often this is due to:

  • ⚡ Short circuit - the most common reason. Occurs due to damage to wire insulation, oxidation of contacts, or malfunction of consumers (for example, a window lift motor).
  • 🔥 Circuit overload. For example, if you connect a too powerful device (compressor, inverter) to the cigarette lighter, the fuse F7 (15A) may not stand it.
  • 💡 Relay failure. Relays and fuses often work in pairs. If the relay is stuck closed, the fuse will blow.
  • 🚗 Bad contact. Oxidized or loose terminals create additional resistance, which leads to heating and burnout.

The most "problematic" fuses in Almera Classic:

  • 🔋 F7 (cigarette lighter) — often fails due to the connection of powerful gadgets.
  • 💡 F10 (fog lights) — burns out when moisture gets into the headlights or a short circuit in the power button.
  • 🔊 F20 (audio system) — suffers from non-standard radios with incorrect connections.
💡

If the fuse blows immediately after replacement, don't increase its value - this may lead to melted wiring or fire. Look for the cause in the circuit!

Common mistakes when working with fuses

Even experienced car owners sometimes make mistakes that can lead to serious damage. That's what can't do:

⚠️ Attention: Never use "bugs" (homemade jumpers made of foil or wire) instead of fuses! This may cause wiring fire and even a car fire.
  • 🔧 Installing a higher rated fuse. For example, instead of 10A put 15A. This will not solve the problem, but will only increase the risk of equipment damage.
  • 🔍 Ignoring the cause of burnout. If you simply replace the fuse without eliminating the short circuit, it will burn out again.
  • 🛠️ Using non-original fuses. Cheap Chinese analogues may have an inaccurate value or poor contact.

Another common mistake is checking the fuse by eye. Sometimes the thread inside remains intact, but the fuse is already faulty. Always use a multimeter in continuity mode or a tester.

How to extend the life of fuses?

To keep the fuses in Nissan Almera Classic last longer, follow these tips:

  • 🔌 Do not overload the circuits. Do not connect devices with a power of more than 120 W (for example, car refrigerators or powerful compressors) to the cigarette lighter.
  • 💧 Keep an eye on the humidity. Water entering the fuse box (for example, after washing) can cause corrosion of the contacts.
  • 🔧 Check your contacts regularly. Oxidized or loose terminals increase resistance and heat.
  • 🚗 Use quality fuses. Give preference to brands Hella, Bosch or original Nissan.

If you frequently experience blown fuses, it makes sense carry out a complete diagnostic of the electrical system. Pay special attention to:

  • 🔋 Battery and generator — Voltage surges can damage fuses.
  • 🔌 Wiring - look for abrasions, exposed wires, especially in bend areas (for example, near doors).
  • ⚡ Relay - A faulty relay can cause an overload in the circuit.

FAQ: Frequently asked questions about fuses Nissan Almera Classic

🔧 Which fuse is responsible for the low beam headlights?

For low beam Almera Classic fuse responds F11 (10A) (left headlight) and F12 (10A) (right headlight). If only one fuse blows, check the lamp and the associated headlight wiring for a short circuit.

⚡ Why does the cigarette lighter fuse burn out when the navigator is connected?

This happens due to exceeding permissible power. Cigarette lighter in Almera Classic designed for 12V/10A (120 W). If your navigator or charger draws more (for example, 180 W), the fuse F7 (15A) will burn out. Solution: Use a power strip with a separate fuse or connect the device directly to the battery via a fuse.

🚗 Is it possible to drive without a fuse if it is burned out?

No! The fuse protects the circuit from overload. If it is removed there is a risk reflow wiring or failure of expensive components (for example, the engine control unit) increases sharply. As a last resort, you can temporarily install a fuse on lower denomination (for example, instead of 15A put 10A), but only to get to the workshop.

🔋 Where to buy original fuses for Nissan Almera Classic?

Original fuses Nissan can be found:

  • In official dealer centers (article: 28500-JD00A for dialing).
  • Auto parts stores (eg. Exist.ru, Autodoc).
  • From verified sellers on Avito or Yandex.Market (pay attention to reviews).

An alternative is high-quality analogues from Hella or Bosch.

💡 How can you tell if a relay has burned out and not a fuse?

If the problem remains after replacing the fuse, check the relay:

  1. Remove the relay from the block and inspect it for melting or damage to the housing.
  2. Test the relay coil with a multimeter - the resistance should be within 50–120 Ohm.
  3. Check the relay contacts for oxidation or burning.

Typical “symptoms” of a faulty relay: clicks without operation, periodic shutdown of equipment (for example, a stove fan).
