Nissan Almera G15 (2012-2019) is a popular sedan, but even it has occasional electrical problems. One of the most common malfunctions is the failure of the cigarette lighter or 12V socket. In 90% of cases, the fault is a blown fuse, not the outlet itself. However, finding it is not so easy: in Almera G15 fuses are scattered across two blocks, and the diagrams in the manual often do not coincide with reality.

This article will help you determine exactly where is the cigarette lighter fuse located in your car, will tell you its value and teach you how to replace it correctly. We will analyze all possible causes of burnout, show fuse block diagrams and give advice on how to avoid repeated breakdowns. And if you have already tried changing the fuse, but the cigarette lighter still does not work, here you will find an algorithm for diagnosing more serious problems.

Why does the cigarette lighter fuse blow in Nissan Almera G15

A fuse is the “weak link” in a circuit that protects the wiring from overloads. B Almera G15 it works for several reasons:

  • 🔌 Short circuit in the cigarette lighter socket (ingress of metal objects, liquids or oxidation of contacts).
  • 🔋 Excess load: connecting devices with current consumption >10A (for example, compressors, inverters or several gadgets through a splitter).
  • ⚡ Power surges in the on-board network (often happens when “lighting” from another car or a faulty generator).
  • 🔧 Poor quality fuse: Cheap Chinese analogues can burn out even under normal load.

The most insidious reason is oxidation of contacts in the fuse box. In this case, the new fuse may immediately blow out after replacement, since the resistance in the circuit is already increased. If you encounter such a problem, read the section on block diagnostics below.

Average cigarette lighter fuse life in Almera G15 — 2–3 years with active use. But if you often connect powerful devices (for example, DVR + navigator + laptop charger), the resource is reduced to several months.

Where is the cigarette lighter fuse: block diagram in Nissan Almera G15

B Nissan Almera G15 The cigarette lighter fuse can be located in one of two places:

  1. Main fuse box (in the cabin, to the left of the steering wheel under the panel).
  2. Additional block (in the engine compartment, next to the battery).

In most versions Almera G15 (2012–2019) The cigarette lighter fuse is located in salon, but its position depends on the year of manufacture and configuration. Below are the exact diagrams for different modifications.

💡

Before looking for a fuse turn off the ignition and remove the key from the lock. This will prevent short circuits when checking circuits.

Interior fuse box diagram

To access a block:

  1. Open the driver's door.
  2. Remove the cover under the steering wheel (it is secured with latches - pull it towards you).
  3. Find a plastic fuse box (usually gray or black).
Year of manufacture Fuse position Denomination (A) Notes
2012–2014 F30 (or F28) 15A On some models it may be designated as CIGAR or PWR OUTLET
2015–2017 F25 20A In configurations with two 12V sockets, there are also two fuses (F25 and F26)
2018–2019 F18 15A Can be combined with audio system fuse

If there is no diagram on the block cover, pay attention to the symbols on the fuse itself. The searched one is usually signed as CIG, ACC or POWER OUTLET. The color of the fuse will also indicate its rating:

  • 🟢 15A - green
  • 🟡 20A - yellow
  • 🔴 25A - red
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. A burnt out one will have a broken metal thread inside. You can also replace it with a known good one with the same rating (for example, from a size chain).

Additional block in the engine compartment

In rare cases (usually in cars with additional options, such as heated seats), the cigarette lighter fuse may be duplicated in the engine compartment. To find it:

  1. Open the hood and find the black plastic box next to the battery.
  2. Remove the cover (it is secured with latches).
  3. Look for a fuse marked F10 or F15 nominal 20–25A.
⚠️ Attention: If there is no fuse with this marking in the engine compartment, don't replace at random - this can lead to failure of other systems (for example, climate control).

How to properly replace the cigarette lighter fuse: step-by-step instructions

Replacing a fuse is a simple procedure, but there are nuances that will help you avoid mistakes. Follow this algorithm:

☑️ Preparing to replace the fuse

Done: 0 / 4

Step 1: Removing the Old Fuse

Use plastic tweezers (usually attached to the fuse box cover). If there is none, you can carefully pry the fuse with a small screwdriver or fingernail, but not metal objects - this may damage the contacts.

If the fuse is stuck and cannot be removed, do not force it. First, swing it left and right, and then pull it up. As a last resort, use pliers, but wrap them with electrical tape to avoid shorting adjacent contacts.

Step 2: Check the Circuit

Before installing a new fuse, check:

  • 🔍 Contacts in the block: They must be clean, without oxidation or carbon deposits. If necessary, clean them with an eraser or a special spray (for example, Kontakt 60).
  • 🔌 Cigarette lighter socket: Insert a 12V tester or light bulb to make sure the problem is the fuse and not the wiring.
  • 🚗 Mains voltage: with the ignition on, it should be 13.8–14.4V (checked with a multimeter at the battery terminals).

Step 3: Installing a New Fuse

Insert a fuse of the same rating as the old one. Never use bugs (wires or foil) - this may cause a fire! If a new fuse is not available, you can temporarily take one from a circuit that you can do without (for example, heated mirrors or glove compartment light), but don't forget to return it back.

After replacement, turn on the ignition and check the operation of the cigarette lighter. If the new fuse immediately blows, there is a short circuit in the circuit (read the section on diagnostics below).

💡

If the fuse blows again, do not replace it with a more powerful one (for example, 20A instead of 15A). This could burn the wiring or even cause a fire.

Diagnosis of faults: what to do if replacing the fuse does not help

If after replacing the fuse the cigarette lighter still does not work, the problem may be:

  1. The cigarette lighter socket itself (broken wires, oxidation of contacts).
  2. Wiring (frayed or broken wires under the panel).
  3. Relay (in some versions Almera G15 The cigarette lighter circuit is controlled by a relay K15).
  4. Fuse box (the tracks or contacts are burnt).

For diagnostics, you will need a multimeter or a test lamp. Follow this algorithm:

Checking the cigarette lighter socket

Disconnect the connector from the socket (usually it is attached to a latch under the panel) and check:

  • 🔋 Voltage on wires: when the ignition is on there should be 12V between + (usually red or yellow wire) and mass (black wire).
  • 🔌 Socket resistance: if it is close to 0 Ohm, there is a short circuit.

Wiring check

Inspect the wires leading from the socket to the fuse box. They often rub against metal parts of the body in the area of ​​the pedals or under the glove compartment. Please note:

  • 🔍 Isolation: If it is cracked or exposed, insulate the wires with heat shrink or electrical tape.
  • 🔥 Darkening or melting: This is a sign of a short circuit.
⚠️ Attention: If you find damaged wiring, do not twist the wires - use soldering or special terminal blocks. Twisting can cause a new short circuit.

Relay test

In some trim levels Almera G15 The cigarette lighter circuit is controlled by a relay K15 (located in the passenger compartment next to the fuses). To check it:

  1. Remove the relay and inspect its contacts for oxidation.
  2. Swap it with a known good relay (for example, K10 - fan relay).
  3. If after replacement the cigarette lighter works, buy a new relay.

How to avoid re-blowing a fuse: prevention

To make your cigarette lighter fuse last longer, follow these rules:

  • 🔌 Don't use power strips with a large number of devices. The maximum load per socket is 10A (120 W).
  • 🔋 Test devices before connecting. For example, some Chinese compressors consume up to 20A, which is guaranteed to blow the fuse.
  • 💧 Avoid contact with liquid into the nest. If you spill coffee or water, immediately turn off the fuse and dry the contacts with a hairdryer.
  • 🔧 Clean your contacts regularly socket and fuse box (once a year). Use a spray WD-40 Contact Cleaner or a regular eraser.

If you often connect powerful devices (for example, a refrigerator or inverter), install an additional 12V socket with a separate fuse. This will reduce the load on the standard chain and save you from problems.

💡

To connect energy-intensive devices (for example, a portable vacuum cleaner), use the socket in the trunk (if you have one). It usually has a separate fuse and is designed for heavy loads.

Common mistakes when replacing the cigarette lighter fuse

Even something as simple as replacing a fuse can be done incorrectly. Here are the most common mistakes and their consequences:

Error Consequences How to avoid
Using a fuse of a different rating Wiring burnout or device failure Always check the marking (15A or 20A)
Replacement with a “bug” (wire, foil) Fire or damage to electronics Use only standard fuses
Ignoring oxidized contacts New fuse blows quickly Clean contacts before replacing
Using metal extraction tools Short circuit in the unit Use plastic tweezers

Another common mistake is checking the fuse by eye. Sometimes the thread inside remains intact, but the fuse no longer conducts current due to microcracks. Always check it with a multimeter in continuity mode or replace it with a known good one.

FAQ: Answers to frequently asked questions

Is it possible to install a fuse of a higher rating (for example, 25A instead of 15A)?

No! This can lead to melted wiring or even a fire. The fuse is designed for the maximum load of the circuit. If it constantly burns out, look for the cause (short circuit or overload) rather than increase the rating.

The cigarette lighter works, but the fuse still blows. What's the matter?

Most likely the problem is periodic short circuit. This may happen due to:

  • Poor contact in the socket (for example, when the device plug is loose).
  • Damaged wire insulation, which sometimes shorts due to vibration.
  • A faulty device that you are connecting (for example, a charger with exposed contacts).

Check all connectors and wires for damage.

Where to buy a fuse for Nissan Almera G15?

Fuses of standard ratings (15A, 20A) are sold:

  • In any auto store (cost: 20–50 rubles).
  • In the auto parts department of hypermarkets (Leroy Merlin, Obi).
  • On Aliexpress (but you will have to wait a long time).

For Almera G15 suitable type fuses ATO/ATC (standard size). Take a pack of 10 pieces - they will come in handy often.

Is it possible to change the cigarette lighter socket yourself if it is burnt out?

Yes, it's not difficult. You will need:

  1. New socket (item no. for Almera G15 — 285B0-3CA0A or analogues).
  2. Screwdriver and pliers.
  3. Heat shrink tubing or electrical tape.

Disconnect the negative terminal of the battery, remove the tunnel lining, disconnect the connector from the old socket and connect the new one. The main thing is not to confuse the polarity (+ usually red wire – black).

Why in mine Almera G15 two 12V sockets, but only one works?

In some trim levels Almera G15 (For example, Tekna) two sockets were installed: one in the tunnel, the other in the trunk or armrest. They may have different fuses:

  • Main socket - F25 (20A).
  • Additional - F26 (15A) or F30.

Check both fuses. It is also possible that the second socket is not connected to the on-board network (this happens in basic configurations).
