Nissan Almera Classic (also known as B10 or N16 depending on the market) is a reliable sedan, but even it occasionally blows fuses. If your headlights, cigarette lighter or power windows are not working, the problem most likely lies in one of the fusible elements. In this article we will look at where the fuse boxes are located in Almera Classic, how to check and replace them, and also provide complete diagrams with an explanation of the purpose of each element.
A special feature of this model is that there are two main fuse blocks: one in the cabin (under the dashboard), the other in the engine compartment. However, their location and numbering may differ depending on the year of manufacture (2006–2012) and configuration. We have collected current data for all modifications, including restyled versions.
Where are the fuse boxes in Nissan Almera Classic?
B Almera Classic There are two main locations for installing fuses:
- 🔧 Salon block — located under the instrument panel on the driver's side. To access it, you need to unscrew two screws and remove the plastic cover.
- 🚗 Engine compartment block — located next to the battery, in a plastic box with a lid. Most often it is responsible for power circuits (generator, cooling fan, etc.).
Additionally, in some trim levels there may be third block — it is located behind the glove compartment and is responsible for the audio system and climate control (if installed). However, it is usually not present in basic versions.
Important: in Almera Classic after the 2010 release, the interior fuse box was moved closer to the steering wheel - its cover is now secured with latches rather than screws.

A complete diagram with photographs can be found in instruction manual (pages 8-12) or on the sticker under the unit cover. If you don't have a manual, download it in PDF from link (select model Almera Classic B10).
⚠️ Attention: Fuse F20 (7.5A, ECU) cannot be replaced with a higher rating - this may damage the electronic engine control unit. If it burns out frequently, look for the cause in the wiring or sensors.
Underhood fuse box: purpose and features
In the engine compartment Nissan Almera Classic there is a block with power fuses and relays. He is responsible for:
- ⚡ Main ignition relay
- 🔥 Generator and starter circuit fuses
- 💨 Radiator cooling fan
- 🔋Battery charging
The peculiarity of this block is the presence mini relay (for example, a fan or fuel pump relay), which can also fail. Checking them requires a multimeter or tester.
| Designation | Denomination (A) | Purpose |
|---|---|---|
| F30 | 30 | Electric cooling fan |
| F35 | 100 | Main ignition relay |
| R5 | — | Fuel pump relay |
To get to the engine compartment:
- Open the hood and locate the plastic box next to the battery.
- Press out the lid latches (they may be hidden under the rubber seal).
- Remove the cover and check the diagram on the inside.
⚠️ Attention: Fuse F35 (100A) responsible for the main power supply circuits. If it is burned out, the car will not start. Before replacing, check the condition of the battery and generator - often the reason lies in a short circuit or voltage surges.
☑️ Checking the engine compartment
How to check the fuse in Nissan Almera Classic?
Checking the fuse takes no more than 5 minutes. You will need:
- 🔦 Flashlight (to better see the state of the fusible thread)
- 🛠️ Tweezers or special forceps (usually included with the machine)
- 🔌 Multimeter (optional, for accurate diagnostics)
Step by step instructions:
- Turn off the ignition and disconnect the negative battery terminal (for safety).
- Remove the fuse box cover (in the passenger compartment or under the hood).
- Locate the faulty fuse using the diagram or visually (a blown thread will be broken).
- Remove the fuse with tweezers and inspect it. If the thread is intact, the problem is not there.
- For an accurate check, use a multimeter in dial mode: if the device does not beep, the fuse is blown.
If you don’t have a multimeter at hand, you can check the fuse by eye: hold it up to the light - if the thread inside is broken, the part must be replaced.
If the fuse blows immediately after replacement, do not install a new one - first find the cause of the short circuit. Most often, the problem is damaged wiring or a faulty consumer (for example, a window lift motor).
How to properly replace a fuse?
Replacing the fuse in Nissan Almera Classic - a simple procedure, but there are several nuances:
- Use only fuses of the same rating. Installing an element with a large amperage can lead to a fire in the wiring.
- If you don’t have the original fuse at hand, you can temporarily use a “bug” made of wire the same section, but only to get to the store!
- After replacement, check the operation of the circuit. If the fuse blows again, look for a short circuit.
Where to buy fuses for Almera Classic?
- 🛒 In any auto store (cost from 10 to 50 rubles per piece).
- 📦 In a set of fuses (for example, Bosch or Hella), where all the denominations are.
- 🚗 For disassembly (if you need a rare rating, for example, 80A for the main relay).
⚠️ Warning: Never replace a fuse with a coin, nail or thick wire - this may cause a fire in your vehicle. Even if “everything works,” the risk of wiring overheating remains.
If after replacing the fuse the problem remains (for example, the headlights do not work), check the relay in the same block - it could fail in parallel.
Common problems and their solutions
Owners Nissan Almera Classic often encounter typical faults related to fuses. Let's look at the most common cases:
- 🔌 Cigarette lighter doesn't work - check the fuse F10 (20A) in the salon block. If it is intact, the problem may be in the socket (contacts often oxidize).
- 💡 Headlights don't come on - fuses are to blame F5 (low beam) or F6 (high beam). Also check the light relay in the engine compartment.
- 🔊 The radio doesn't work - fuse F15 (10A) in the salon or F30 (15A) under the hood. If the fuses are intact, check the antenna amplifier.
- 🚪 Power windows don't work - fuse F25 (30A) and a relay in the cabin unit. Often the problem is in the motor or glass guides.
If fuses burn regularly, the reasons may be as follows:
- Short circuit in the wiring (for example, frayed wires under the seat).
- Faulty consumer (for example, a stove motor or fan).
- Poor contacts in the fuse box (oxidation or corrosion).
How to find a short circuit?
To find a short circuit, disconnect all consumers in the circuit and connect them one by one, observing the fuse. When it burns out, you have found the culprit. For accurate diagnostics, use a multimeter in resistance testing (continuity) mode.
Tips for caring for the fuse box
To keep the fuses in Nissan Almera Classic last longer, follow these recommendations:
- 🧹 Clean your contacts regularly block from dust and oxidation (use WD-40 or alcohol).
- 🔌 Don't overload the circuits — for example, do not connect powerful devices (compressor, refrigerator) to the cigarette lighter without an adapter.
- 🔧 Check the block fastening — vibrations can weaken contacts, which will lead to overheating.
- 📋 Keep a record of substitutions - if the same fuse lights up frequently, this is a signal of a malfunction.
Also useful to have in the car spare set of fuses different denominations - this will save time on the road. Store them in your glove compartment or glove compartment.
If you often drive off-road, it is recommended to treat the fuse box sealant or silicone grease - this will protect the contacts from moisture and corrosion.
FAQ: Frequently asked questions about fuses in Nissan Almera Classic
Is it possible to install a fuse of a higher rating if it constantly blows?
No! Installing a fuse with a large amperage can lead to overheating of the wiring and even a fire. If the fuse burns frequently, look for the cause - usually a short circuit or a faulty consumer (for example, a motor or lamp).
Where can I find a fuse diagram for my version of Almera Classic?
The diagram is usually printed on the inside of the block cover. If it is not there, download the instruction manual for your year of manufacture on the website Nissan Manuals or check the sticker on the back of the unit.
Why does the cigarette lighter still not work after replacing the fuse?
Possible reasons:
- The cigarette lighter socket contacts have oxidized (need to be cleaned).
- The relay in the block has burned out (check the relay K15 in the cabin block).
- The problem is in the wiring (the wire is frayed or melted).
Which fuse controls the alarm in Almera Classic?
The fuse is responsible for the alarm (if it is standard) F3 (10A) in the salon block. If the alarm is abnormal, the fuse may be located in its own block (usually under the dashboard or in the trunk).
