Nissan Micra is a compact hatchback that is valued for its efficiency and reliability, but even in such a car, electrical circuits sometimes fail. The reason for this is most often fuses - small but critical elements that protect the on-board network from overloads. If your headlights, windshield wipers or radio stop working, the first thing you should check is fuse box.
In this article we will look at where the fuse box is located in Micra different generations (including popular K13 And K14), how to remove it correctly, decipher the circuits and learn to distinguish a blown fuse from a working one. You will also learn what replacement errors can lead to a short circuit, and how to avoid common problems when repairing car electronics.
Where is the fuse box located in Nissan Micra?
Depending on the year of manufacture and configuration Micra may have one or two 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 (it is usually secured with latches).
- ⚡ Additional relay block - in some versions (for example, K13 with engine
HR16DE) is located in the engine compartment, next to the battery.
In models Micra after 2017 (including K14) the main fuse box is often moved to a more convenient location - under the glove compartment or behind the decorative panel to the left of the steering wheel. The exact location depends on the supply market (European, Japanese or Russian assembly).
- Under the instrument panel
- Under the glove compartment
- In the engine compartment
- I don't know, I haven't looked yet
If you can't find the block, please take a look at instruction manual your model - there should be a diagram indicating the exact location. As a last resort, you can use a flashlight and inspect the space under the steering wheel: the block cover usually has the inscription FUSE or fuse pictogram.
Fuse diagram and decoding Nissan Micra K13/K14
Each fuse in the block is responsible for a specific electrical circuit. Below is a typical diagram for Micra K13 (2010–2017) and K14 (2017–present). Please note that depending on the configuration, some chains may be missing or have a different number.
| Fuse number | Current (A) | Purpose of the circuit | Symptoms of a problem |
|---|---|---|---|
F1 |
10 | Side light bulbs (left side) | Left side lights or dashboard lights do not light up |
F7 |
15 | Windshield wipers, windshield washer | Wipers do not work or fluid does not splash |
F10 |
20 | Cigarette lighter, 12V socket | Phone charging or connected devices do not work |
F15 |
10 | Engine control unit (ECU) | Startup problems, error P0600 on diagnostics |
F20 |
30 | Heated rear window | The rear window does not heat, the filaments are broken |
A complete diagram for your model can be found in service documentation or on the cover of the fuse box (the decoding is often marked there). If you have Micra with diesel engine (K9K), pay attention to the fuses F25 And F26 — they are responsible for the fuel pump and glow plugs.
How to check a fuse without a tester?
If you don’t have a multimeter at hand, you can visually inspect the fuse through the light - a burnt one will have a broken metal thread inside. You can also replace a suspicious fuse with a known good one with the same rating (for example, from the cigarette lighter circuit).
Causes of blown fuses and how to avoid them
Fuses don't just blow - their blown is always associated with a problem in the electrical circuit. Here are the most common reasons:
- ⚡ Short circuit - the most dangerous situation is when the positive wire touches ground. Often occurs due to frayed insulation or moisture ingress.
- 🔌 Circuit overload — connecting powerful devices (for example, a compressor or inverter) to the cigarette lighter without an additional relay.
- 🚗 Consumer fault - for example, a jammed windshield wiper motor or a broken headlight bulb.
- 🔧 Installation errors - using a fuse with the wrong rating (for example, 30A instead of 10A).
B Nissan Micra K13 most often the fuses of the cigarette lighter circuits burn (F10) and heated rear window (F20). The first is due to the connection of non-standard gadgets, and the second is due to the breakage of the filaments on the glass.
⚠️ Attention: If the fuse burns again after replacement, don't increase its value - this may cause a fire! It is necessary to look for the cause of the short circuit or overload.
To extend the life of fuses, monitor the condition of the wiring, do not connect devices with a power of more than 120 W to the cigarette lighter, and regularly check the contacts for oxidation. In wet weather, pay special attention to the door seals - water entering the interior can cause a short circuit in the fuse box.
Step-by-step instructions for replacing the fuse
Replace the fuse in Nissan Micra you can do it yourself, without resorting to the help of a car service. You will need:
- 🔧 Tweezers (usually included with the machine or on the unit cover).
- 🔦 Flashlight (for illuminating the block).
- 📋 New fuse same denomination.
Algorithm of actions:
- Turn off the ignition and remove the negative terminal from the battery (this is mandatory for safety!).
- Locate the fuse box and remove the cover (it is usually secured with latches or a screw).
- Using tweezers, remove the burnt fuse. Pay attention to its color and markings - they correspond to the current strength (for example, red = 10A, blue = 15A).
- Install a new fuse same denomination. Never use wire bugs!
- Check the operation of the circuit. If the fuse blows again, look for the cause (short circuit or faulty consumer).

If after replacement the fuse blows again, it is necessary to diagnose the circuit. To do this, you can use a multimeter in dialing mode or contact a car service. B Micra with the system Nissan Intelligent Key pay special attention to the fuse F22 (10A) - he is responsible for the operation of the immobilizer.
Common mistakes when working with the fuse box
Even experienced car owners sometimes make mistakes that can lead to serious damage. That's what can't do when replacing fuses in Nissan Micra:
- 🔥 Install a fuse with large denomination - this may cause melted wiring or a fire.
- 🛠 Using a wire or foil (“bug”) instead of a fuse is a direct path to a short circuit.
- 💡 Neglect checking the circuit after it burns out again - if the problem is not fixed, the new fuse will burn out just as quickly.
- 🔋 Do not remove the terminal from the battery - when working with the fuse box, there is always a risk of a short circuit.
Another common mistake is confusing fuses and relays. Relays look like small boxes with legs and are responsible for turning on powerful consumers (for example, a radiator fan or headlights). Replacing them requires greater care, since incorrect installation can damage the control electronics.
⚠️ Attention: B Nissan Micra K14 with the system ProPILOT Some fuses are related to the operation of sensors and cameras. Replacing them without diagnostics may lead to failure of the driver assistance systems.
If you are not confident in your abilities, it is better to turn to professionals. For example, replacing a fuse in a circuit ECU (F15) requires subsequent adaptation of the control unit, which cannot be done without diagnostic equipment.
Diagnosis of faults based on symptoms
If you don't know which fuse to check, rely on the symptoms of the malfunction. Below are typical signs and corresponding chains in Nissan Micra:
| Symptom | Possible fuse | Additional checks |
|---|---|---|
| Low beam headlights do not work | F3 (10A) or F4 (10A) |
Check lamps and relays R1 |
| Heater fan does not turn on | F12 (30A) |
Inspect the heater motor for jamming |
| Central locking doesn't work | F18 (10A) |
Check the door actuators and the wiring in the corrugation between the door and the body |
| The phone does not charge in the cigarette lighter | F10 (20A) |
Inspect the 12V outlet for melting |
If the symptoms do not match any of the circuits, the problem may lie in the relay or damaged wiring. In this case, only a complete diagnosis using wiring diagrams for Micra.
Before replacing the fuse in the lighting circuit, check the lamps - often the reason lies in their burnout, and not in the fuse.
