Nissan Micra K11 (1992–2002) is a compact and reliable hatchback, but even it has electrical problems over time. Most often the culprit is the burnt out. fuses, which protect circuits from short circuits and overloads. If your headlights, cigarette lighter or power windows do not work, the first thing you should check is them.
In this article you will find detailed fuse layout diagram for Micra K11, a table with denominations, step-by-step instructions for replacement and tips on how to avoid common mistakes. We'll also look at which fuses blow most often and why, so you can prevent further failures.
Where are the fuses located in Nissan Micra K11
B Micra K11 fuses are located in two main blocks:
- 🔧 Main fuse box — located to the left of the steering column, under the instrument panel. To gain access, you need to open the cover (it is secured with latches).
- 🔋 Relay and fuse box — located in the engine compartment, next to the battery (under the plastic cover). High power fuses are located here (for example for the cooling fan).
There is usually a diagram with symbols on the cover of the main unit, but over time it wears off. If you don't have the original sticker, use table below — it is relevant for all modifications K11 (including restyled versions 1998–2002).
Important: some trim levels (for example, with air conditioning or power accessories) may have additional fuses. If you don't find what you need, check service book or a diagram on the back of the block cover.
Fuse diagram and decoding Nissan Micra K11
Below is a table with ratings and assignments of fuses for Micra K11. Please note: the color of the fuse depends on its current strength (for example, 10A - red, 15A - blue, 20A - yellow).
| Number | Denomination (A) | Purpose | Notes |
|---|---|---|---|
| 1 | 10 | Side light bulbs (left side) | Often burns out when installing LEDs |
| 5 | 15 | Cigarette lighter | Lights up when connecting powerful devices (for example, a compressor) |
| 10 | 20 | Window lifters | May burn out if the glass freezes or the motor malfunctions |
| 15 | 10 | Engine control unit (ECU) | It is forbidden to replace it with a fuse of a higher rating - this may damage the ECU! |
| 20 | 30 | Radiator cooling fan | Located in the block under the hood |
The complete diagram can be found in repair manual (for example, in the manual Nissan Micra K11 Service Manual). If you do not have a paper version, download PDF instructions from thematic forums (for example, Micra Club Russia).

How to check the fuse in Micra K11: step by step instructions
Checking the fuse takes no more than 5 minutes. You will need:
- 🔦 Flashlight (to see the block better).
- 🛠️ Tweezers or a special puller (usually included with the machine).
- 🔍 Magnifying glass (optional, for inspecting small parts).
Algorithm of actions:
- Turn off the ignition and remove the negative terminal from the battery (this is mandatory for safety!).
- Open the fuse box cover (it is secured with latches or one screw).
- Find the required fuse according to the diagram (see table above) and remove it with tweezers.
- Inspect the fuse for light: if the jumper inside is burnt out - it is faulty. You can also check with a multimeter in dial mode.
☑️ Checking the fuse
If the fuse is intact, but the problem remains, check relay (they are in the same block) or wiring. For example, if the headlights do not work, but fuse No. 1 is working, the contacts in the block may have oxidized or the lamp has burned out.
⚠️ Attention! Never replace a fuse with a "bug" (wire or foil). This may lead to fire in the wiring or failure of expensive components (for example, an ECU or a generator).
Typical problems and why fuses blow
B Nissan Micra K11 The most common fuses that fail are:
- 💡 No. 1 and No. 2 (dimensions) - due to the installation of LED lamps without resistors or corrosion in the sockets.
- 🔌 No. 5 (cigarette lighter) - when connecting powerful devices (vacuum cleaner, compressor) or a short circuit in the socket.
- 🪟 No. 10 (window lifters) - if the windows freeze or the lift motor is worn out.
- 🚗 No. 15 (ECU) - in case of voltage surges or generator malfunction.
The main reasons for burnout:
- Short circuit - for example, due to damaged wire insulation or moisture getting into the connectors.
- Circuit overload — when connecting devices with a current higher than the fuse rating (for example, a 12V→220V inverter to a cigarette lighter).
- Consumer fault — if the window lift motor or cooling fan begins to “eat” more current.
If the fuse lights up again after replacement - You can’t just install a new one! You need to look for the reason: test the circuit with a multimeter, check the consumers and wiring. For example, if the cigarette lighter fuse constantly blows, most likely the problem is in the socket (oxidation or short circuit).
What should I do if fuse No. 15 (ECU) blows again?
This is a serious malfunction! Possible reasons:
- Generator malfunction (battery overcharge).
- Short circuit in the ECU wiring harness.
- Problems with the engine mass.
In this case, you need to go for diagnostics - independent repairs can aggravate the problem.
How to replace a fuse correctly: expert advice
Replacing the fuse seems simple, but there are nuances that will help you avoid mistakes:
- 🔧 Use only fuses original denomination. For example, if 10A has burned out, you cannot set 15A or 20A - this will damage the circuit.
- 🔍 Before replacing, inspect the fuse socket: if the contacts are oxidized or burnt, clean them with fine sandpaper.
- 📋 Keep a record of the replacement. If the same fuse blows more than 2-3 times a year, look for the cause (see section above).
Step by step instructions:
- Buy a set of fuses (eg Hella or Bosch) - they are more reliable than their Chinese counterparts.
- Remove the faulty fuse with tweezers.
- Install the new one, making sure it fits tightly into the socket.
- Close the unit cover and check the operation of the circuit.
If after replacement the fuse blows again - do not repeat the procedure! This is a signal of a serious malfunction. For example, if the cooling fan fuse is blowing, the fan motor may be stuck or the winding may be shorted.
Keep spare fuses in the glove compartment. Optimal set: 2–3 pieces of 10A, 15A and 20A ratings. This will save time on the road.
Where to buy fuses for Nissan Micra K11: prices and manufacturers
Fuses for Micra K11 — a consumable, but it’s better not to skimp on quality. Here's where you can buy them:
| Place of purchase | Cost (for 1 piece) | Pros | Cons |
|---|---|---|---|
| Auto stores (Avtodelo, existential) | 10–30 ₽ | Can be checked visually, consultation with the seller | Prices are higher than online |
| Online (Wildberries, Ozon, AliExpress) | 5–20 ₽ | Cheaper, large selection | Risk of running into a fake, long delivery |
| Showdown (Nissan) | 5–15 ₽ | Original fuses | You have to go yourself, limited selection |
Recommended brands:
- 🏆 Hella - German quality, reliable contacts.
- 🥈 Bosch — good price/quality balance.
- 💰 NoName (Chinese) - cheap, but can fail at a crucial moment.
Advice: buy fuses from sealed blister - this is a guarantee that they are new and not oxidized. Avoid market stalls where goods are stored in open boxes (there is high humidity and the contacts can corrode).
Frequently asked questions about fuses Nissan Micra K11
Can fuses from other cars be used?
Yes, if they match denomination and type (in Micra K11 standard blade fuses are used ATO/ATC). The main thing is not to exceed the original denomination. For example, fuses Toyota or VW will be suitable if they are designed for the same current.
Why does the cigarette lighter not work after replacing the fuse?
Possible reasons:
- The coil in the cigarette lighter itself has burned out (needs to be disassembled and checked).
- The contacts in the socket have oxidized (clean them with sandpaper).
- The problem is in the wiring (check the circuit with a multimeter).
Which fuse controls the low beam?
B Micra K11 fuses are responsible for the low beam No. 3 and No. 4 (10A) - separately for left and right headlights. If only one burns out, also check the lamp and the connector in the headlight.
What to do if the fuse is circuited, but it looks intact?
This happens when microcracks in the jumper. Test the fuse with a multimeter in test mode. If the resistance is infinite, it is faulty, even if it visually looks normal.
Is it possible to drive without a fuse if it burns frequently?
Absolutely not! This is tantamount to driving without insurance - if there is a short circuit, the wiring or control unit may burn out. It is better to temporarily turn off the problematic consumer (for example, do not use the cigarette lighter) and start looking for the cause.
If the fuse blows again, this is not a “defect”, but a signal of a malfunction in the circuit. Ignoring the problem may result in costly repairs (such as replacing the ECU or wiring harness).
