Nissan Bluebird Sylphy - a popular sedan, known for its reliability, but even in it fuses periodically blow. If your headlights, power windows or radio are not working, the first priority is to check fuse blocks and relay. In this article, we will look at where they are, how to replace them correctly, and what mistakes owners most often make.
Models Sylphy different generations (including restyled versions for Russia and China) have similar schemes, but there are nuances. For example, in cars with 2.0 MR20DD engine, the fuse box under the hood may differ from versions with 1.6 HR16DE. We have collected current data for all modifications 2012–2026, including hybrid options.
Where are the fuse boxes in the Nissan Bluebird Sylphy?
B Nissan Bluebird Sylphy There are two main fuse blocks:
- 🔧 Salon block — located to the left of the steering column, behind the plastic cover. Access to it opens when the driver's door is open.
- 🚗 Engine compartment block — located next to the battery (in right-hand drive models - on the right, in left-hand drive models - on the left). The block cover is usually black with the inscription
FUSE. - ⚡ Additional relay block — in some trim levels it is installed under the glove compartment or behind the glove box.
In hybrid versions (for example, Sylphy e-Power) there may be a third block - next to the inverter. Its fuses are responsible for high-voltage circuits, and independently interfere with them not recommended without special training.
- In the salon block
- In the engine compartment
- In the relay block
- I don't know, haven't checked
To get to the cabin unit, you will need:
- Open the driver's door and move the seat back.
- Press the latch of the unit cover (it is located at the bottom of the panel).
- Gently pull the cover towards you - it will be removed from the guides.
⚠️ Attention: In 2020+ models, the block cover can be secured with an additional screw for a Phillips screwdriver. Do not try to rip it off - this will lead to breakage of the latches.
Decoding the fuses of the cabin unit
The cabin unit contains fuses responsible for lighting, electronics and comfort. Below is a table for the most common modifications (including Sylphy G11 And G12).
| Number | Ampere | Purpose | Notes |
|---|---|---|---|
| 1 | 10A | Audio system, navigation | Also responsible for the USB port |
| 5 | 15A | Cigarette lighter | Often burns out when using powerful devices |
| 10 | 7.5A | ABS sensors | If there is a malfunction, it lights up ABS on the dashboard |
| 14 | 10A | Window lifters | If all the windows do not work, check the relay K12 |
| 20 | 15A | Low beam (left headlight) | In right-hand drive models it may be mirrored |
The complete diagram for your modification can be found in instruction manual (section 8-30 for Sylphy 2018–2023). If you don’t have a manual at hand, use online catalogs like Nissan TechInfo (registration required).
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 - the blown thread will be broken. You can also replace a suspicious fuse with a known working fuse of the same rating (for example, from the cigarette lighter circuit).
Pay attention to the fuse #25 (10A) - he is responsible for immobilizer. If it burns out, the car may not start and the key light on the dashboard will come on. In this case:
- 🔑 Check if the chip in the key is damaged.
- 🔌 Disconnect the battery for 5 minutes and reconnect (error reset).
- 📱 If the problem remains, diagnostics with a scanner is required (for example, Launch X431).
Engine compartment fuse box: what you need to know
Engine compartment block Nissan Bluebird Sylphy contains fuses and relays responsible for power electrics: starter, generator, cooling fans and fuel pump. Its location depends on the year of manufacture:
- 📅 2012–2017 — the unit is located next to the battery, under a plastic cover.
- 📅 2018–2026 — the block has been moved closer to the windshield, under the decorative trim.
In hybrid versions (e-Power) the fuse is also located here 120A for high voltage battery. Strictly prohibited touch it without special gloves and tools - the voltage in the circuit exceeds 200V!
| Number | Ampere | Purpose | Symptoms of malfunction |
|---|---|---|---|
| 30 | 30A | Radiator cooling fan | Engine overheats, fan does not work |
| 35 | 10A | Fuel pump | The car will not start, there is no pressure in the fuel rail |
| 40 | 40A | Generator | Battery light is on, battery is low |
| 45 | 15A | ABS/ESP | Indicators are on ABS And ESP OFF |
If the fuse is blown #35 (fuel pump), do not rush to change it. First check:
- Are there any fuel leaks under the car (smell of gasoline).
- Is the fuel pump relay working (usually located nearby, indicated
R17). - Is the fuel pump screen clogged (removal of the rear seat is required).
If the fuel pump fuse blows again after replacement, the cause may be a short circuit in the wiring harness under the rear seat. Check the insulation of the wires going to the pump.
How to properly replace a fuse: step-by-step instructions
Replacing the fuse in Nissan Bluebird Sylphy - a simple procedure, but there are nuances that will help you avoid mistakes. You will need:
- 🔧 Tweezers (usually included with the machine).
- 🔦 Flashlight (for illuminating the block).
- 📋 New fuse same denomination.
☑️ Preparing to replace the fuse
Next, follow the algorithm:
- Determine which fuse has blown (using the diagram or visually).
- Using tweezers, carefully remove the faulty fuse. Do not pull it with your fingers - you may damage the contacts.
- Install a new fuse exactly the same denomination. For example, instead of
10Acan't bet15A- this may lead to a fire in the wiring. - Turn on the ignition and check the operation of the circuit.
If after replacement the fuse blows again, this indicates short circuit in the chain. In this case:
- 🔍 Check the wiring for damage (especially in kinks).
- 🛠️ Disconnect consumers connected to this circuit (for example, a radio or additional equipment).
- 🚘 Contact an auto electrician for diagnostics.
⚠️ Attention: Never use bugs (homemade wire fuses). B Nissan Bluebird Sylphy this may cause a fire, especially in the fuel pump or generator circuits. Original fuses cost pennies, but repairs after a short circuit cost thousands.
Typical mistakes when working with fuses
Even experienced drivers sometimes make mistakes that lead to serious damage. Here are the most common:
- ⚡ Using the wrong fuse rating - for example, installation
20Ainstead of10A. This may burn the wiring or control unit. - 🔄 Replacing the fuse without eliminating the cause - if the circuit is closed, the new fuse will blow immediately after installation.
- 🔧 An attempt to repair high-voltage circuits in hybrids - without special training it is deadly.
- 📄 Ignoring the schema - many people change fuses at random, which leads to failure of other systems.
Common mistake - confusion between fuses and relays. The relay looks like a small box with legs and cannot be replaced with a fuse. If the problem is in the relay (for example, the fan does not work), it must be checked separately:
- Remove the relay and shake it - if something rattles inside, it is faulty.
- Swap with a known working relay (for example, a horn relay).
- If the problem remains after replacement, check the circuit with a multimeter.
If the problem persists after replacing the fuse or relay, the cause may be a faulty control unit (ECU) or sensor. In this case, computer diagnostics is required.
Another typical situation is cigarette lighter fuse blown due to the connection of powerful devices (for example, a compressor or inverter). To avoid this:
- 🔌 Use a cigarette lighter with current limitation (maximum
15A). - 🔋 Connect energy-intensive devices directly to the battery via a fuse.
- ⚠️ Do not leave chargers in the cigarette lighter for a long time - they can cause overheating.

Frequently asked questions about fuses in Nissan Bluebird Sylphy
🔍 Why does the fuse blow again after replacement?
This indicates short circuit in the chain. It is necessary to check the wiring for damage, especially in areas of chafing (for example, under rugs or in doorways). It could also be caused by a faulty consumer (for example, a window lift motor or radio).
⚡ Is it possible to install a fuse of a higher rating?
No! This may lead to fire or failure of the control unit. The fuse is designed for a certain current, and replacing it with a more “powerful” one deprives the circuit of protection. If a fuse blows frequently, look for the cause rather than increasing the rating.
🚗 Where can I find a fuse diagram for my model?
The diagram can be found:
- B instruction manual (section
8-30for most models). - On the cover of the fuse box (sometimes there is a decoding there).
- On sites like Fuse-Box.info (there are diagrams for Sylphy different years).
🔋 How to check a fuse without a tester?
You can do this visually or using a “call”:
- Remove the fuse and look at the light - if the thread inside is broken, it has blown.
- Use a known working fuse of the same rating - if the circuit works after replacement, the problem was there.
- To check with a multimeter, set it to mode
callsand touch the fuse contacts with the probes. If there is no sound, the fuse is faulty.
🛠️ What to do if the immobilizer fuse is blown?
If the fuse is blown #25 (10A)responsible for the immobilizer:
- Check the key for damage (especially the chip).
- Disconnect the battery for 5-10 minutes - sometimes this clears the error.
- If the car doesn't start, try a second key.
- If all else fails, diagnostics with a scanner is required (for example, Launch CReader) or contact the dealer to reflash the immobilizer.
