Owners Nissan Bluebird Sylphy (especially 2020-2026 models) sooner or later you will have to check or replace fuses. These small protective elements are responsible for the stable operation of electronics - from headlights and power windows to the multimedia system and ignition system. However, find the correct fuse in relay and fuse box It can be difficult without a diagram: the manufacturer does not always place detailed markings under the cover.
In this article we will look at where exactly the fuse blocks are located in Bluebird Sylphy (including the version for the Russian market), we present decoding of each element indicating the current strength, and also explain how to correctly diagnose and replace burnt out parts. We will pay special attention to typical problems - for example, why the cigarette lighter fuse often fails or why turn signals do not work after replacing lamps. If you don’t want to waste time on service or are afraid of mixing up denominations, our instructions will help you complete the task in 10–15 minutes.
Where are the fuse boxes in the Nissan Bluebird Sylphy?
B Nissan Bluebird Sylphy (including restyled versions) provided two main fuse boxes:
- 🔧 Main unit in the cabin — located to the left of the steering column, behind the plastic cover. To gain access, just pull the cover towards you (it is secured with latches).
- 🚗 Additional block under the hood — located next to the battery, in a plastic box with a black lid. High power fuses are located here (for example, for the cooling fan or injection system).
In some configurations (for example, with Nissan Connect or ProPilot) may be present third mini-block - it is usually hidden behind the glove compartment or under the center console. Its purpose is to protect the multimedia system and all-round cameras. If your screen or cameras are not working, check this unit first.
Important: there is often a diagram on the block covers, but it may be in Japanese or English. Below we will give Russian transcript for all generations Sylphy, including export versions.
- Inside
- Under the hood
- In the multimedia block
- I don't know where to look
Fuse diagram in the interior block (2020–2026)
The interior block is the most popular, since fuses for everyday systems are concentrated here: lighting, power windows, audio systems, etc. Below is a table with current transcript for Nissan Bluebird Sylphy last years of release. Please note: fuse numbers may vary depending on equipment (for example, for versions with Bose or LED headlights).
| Fuse no. | Denomination (A) | Purpose | Symptoms of a problem |
|---|---|---|---|
| F1 | 10 | Engine control system (ECU) | The engine stalls and lights up Check Engine |
| F5 | 15 | Cigarette lighter/socket 12V | Phone charging and cigarette lighter not working |
| F10 | 7.5 | Turn signals and hazard warning lights | Turn signals do not flash, hazard warning button does not work |
| F14 | 20 | Window lifters (all 4 doors) | The windows don't work, you can hear the relay clicking |
| F20 | 10 | Audio system and navigation | The radio does not turn on, there is no sound |
If you do not find the required fuse in the table, check additional diagram on the back of the block cover. Sometimes the manufacturer makes changes to the electrical circuit without notice (for example, in models for Southeast Asia The cigarette lighter fuse may be numbered F7 instead of F5).
Before replacing a fuse, always check it with a multimeter in the “continuity” mode - a break is not always visually noticeable, especially if the case is darkened.
Fuses under the hood: what they protect and how to check
The block under the hood is responsible for power electrics: starter, generator, injection system, cooling fans, etc. Fuses are used here higher denomination (from 20 to 100 A), and replacing them requires caution - the wrong choice can lead to a fire in the wiring.
Location of the unit: next to the battery, in a plastic box with a black lid (sometimes marked as Fuse & Relay Box). To open it, press the latches on the sides. Inside you will find:
- ⚡ Fuse F30 (30A) - main fuse for the injection system. If it burns out, the engine will not start.
- ⚡ Fuse F40 (50A) - generator circuit. If there is a malfunction, the battery will not charge.
- ⚡ Fuse F50 (100A) — starter power circuit. It burns out extremely rarely, but if this happens, the car will not start.
Warning: never replace fuses under the hood with bugs (wire jumpers). This may cause a fire! If the fuse blows again after replacement, look for short circuit in the circuit (for example, exposed wires or a damaged harness).
How to check a fuse without a multimeter?
If you don't have a tester at hand, you can use a 12V light bulb with two wires. Connect one wire to ground (body), and the second one in turn to the fuse terminals. If the light does not light up on any of the terminals, the fuse has blown.
Typical problems and solutions: why fuses burn
If the fuse is in Nissan Bluebird Sylphy burns out regularly, this is a signal about hidden fault. Let's look at the most common causes and ways to eliminate them:
- Cigarette lighter (F5, 15A):
Burns out due to the use of powerful devices (for example, compressors or inverters). Solution: Connect devices through a power strip with its own fuse or use the outlet in the trunk (if available).
- Turn signals (F10, 7.5A):
It often fails after replacing lamps with LED ones - they consume less current, and the relay “does not see” the load. Solution: install relay for LED or go back to halogen bulbs.
- Window lifters (F14, 20A):
It burns out when the glass freezes or foreign objects get into the mechanism. Solution: Clean the guides and lubricate them with silicone grease.
Critical information: if in your Bluebird Sylphy system installed Nissan Safety Shield 360 (radar sensors, cameras), never replace the fuses of the unit ADAS (usually F25–F28) without diagnostics! An incorrect rating can damage the control module, and replacing it will cost 50,000+ rubles.
90% of cases of repeated blown fuses are due to a short circuit in the circuit. If replacement does not help, check the wiring for melting or damage to the insulation.
How to replace a fuse: step-by-step instructions
Replacing the fuse in Nissan Bluebird Sylphy takes no more than 5 minutes if you know the sequence of actions. You will need:
- 🔧 Tweezers (usually included with the car, in the fuse box).
- 🔦 Flashlight (to see the markings better).
- 📋 New fuse same denomination (see table above).
Step-by-step algorithm:
- Turn off the ignition and remove the negative terminal from the battery (especially if you are working with the unit under the hood).
- Find the faulty fuse using the diagram or visually (a blown fuse usually has a broken thread inside).
- Use tweezers to remove the old fuse and install the new one. Do not force it in!
- Check the operation of the system for which it is responsible.
☑️ Preparing to replace the fuse
If after replacement the fuse burns out again, do not repeat the procedure - this may indicate a serious malfunction (for example, a short in the wiring harness or a consumer failure). In this case, it is better to contact an electrician with a diagnostic scanner.
⚠️ Attention: In some versions Bluebird Sylphy (for example, with a hybrid installation e-Power) The high voltage fuses are located in a separate block under the rear seat. Replacing them requires special training - do not start work without insulating gloves and a discharged capacitor!

Frequently asked questions about Nissan Bluebird Sylphy fuses
Is it possible to install a fuse of a higher rating if it constantly blows?
No! This is dangerous - the wiring is designed for a certain current, and if the fuse does not trip in time, the insulation may melt or the harness may catch fire. If the fuse blows frequently, look for the cause (short circuit or faulty consumer).
Where is the fuse for the radio in the 2023 Sylphy?
In the cabin block under number F20 (10A). If the radio does not work after replacing, also check the fuse F22 (7.5A) - it is responsible for the antenna amplifier.
Why did it blow again after replacing the cigarette lighter fuse?
Most likely, there is a short circuit in the 12V socket (for example, due to a metal object or damaged contacts). Disassemble the cigarette lighter and check the circuit with a multimeter.
Which fuse controls the low beam on the Bluebird Sylphy?
Two fuses are responsible for the low beam: F3 (10A) for left headlight and F4 (10A) for right. If only one burns out, check the lamp and wiring on the appropriate side.
Do I need to remove the battery when replacing fuses under the hood?
It is advisable to remove the negative terminal, especially if you are working with high rated fuses (50A and higher). This will protect against accidental short circuits when the tool touches metal parts of the body.
