Nissan Sunny - one of the most popular models of the Japanese automaker, produced in several generations (B13, B14, B15). Despite its reliability, even in this car fuses periodically blow, which leads to electrical equipment failure. Unlike modern cars, where fuse blocks are standardized, Sunny their location depends on the year of manufacture and configuration. This article will help you quickly find the right fuse, understand its purpose and avoid common mistakes when replacing.
We'll figure out where they are main and additional fuse blocks, let's give detailed diagrams for each generation, and we will also tell you how to correctly diagnose the malfunction. We will pay special attention fuses responsible for critical systems (ignition, fuel pump, ECU) - blowing them can leave the car immobilized.
Where are the fuse boxes in the Nissan Sunny?
Depending on generation Nissan Sunny fuse boxes may be located in different places. General rule: main unit is always in the salon, and additional (if any) - under the hood. Below is a table with the exact location for each body.
| Generation | Main fuse box | Additional block (relay) |
|---|---|---|
| B13 (1990–1995) | To the left of the steering column, under the instrument panel (behind the plastic cover) | In the engine compartment, next to the battery (black plastic box) |
| B14 (1995–2000) | Under the glove compartment, passenger side (lid with latches) | Near the engine control unit (ECU), under the hood |
| B15 (2000–2006) | At the bottom of the center console, under the plastic panel (next to the gas pedal) | On the left mudguard, next to the mounting block |
On some modifications (for example, Sunny N16 for the European market) the fuse box can be moved to the trunk - this is rare, but it is worth checking if you cannot find it in the usual places. Also note that on right-hand drive vehicles (Japanese versions) the location is mirrored.
⚠️ Attention: On Nissan Sunny B14 with air conditioning, the additional relay box is often hidden behind the glove compartment. To get to it, you will need to remove the plastic lining - do this carefully so as not to break the clips.
Fuse diagram for Nissan Sunny B13 (1990–1995)
B Sunny B13 The main fuse box contains 15–20 elements, depending on the configuration. Below is the standard layout for most versions:
- 🔋 F1 (10A) — Dimensional lamps (left side), license plate illumination
- 🔦 F2 (10A) — Dimensional lamps (right side), instrument panel lighting
- 🚗 F3 (10A) — Turn signals, hazard warning lights
- 💡 F4 (15A) — Low beam (left headlight)
- 🔍 F5 (15A) — Low beam (right headlight), headlight range control
- 🔥 F6 (10A) — Fuel pump, injection system (critical fuse!)
- 📻 F7 (10A) - Radio, cigarette lighter
- 🔑 F8 (10A) — Immobilizer, central locking
Feature B13 - fuse F6 is responsible for the operation of the fuel pump. If the car does not start, but the starter turns, check it first. Also in this generation the fuse often fails F10 (15A), responsible for the cooling fan - its burnout leads to overheating of the engine.

Fuse location in Nissan Sunny B14 (1995–2000)
B Sunny B14 The fuse box has become more compact, but the number of elements has increased to 20–25. There are separate fuses for ECU, ABS (if installed) and electric power steering. Scheme for the basic configuration:
- 🔌 F1 (10A) — Interior lighting, trunk lamp
- 🚨 F2 (10A) — Sound signal, brake lights
- 🔄 F3 (10A) — Windshield wipers, windshield washer
- 🔥 F4 (15A) — Engine ECU (if a burnout occurs, the car stalls or does not start)
- ⚡ F5 (20A) — Heater fan, heated rear window
- 📡 F6 (10A) — Antenna, clock, on-board computer
- 🚪 F7 (15A) — Electrical package (window lifters, mirrors)
B B14 special attention should be paid to the fuse F4 - he protects electronic control unit (ECU). If this fuse blows, the car may stall while driving or refuse to start. Also often fails F5, responsible for heating the rear window - its burnout leads to fogging of the windows in rainy weather.
If in Sunny B14 The cigarette lighter stopped working, check not only the fuse F12 (15A), but also the contacts in the block - they often oxidize due to moisture.
Where to look for fuses in Nissan Sunny B15 (2000–2006)
Sunny B15 - last generation, Released under this name (in some countries sold as Nissan Almera N16). Here the fuse box has become more modern, but also more overloaded. Main elements:
- 🔋 F1 (10A) — Dimensions lamps, instrument lighting
- 🚗 F2 (10A) — Turn indicators, hazard lights
- 💡 F3 (15A) — Low beam (left headlight), corrector
- 🔍 F4 (15A) — Low beam (right headlight)
- 🔥 F5 (10A) — Fuel pump, injectors (critical!)
- ⚡ F6 (20A) — Cooling fan, air conditioning
- 📻 F7 (15A) — Radio, cigarette lighter, 12V socket
- 🔑 F8 (10A) — Immobilizer, alarm
- 🚪 F9 (20A) — Central locking, power windows
- 🔄 F10 (10A) — Windshield wipers, washer
B B15 fuse F5 is responsible not only for the fuel pump, but also for injectors. If the car jerks while driving or stalls, check it first. Also in this generation there was a separate fuse for ABS (F12, 10A) — when it burns out, the corresponding lamp lights up on the dashboard.
⚠️ Attention: B Sunny B15 with automatic transmission there is a separate fuse F11 (10A) for automatic transmission solenoids. If it burns out, the car won't change gears or gets stuck at one speed.
How to check and replace a fuse: step-by-step instructions
Replacing the fuse in Nissan Sunny - a simple procedure, but requires care. Here is a step-by-step algorithm:
- Turn off the ignition and remove the key from the lock. This will prevent short circuit.
- Find the fuse box (see table above) and remove the cover. It is usually secured with latches or a single screw.
- Identify the faulty fuse. Visually inspect the elements - a burnt-out one will have a broken thread or a blackened body. You can also use a multimeter in dialing mode.
- Remove the fuse special forceps (usually included with the machine) or tweezers. Do not use metal tools under any circumstances - they may short-circuit the contacts.
- Install a new fuse the same denomination. Using a fuse with a large amperage will lead to a fire!
- Check the operation of the equipment. If the fuse blows again, look for a short in the circuit.

If after replacement the fuse blows again, this means that there is a fault in the circuit. short circuit. In this case it is necessary:
- 🔍 Check the wires for damage to the insulation.
- 🔌 Disconnect consumers (for example, a radio or headlights) and connect them one by one to identify the problematic one.
- 📊 Use a multimeter to find a section of the circuit with zero resistance.
Typical fuse problems and their solutions
Owners Nissan Sunny often encounter recurring problems with fuses. Here are the most common cases and how to resolve them:
| Problem | Possible reason | Solution |
|---|---|---|
| The car does not start, the starter does not turn | Fuse blown F6 (B13) or F5 (B15) (fuel pump/ECU) | Replace the fuse. If it burns out again, check the fuel pump and the ECU power circuit. |
| Power windows don't work | Burnt out F7 (B14) or F9 (B15), or the relay is faulty | Replace the fuse. Check relay K5 (located in the same block) |
| Low beam headlights do not light up | Burnt out F4/F5 (B13) or F3/F4 (B15) | Replace fuses. Check lamps and relays K1 (responsible for light) |
| Cigarette lighter doesn't work | Burnt out F7 (B13/B14/B15) or contacts have oxidized | Replace the fuse. Clean the block contacts with fine sandpaper |
| Cooling fan does not turn on | Burnt out F5 (B14) or F6 (B15), temperature sensor is faulty | Replace the fuse. Check temperature sensor and fan relay |
If the fuse blows immediately after replacement, do not rush to install a new one - this may lead to a fire. First disconnect consumers (for example, if it is the cigarette lighter circuit, turn off the radio and other devices) and check the circuit for a short circuit.
What should I do if the fuse blows again?
If the fuse blows immediately after replacement, there is a short circuit in the circuit. Algorithm of actions:
1. Disconnect all consumers connected to this circuit (for example, if it is a cigarette lighter fuse, disconnect the radio, recorder, chargers).
2. Install a new fuse. If it does not burn out, connect the devices one by one to identify the problem.
3. If the fuse blows even without load, look for damage to the wiring. Inspect the wires for melting or bare areas, especially in kinks (under the hood, near the doors).
4. Use the multimeter in continuity mode to find a section of the circuit with zero resistance.
5. If you cannot find the reason yourself, contact an auto electrician. In some cases, the short circuit may be hidden under the dashboard or in the wiring harnesses.
Where to buy fuses for Nissan Sunny and which ones to choose
Fuses for Nissan Sunny They are sold at any auto store, but it is important to choose quality parts. Here's what you need to know:
- 🔧 Fuse type: B Sunny fuses are used knife type (blade fuse) standard sizes:
- Mini (APM/ATM) — for circuits with low current (10A–15A).
- Standard (APR/ATO) - for most circuits (10A–30A).
- Maxi - rarely used, only for powerful consumers (for example, cooling fan).
- 🏷️ Manufacturers: It is better to choose fuses from proven brands:
- Hella - German quality, reliable contacts.
- Bosch - universal, suitable for most cars.
- Littlefuse - original fuses used on the conveyor Nissan.
- ⚠️ What to avoid: Do not buy fuses from unknown Chinese brands - they often have poor contact and may melt.
The cost of fuses is low: a standard set of 10 pieces will cost 150–300 rubles. If you don’t want to waste time searching, you can order through online stores (Exist.ru, Autodoc, AliExpress), but pay attention to the reviews about the seller.
Never use "bugs" (homemade jumpers) instead of fuses! This may cause a fire in the vehicle. If you don't have the correct fuse on hand, temporarily use a fuse with a lower rating (for example, change from 15A to 10A), but replace it with the correct one as soon as possible.
FAQ: Frequently asked questions about Nissan Sunny fuses
Is it possible to use a fuse with a higher rating if you don’t have the right one on hand?
No, this is extremely dangerous! The fuse is designed for a certain current, and if you install a more powerful one, it will not work in the event of a short circuit, which can lead to a fire. As a last resort, you can temporarily use a fuse with smaller rating (eg 10A instead of 15A), but replace it with the correct one as soon as possible.
Why does the cigarette lighter fuse keep blowing?
This is one of the most common problems. Reasons:
- Using powerful devices (such as a car vacuum cleaner or compressor) that exceed the permissible load (usually 15A).
- Short circuit in the cigarette lighter socket (oxidation of contacts or contact with metal objects).
- There is a malfunction of the radio or other equipment connected to this circuit.
Solution: Unplug all devices, replace the fuse and connect them one by one to identify the problem.
Where is the fuel pump relay located in Nissan Sunny B14?
B Sunny B14 The fuel pump relay is in additional block under the hood, next to the ECU. It is usually marked as Fuel Pump Relay or has a number K3. To get to it, remove the unit cover (attached with two latches). If the relay is faulty, the car will not start, even if the fuse is good.
How to check a fuse without a multimeter?
You can do this visually or using a test lamp:
- Visual inspection: Take out the fuse and look at the light - if the thread inside is broken or the body is blackened, the fuse has blown.
- Test lamp: Turn on the ignition, connect one contact of the lamp to ground (a metal part of the body), and the second - alternately to the fuse terminals. If the lamp lights up on only one terminal, the fuse is faulty.
What should I do if the equipment does not work after replacing the fuse?
Possible reasons:
- The equipment itself is faulty (for example, a lamp or window lift motor).
- The relay responsible for this circuit has burned out.
- Poor contact in the fuse box (oxidation or broken terminal).
- Broken wire in the circuit.
Check the relay (usually it is located next to the fuse), and also inspect the contacts in the block - if necessary, clean them with alcohol or fine sandpaper.
