Electrical system of a modern car Nissan Qashqai is a complex network of nodes responsible for lighting, multimedia, security and engine operation. When the dashboard lights suddenly go out or the power window fails, the first cause is often a burnt-out fuse. This is a protective element that absorbs the shock of a power surge, breaking the circuit and saving expensive electronics from failure.
Many crossover owners Nissan Qashqai get lost when trying to find the right element of protection, since there are several of them in the car. The location depends on the year of manufacture, body generation (J10, J11 or J11 restyling) and configuration. In some versions the unit is located in the engine compartment, in others - in the cabin under the instrument panel. Understanding the electrical distribution logic will help you quickly isolate the problem without contacting a service center.
Main areas of protection units placement
In cars Nissan Qashqai engineers have provided two main locations for installing fuse boxes. The first of them is located in the engine compartment, directly next to the battery. This unit is responsible for power consumers such as the generator, cooling system, fuel pump and main engine control relays.
The second unit is located inside the cabin, which makes it more accessible for checking household functions. It is usually hidden under a decorative panel on the dashboard on the driver's or passenger's side, and may also be located under the lid in the glove compartment. It is important to note that some modifications may have an additional unit under the hood responsible for the ABS system and airbags.
Before starting any work, you must make sure that you have accurately determined the location of the required block. If you are looking for the fuse for the headlights, it will most likely be in the engine compartment. And if there is a problem with the cigarette lighter or audio system, then you need to look in the cabin.
⚠️ Attention: Before opening the cover of any fuse box, be sure to turn off the engine and remove the key from the ignition. A short circuit during testing may damage the electronic control unit.
Access to the unit in the engine compartment
To get to the main unit in the engine compartment, you will need to open the hood and lock it in the raised position. The unit is usually a black plastic box located closer to the firewall or battery. On the cover of this block there is often a schematic map of the location of the elements, but this can be erased over time.
To remove the cover, you must carefully unscrew the plastic clips. In most cases, they are located around the perimeter of the lid and require little effort. Be careful not to break the fragile latches, as replacing them may require purchasing a new cover or an entire unit.
After removing the cover, you will see rows of fuses of different sizes and colors. There may also be large relays here, which are often confused with fuses. To remove the elements, use special plastic tweezers, which are usually attached to the inside of the lid or lie next to the block.
- 🔍 Use a flashlight to better illuminate the engine compartment, especially if work is carried out at dusk.
- 🛡️ Check the integrity of all relays, as they can also cause system failure.
- 🔧 Carefully remove the fuses without applying excessive force to the plastic case.
Location of the unit in the car interior
Internal fuse block in Nissan Qashqai usually hidden behind a plastic trim on the left side of the steering column. To access it, you need to sit in the driver's seat and feel for the protruding edge of the panel or a special protrusion for removal.
Sometimes access is achieved by opening the driver's door: the panel can be folded back when you press the latch or simply removed by lightly pulling it towards you. In some trim levels Nissan Qashqai (especially early versions of the J10) the unit is located behind the cover on the passenger side, in the glove compartment niche, which must be lowered all the way.
Once the panel is removed, you will see the same structure as under the hood: rows of fuses and relays. On the inside of the removed cover there is often a diagram that makes it easier to find the desired element. If the diagram is missing or unreadable, you will have to use the manual or table below.
⚠️ Attention: When removing plastic interior panels, avoid sudden movements so as not to damage the fasteners or wiring behind the trim. The fragile interior plastic easily cracks if not handled carefully.

Fuse diagram and decoding
Each fuse in the block has its own purpose, which is indicated in the technical documentation. However, for a quick check, it is often enough to know the main groups. The table below shows the most frequently burned out elements and their functions for the model Nissan Qashqai.
| Designation | Denomination (A) | Purpose | Location |
|---|---|---|---|
| FR_HORN | 10 | Sound signal (horn) | Salon |
| RR_FOG | 15 | Rear fog lights | Under the hood |
| IGN1 | 20 | Ignition and electronics | Salon |
| WIPER | 25 | Windshield cleaner | Under the hood |
| ACC | 15 | Audio system and cigarette lighter | Salon |
Please note that the fuse rating (current strength) must exactly match that indicated on the diagram. Installing an element with a higher rating may lead to a wiring fire, since it will not work if overloaded.
Sometimes a blown fuse cannot be visually determined, since the fuse link may be intact, but the contact is broken. In such cases, it is recommended to use a multimeter in test mode or replace the element with a known good one for testing.
Keep a selection of spare fuses of different ratings in the glove compartment. This will save time if the problem arises on the road away from the service center.
Replacement and diagnostic rules
The process of replacing a burnt-out element does not require special skills, but requires care. First, find the fuse responsible for the non-functioning system. To do this, check the diagram on the unit cover or use the table above.
Using special tweezers, carefully pull out the suspicious fuse. Inspect the clear plastic housing: if the metal bridge inside is torn or charred, the element requires replacement. Insert the new fuse all the way into the same socket.
If after replacement the fuse blows again, this indicates a serious problem in the wiring: a short circuit or a consumer failure. In this case, further independent actions can be dangerous.
☑️ Replacement instructions
What should I do if the fuse blows again?
If the new fuse blows immediately after installation, there is a short circuit in the circuit. Do not try to install a fuse with a higher rating - this will lead to melting of the wiring or a fire. You should immediately contact an auto electrician to diagnose the wiring.
⚠️ Attention: It is prohibited to use twisted copper wire or a “bug” as a fuse. This completely disables the circuit protection and creates a direct risk of vehicle fire.
Features of different generations
It is important to consider that the location of the blocks may differ depending on the generation of the crossover Nissan Qashqai. In the first generation (J10), the unit in the cabin is often located under the panel to the left of the steering wheel, and the circuit is quite simple. In the second generation (J11), the architecture became more complex, and some power fuses were moved to a separate block.
For vehicles with a hybrid or all-wheel drive (4x4), the number of fuses increases. Separate elements are responsible for the all-wheel drive clutch, battery cooling system pumps and electric motors. In such cases, it is better to entrust the troubleshooting to specialists who have access to specialized equipment.
New models with digital control systems may not have the classic fuse box in its usual form. Instead, fusible links are used, integrated into the wiring harnesses, which cannot be replaced without re-soldering or replacing the assembly.
Knowing the exact location of the blocks and the availability of spare parts allows you to eliminate the simplest faults in 5-10 minutes, without wasting time waiting for a tow truck.
Frequently asked questions from owners
Where is the tweezers for removing fuses?
Typically, the tweezers are attached to the inside of the fuse box cover under the hood or in the passenger compartment. If you have lost it, you can use special pliers from car tool kits or carefully remove the element with tweezers with thin jaws, being careful not to damage the contacts.
Is it possible to drive if the main fuse is blown?
No, if the fuse responsible for the ignition system, generator or engine control unit has blown, the vehicle cannot be operated. This can lead to the engine stopping while moving and loss of control. You can drive only if secondary systems burn out (for example, heated seats), but with caution.
Why does the fuse blow when the headlights are turned on?
This indicates a short circuit in the headlight circuit. Possible causes: damage to the wiring insulation, water getting into the headlight, a malfunction of the headlight unit itself or the relay. It is necessary to check the integrity of the wires and the tightness of the optical assembly.
Which fuse color corresponds to which rating?
The color marking is standardized: yellow - 20A, blue - 15A, red - 10A, brown - 7.5A, orange - 5A. However, always check the number printed on the element body as the color may fade or be off-color on older models.
Do I need to disconnect the battery before replacing it?
To replace standard fuses, it is not necessary to disconnect the battery, since they are protected from accidental short circuiting. However, for reliability and to eliminate the risk of sparking when removing large power fuses, it is better to turn off the ignition and remove the negative terminal.
