Owners Nissan Qashqai The first generation (2008 release) sooner or later has to face the need to check or replace fuses. These small but critical elements protect the vehicle's electrical circuits from overloads and short circuits. Without working fuses, the headlights, power windows, audio system may fail, or even the engine may not start.
In this article you will find detailed fuse layout diagram for Nissan Qashqai J10 2008 model year, their decoding by numbers and amperage, as well as step-by-step instructions for replacement. We took into account the features of trim levels with gasoline (MR20DE, HR16DE) and diesel (M9R) engines, since block diagrams may differ slightly. If this is your first time opening the hood or fuse box, don’t worry: the process is simpler than it seems at first glance.
Where are the fuse boxes in the Nissan Qashqai 2008
B Qashqai J10 There are two main fuse blocks:
- 🔧 Main unit in the cabin — located to the left of the steering column, behind the plastic cover. Access to it opens by turning three clamps.
- ⚡ Additional block under the hood — located next to the battery, in a plastic box with a lid. High power fuses are located here (for example, for the cooling fan or ABS).
Also in some configurations may be present third block — it is hidden behind the glove compartment and is responsible for the audio system or climate control. However, the base versions of 2008 often do not have it.
- In the salon block
- In the engine compartment
- In the block behind the glove compartment
- I don't know where to look
- Never changed
To avoid confusion, remember a simple rule: fuses for small electronics (interior light, cigarette lighter, radio) are almost always located in the cabin unit. But power load (starter, alternator, ABS) take over the fuses under the hood.
Diagram and decoding of the cabin unit fuses
Salon block Nissan Qashqai 2008 contains fuses of 10–30 A, which are responsible for most electrical consumers. Below is a table with a breakdown by numbers (numbering goes from left to right, top to bottom):
| Fuse no. | Amperage (A) | Purpose | Notes |
|---|---|---|---|
| 1 | 10 | Side light bulbs (left side) | Also responsible for the license plate illumination |
| 5 | 15 | Audio system, navigation | When burned out, radio settings are reset |
| 10 | 20 | Cigarette lighter, 12V socket | Often fails when connecting powerful devices |
| 15 | 10 | Body Control Module (BCM) | If there is a malfunction, the power windows may not work. |
| 20 | 25 | Heated rear window | Check if the threads are not heating up |
Important: in diesel versions, fuse No. 12 (15A) is responsible for the glow plugs - its burnout can lead to problems with starting the engine in cold weather.

Engine compartment fuse diagram
Engine compartment block Qashqai 2008 contains more powerful fuses (from 30 to 100 A), as well as relays. Here are the elements responsible for:
- 🔥 Generator and starter (80–100 A fuses)
- ❄️ Radiator cooling fan (30–40 A)
- 🚗 ABS and ESP (10–15 A, depending on configuration)
- 💡 Low/high beam headlights (15–20 A)
The peculiarity of this block is the presence relay (small black boxes), which can also fail. For example, if the cooling fan is not working, check more than just the fuse F3 (40A), but also a relay R5.
How to distinguish a fuse from a relay?
The fuse is a transparent plastic case with a metal thread inside. The relay is a black or gray rectangular block with legs. There is usually a diagram with symbols on the engine compartment cover.
Below is a table with key fuses for the engine compartment:
| Designation | Amperage (A) | Purpose | Symptoms of malfunction |
|---|---|---|---|
| F1 | 100 | Main fuse (connection with battery) | When a burnout occurs, the car is completely de-energized. |
| F3 | 40 | Cooling fan | Engine overheats, fan does not work |
| F7 | 30 | Fuel pump (gasoline) | The engine does not start, there is no pressure in the fuel rail |
| F10 | 15 | ABS/ESP | The ABS light on the dashboard is on |
Before replacing the fuse under the hood, always remove the negative terminal from the battery - this will protect against a short circuit.
How to properly replace a fuse: step-by-step instructions
Replacing the fuse in Nissan Qashqai 2008 takes no more than 5 minutes, but requires care. Follow this algorithm:
- Turn off the power: For the interior unit, simply remove the key from the ignition. For the engine compartment, remove the terminal from the battery.
- Find the faulty fuse: Visually check the thread for breakage or use a multimeter in continuity mode.
- Remove the old fuse special forceps (they are in the block) or tweezers. Never use metal tools!
- Install new with the same amperage. Installing a fuse with a higher rating may cause a fire!
☑️ Preparing to replace the fuse
If after replacement the fuse blows again, this is a signal about short circuit in the chain. In this case, do not try to install a fuse with a reserve amperage! Contact an auto electrician for diagnosis.
⚠️ Attention: in diesel versions Qashqai fuel pump fuse (F7, 30A) is often confused with a glow plug fuse (F12, 15A). Their replacement is not interchangeable!
Common problems and their causes
Some fuses in Nissan Qashqai 2008 burn out more often than others. Here are the most common cases:
- 🔌 Cigarette lighter fuse (20A) — fails when connecting powerful devices (vacuum cleaners, compressors). Solution: use a power strip with protection.
- 💡 Low beam fuse (15A) — burns out when installing LED lamps with incorrect polarity.
- ❄️ Fan fuse (40A) — suffers from moisture getting into the connectors or a short circuit in the fan motor.
- 🎵 Audio fuse (15A) - may burn out if the subwoofer or amplifier is connected incorrectly.
If you have the same fuse blowing regularly, check:
- Quality of contacts in pads (oxidation, corrosion).
- Condition of wiring for chafing or short circuit.
- Connected devices (for example, a DVR with an incorrect connection diagram).
90% of cases of frequent blown fuses are associated with non-standard equipment (alarm systems, radios, LED lamps).
Where to buy fuses for Nissan Qashqai 2008
Fuses for Qashqai J10 sold in three types:
- 🛒 Original Nissan - the most reliable, but expensive (from 50 rubles per piece). Article number for the interior unit:
28510-JM00A. - 🔧 Analogs (Bosch, Hella, Vibe) - cheaper (20–40 rubles), but the quality depends on the manufacturer.
- 📦 Universal Fuse Kits — convenient to have in the glove compartment (set costs from 200 rubles).
It is better to buy fuses in trusted stores:
- Online: Exist.ru, Autodoc, Kolesa-Darom (there is a filter by car model).
- Offline: shops AutoSpetsCenter, Lada-Image, or chain hypermarkets (Obi, Leroy Merlin - in auto goods departments).
⚠️ Attention: Avoid buying fuses at markets or from dubious sellers. Cheap fakes may not work if overloaded, which will lead to a fire in the wiring.
When purchasing, pay attention to color coding:
- Red - 10A
- Blue - 15A
- Yellow - 20A
- Green - 30A
This will help you quickly navigate when replacing.
FAQ: Frequently asked questions about Nissan Qashqai 2008 fuses
Is it possible to install a fuse of a higher rating if it constantly blows?
No! This may cause a fire. If the fuse blows frequently, look for the cause of the short circuit in the circuit. As a last resort, temporarily use a fuse with same denomination, but from a different manufacturer (for example, instead of a cheap Chinese one, put Bosch).
How to check a fuse without a multimeter?
Visually: shine a flashlight through the fuse housing. If the thread inside is broken, it burns out. You can also replace a suspicious fuse with a known working fuse of the same rating (for example, from the cigarette lighter circuit).
Where is the central locking fuse located?
This is a fuse in the interior unit №14 (10A). If the central locking does not work, also check the relay R3 in the engine compartment and the power circuit of the control unit (BCM).
Why did it blow again after replacing the cigarette lighter fuse?
Most likely, the problem is in the connected device (for example, a faulty tire compressor) or in the 12V outlet itself (short circuit internally). Check the socket contacts for melting.
Which fuse controls the radio?
This is a fuse in the interior unit №5 (15A). If after replacing it the radio does not work, also check the fuse №6 (10A), responsible for the settings memory.
