Owners Nissan Qashqai sooner or later they face the need to replace a blown fuse or check a relay. But where to look for fuse boxes in this crossover? And how not to confuse cigarette lighter fuse with ABS fuse? In this article you will find detailed fuse box diagrams for all generations Qashqai (J10, J11, J12), including an explanation of each element, photo location and practical diagnostic tips.

We will not just list the purpose of fuses - we will explain which of them most often fail due to typical malfunctions (for example, when the power windows fail or the radio does not work), and we will give recommendations on choosing a replacement. You will also learn how to safely remove the fuse without special tweezers and what to do if the problem does not go away after replacing it.

Where are the fuse boxes in the Nissan Qashqai?

B Nissan Qashqai fuses and relays are distributed across three main blocks, the location of which depends on the generation of the car. In models J10 (2007–2013) and J11 (2014–2021) the scheme is almost identical, and in the new J12 (from 2021) changes have occurred. Here's where to look for them:

  • 🔧 Main unit in the cabin — under the instrument panel on the driver’s side (behind the protective cover). B J12 The lid has become transparent for convenience.
  • 🚗 Block under the hood - next to the battery (in J10/J11 on the left, in J12 right). Often covered with a plastic cap labeled FUSE.
  • ⚡ Additional relay block - in J11 And J12 located behind the glove compartment (removal of the trim is required).

B Qashqai J12 (2021+) another mini-unit has appeared under the rear seat - it is responsible for the system ProPILOT and 360° cameras. It is checked only when electronic assistants make errors. To get to the cabin block in J10/J11, just snap off the cover by hand - it is attached to two plastic clips. B J12 You will need a flathead screwdriver to pry the fasteners.

Interior block fuse diagram (J10 and J11)

The interior block is the most popular, since fuses for lighting, multimedia, power windows and other commonly used systems. Below is the transcript for Qashqai J10 And J11 (2007–2021). Please note: fuse numbers may vary depending on equipment (e.g. versions with Bose added separate fuses for the amplifier).

Fuse no. Rating (A) Purpose Symptoms of a problem
1 10 Audio system, navigation The radio does not work, there is no sound
7 15 Cigarette lighter, 12V socket Phone charging does not work, cigarette lighter does not heat up
10 20 Window lifters (all 4 doors) Windows do not go down/up
15 10 Interior and trunk lighting Lights do not light up when doors are opened
23 15 Body Control Module (BCM) Central locking and alarm not working

B Qashqai J11 with the system NissanConnect fuse added №28 (10A) — he is responsible for the telematics module. If the function stops working for you NissanConnect Services (for example, traffic data is not being sent), check this fuse first. Also in J11 The cigarette lighter fuse has been moved to the position №8 (instead of No. 7 as in J10).

⚠️ Attention: In some versions Qashqai J11 with diesel engines (1.5 dCi, 1.6 dCi) fuel pump fuse (№30, 15A) is located in the cabin unit, and not under the hood, as in gasoline models. Its burnout makes it impossible to start the engine!

Fuse box under the hood: what's hiding there?

Engine compartment block Nissan Qashqai is responsible for power electrics: starter, generator, cooling fans, ABS and other critical systems. Fuses of increased ratings are used here (from 20 to 100A), and their replacement requires caution - the wrong choice of rating can lead to fire in the wiring.

Here are the key fuses for the engine compartment J10/J11:

  • 🔥 30A (F3) — radiator cooling fan. If it burns out, the engine overheats at idle.
  • 🚘 60A (F10) — main relay of the injection system. If it fails, the engine will not start.
  • ⚡ 100A (F15) — generator. Burnout leads to battery discharge within 10–15 minutes of driving.
  • 🛑 40A (F20) — ABS/ESP. If there is a malfunction, the lamp lights up ABS on the dashboard.

B Qashqai J12 the engine compartment unit was moved closer to the windshield (to the right of the battery) and received additional fuses for e-Ruchnika (F25, 30A) and systems Intelligent Around View Monitor (F28, 15A). There is also a relay here K5responsible for adaptive cruise control.

💡

Before replacing the fuse under the hood, always disconnect the negative terminal of the battery! Even when the ignition is turned off, some circuits remain energized (for example, the generator).

How to check and replace a fuse: step-by-step instructions

Replacing the fuse in Nissan Qashqai - a simple procedure, but there are nuances that will help you avoid mistakes. Here's what you'll need:

  • 🔍 Flashlight (for inspecting contacts).
  • 🛠️ Fuse tweezers (or pliers with insulated handles).
  • 📋 Multimeter (to check the voltage if the fuse is apparently intact).
  • 🔋 Spare fuses of the required rating (never use “bugs”!).

Algorithm of actions:

  1. Turn off the ignition and remove the negative terminal from the battery (required for the engine compartment unit!).
  2. Find the faulty fuse according to the diagram (see sections above) and remove it with tweezers. If you don't have tweezers, carefully pry the fuse off from the side with a screwdriver.
  3. Inspect the fuse under the light: the burnt thread will be broken. If visually everything is normal, check with a multimeter in continuity mode.
  4. Install a new fuse same denomination. Using a high ampere fuse may cause the wiring to melt!
  5. Connect the battery and check the system operation.

Check the circuit for short circuit with a multimeter|Inspect the wires for melting or damage to the insulation|Check consumers (for example, the cigarette lighter for foreign objects)|If the problem is in the relay, replace it with a known good one-->

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 of a higher rating - this may cause a fire. It is better to contact an auto electrician for diagnosis.

⚠️ Attention: B Qashqai J12 with the system ProPILOT fuse F30 (10A) in the cabin unit is responsible for all-round cameras. If after replacing it the cameras do not work, the system must be rebooted via the diagnostic connector (the procedure takes ~10 minutes).

Common problems and their solutions

Some faults in Nissan Qashqai are associated with fuses more often than others. Here are the most typical cases and how to resolve them:

  • 🔌 Cigarette lighter or 12V socket does not work - check the fuse No.7 (J10) or No.8 (J11/J12). Often the culprit is the connection of powerful devices (for example, a car vacuum cleaner).
  • 🔊 The radio or navigation screen does not turn on - fuse №1 (10A) or relay K1 in the salon block. B J12 also check the fuse №29 (7.5A) for the system Apple CarPlay/Android Auto.
  • 🚪 Power windows don't work - fuse №10 (20A). If the fuse is intact, check the relay K3 or door control unit.
  • 💡 Headlights or side lights do not light up - fuses №5 (10A) (dimensions) and №12 (15A) (low beam) in the cabin block. B J12 LED headlights are controlled by a separate unit under the hood (F18, 15A).

Particular attention should be paid Qashqai with diesel engines. They have a fuse №30 (15A) in the cabin unit it is responsible for the fuel pump. If the car does not start, but the starter turns, check this fuse first. Also in diesel engines the relay often fails. K7, responsible for glow plugs - its malfunction is manifested by a long cold start.

What to do if the generator fuse (F15, 100A) is blown?

This fuse rarely fails on its own. If it burns out, the reasons may be serious:

1. Short circuit in generator circuit — Check the wires from the generator to the battery for damage.

2. Generator diode bridge malfunction — generator replacement or repair is required.

3. Battery problems (for example, internal shorting of cans).

Never replace this fuse with a higher rating! The risk of fire is extremely high. If after replacement the fuse blows again, contact service immediately.

Relay in Nissan Qashqai: purpose and diagnostics

In addition to fuses, Qashqai are used relay, which control powerful consumers: starter, fans, headlights, etc. Unlike fuses, relays do not “burn out,” but fail mechanically (for example, contacts burn out). Checking them requires slightly different skills.

Here are the main relays and their locations:

Designation Location Purpose Symptoms of a problem
K1 Salon block Main injection relay Engine won't start, no spark
K3 Salon block Window lifters The glass does not move, a click is heard when the button is pressed
K5 Engine compartment block Cooling fan The fan does not turn on, the engine overheats
K8 Additional block (behind the glove compartment) Low beam headlights (J11/J12) Headlights do not turn on, fuse is intact

To test the relay, you can use two methods:

  1. Testing with a multimeter: In diode test mode, connect the probes to pins 85 and 86 (relay coil). The resistance should be between 50–120 Ohms. Then apply 12V to these contacts - you should hear a click.
  2. Replacing with a known good one: If you have a similar relay (for example, from a fan), swap them. If the problem has transferred to another system, the relay is faulty.

B Qashqai J12 relay K10 responsible for the system Intelligent Emergency Braking. If it fails, an error light appears on the dashboard "Check the collision avoidance system". This relay cannot be checked with a multimeter - only by replacement.

💡

If the relay clicks, but the system does not work, the problem may be in the wiring or the consumer itself (for example, in the window lift motor).

FAQ: Frequently asked questions about fuses in Nissan Qashqai

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, if there is a short circuit, the wires may melt or catch fire. As a last resort, you can temporarily use a fuse with smaller rating (eg 15A instead of 20A), but replace it with the correct one as soon as possible.

Where can I find a fuse diagram for my Qashqai?

The diagram may differ depending on the year of manufacture and configuration. You will find the exact diagram for your car:

  • B instruction manual (section "Electrical equipment").
  • On fuse box cover (new models have a sticker with decoding).
  • On the website Nissan TechInfo (registration required).

For Qashqai J12 Diagrams are updated frequently - check with dealer for VIN number.

Why does it blow again after replacing the cigarette lighter fuse?

This speaks of short circuit in the chain. Common reasons:

  • Metal objects getting into the cigarette lighter socket.
  • Damage to the insulation of the wires behind the dashboard.
  • Malfunction of the 12V socket (for example, shorted contacts).

Disconnect all devices from the cigarette lighter and check the circuit with a multimeter in continuity mode. If a short is confirmed, contact an auto electrician.

Which fuse controls the heated seats in the Qashqai J11?

The fuse controls the heated seats №18 (20A) in the salon block. If heating does not work, also check:

  • Relay K6 in the salon block.
  • fuse №25 (10A) — he is responsible for the heating control unit.
  • Condition of the buttons on the panel (contacts often oxidize).

B Qashqai J12 heated seats are connected via a separate relay K12 in the additional block behind the glove compartment.

Do I need to change the relay if it clicks, but the system does not work?

A clicking sound means the relay coil is good, but the problem may be:

  • Relay contacts - they could be burnt (check visually).
  • Wiring - open circuit or short circuit after the relay.
  • Consumer (for example, the fan motor burned out).

Try swapping the relay with a similar one (for example, fan relay and headlight relay). If the problem moves, the relay is faulty.
