Fuse box <em>Nissan Qashqai J10</em> (2007–2013): diagram, location and replacement

Nissan Qashqai J10 first generation (2007–2013) - one of the most popular crossovers on the Russian market. Like any car, it requires periodic maintenance of electrical circuits. **Fuse block** is a key element that protects the on-board network from overloads and short circuits. But where is it? How to decipher the scheme? And what to do if the fuse is blown?

In this article you will find detailed fuse box diagram for Qashqai J10 with a breakdown of each element, step-by-step replacement instructions, as well as answers to frequently asked questions. We'll sort it out main mounting block in the cabin, an additional unit under the hood and nuances associated with the relay. The information is relevant for all modifications: gasoline (1.6, 2.0) and diesel (1.5 dCi, 2.0 dCi).

Where is the fuse box located in Nissan Qashqai J10?

B Qashqai J10 There are two main locations for fuses:

• 🚗 Salon block - under the instrument panel on the driver's side. To gain access, you need to open the cover (it is secured with latches).
• 🔧 Engine compartment block — next to the battery, in a plastic box with a lid. Here are located power fuses and a high power relay (for example, for a cooling fan).

On some versions (for example, with 2.0 dCi) may be present additional relay block behind the glove compartment - it is responsible for the climate control system and heated seats. If your furnace or air conditioner is not working, check this particular unit.

⚠️ Attention: On restyled models (2010–2013), the location of the fuses may differ slightly. For example, the cigarette lighter fuse in a pre-Restyle car is located in the interior block under the number 20 (15A), and in Restyle - under 25 (20A).

Diagram and decoding of the cabin unit fuses

Cabin fuse box Nissan Qashqai J10 contains about 40 elements, each of which is responsible for a specific circuit. Below is a table with a breakdown the most popular fuses (you will find the complete diagram in the instruction manual).

Fuse no.	Denomination (A)	Purpose
5	10	Engine control unit (ECU), immobilizer
10	10	Instrument panel, control lights
15	15	Audio system, navigation (if installed)
20	15 (pre-style) / 20 (restyle)	Cigarette lighter, 12V socket in trunk
30	10	Window lifters (all doors)

🔍 How to find the right fuse? On the inside of the cabin unit cover there is a diagram with numbers and purpose. If the inscriptions are erased, use tweezers with light - it will help you remove the fuse without the risk of damaging neighboring ones.

Important: Fuse 20 (cigarette lighter) often fails due to the use of powerful devices (for example, compressors or inverters). If it burns repeatedly, check the circuit for a short circuit or install a power strip with a separate fuse.

Underhood fuse and relay box: what is where?

Engine compartment block Qashqai J10 located next to the battery and covered with a black plastic cover. Here are:

• ⚡ Power fuses (from 30A to 100A) - are responsible for circuits with high consumption (for example, generator, starter).
• 🔄 Relay — control the operation of the cooling fan, fuel pump, headlights, etc.
• 🔋 Generator fuse (100A) — often fails when “lighting” other cars.

⚠️ Attention: If after replacing the fuse 100A (the generator) burns out again, do not install an element of a higher value - this may lead to a fire in the wiring. The cause is usually a faulty alternator diode bridge or a short circuit in the charging circuit.

Below are diagrams of the location of the relay in the engine compartment (relevant for most versions Qashqai J10):

Relay designation	Purpose
R1	Cooling Fan Relay (Low Speed)
R2	Cooling Fan Relay (High Speed)
R5	Fuel pump relay
R7	Low beam relay

💡 Advice: If the cooling fan is not working, check more than just the relay R1 And R2, but also fuse 40A in the same block. Often the problem lies in the oxidized contacts of the temperature sensor connector.

How to test a relay without a multimeter?

If you suspect that a relay is faulty, you can temporarily swap it with a known working one (for example, a horn relay R3). If after replacement the problem disappears, the relay is faulty.

Step-by-step instructions: how to replace the fuse?

Replacing the fuse in Nissan Qashqai J10 - a simple procedure, but requires care. Follow the instructions:

1. Turn off the power. Turn off the ignition and remove the negative terminal from the battery.
2. Find the block. For the interior unit, open the cover under the steering wheel (it is secured with latches). For the engine compartment, remove the plastic cover next to the battery.
3. Remove the fuse. Use the tweezers that came with the car. If it is not there, you can carefully pry the fuse off with a screwdriver.
4. Check integrity. A blown fuse has a broken filament inside. If in doubt, replace it with a new one with same denomination.
5. Install a new fuse. Insert it until it clicks. Make sure the contacts are clean (clean them with alcohol if necessary).

⚠️ Attention: If the new fuse blows immediately after installation, do not try to place an element of a higher value - this may cause a fire! It is necessary to diagnose the circuit for a short circuit (for example, using a multimeter in continuity mode).

Common problems and their causes

Owners Nissan Qashqai J10 often encounter typical faults related to fuses:

• 🔌 The cigarette lighter does not work. Reason: fuse blown 20 (or 25 in restyling) due to overload. Solution: Replace the fuse and check the connected devices.
• 💡 The headlights don't come on. Reason: fuse 15A (35 - low beam, 36 - distant) or relay R7. Solution: Also check the lamps and connectors.
• 🚪 The power windows don't work. Reason: fuse 30 (10A) or motor malfunction. Solution: If the problem persists after replacing the fuse, check the power window control unit.
• 🔊 The audio system does not work. Reason: fuse 15 (15A) or a break in the antenna circuit. Solution: if the fuse is intact, reset the radio settings (hold the button POWER 10 seconds).

How to diagnose a faulty fuse?

If you suspect that a fuse has blown, but it is not visually obvious, use multimeter:

1. Set the multimeter to mode calls (or resistance measurements).
2. Touch the fuse terminals with the probes. If resistance 0 ohm - the fuse is OK. If ∞ (infinity) - burned out.
3. To check the voltage: turn on the ignition, connect the probes to the contacts of the fuse socket. If there is voltage on one contact and not on the other, the fuse is faulty.

🔧 Alternative method: If you don't have a multimeter, you can use control lamp (12V). Connect it to the fuse contacts - if the lamp does not light, the circuit is broken.

Example: If the heater fan does not work, check the fuse 40A in the engine compartment and relay R4. If they are working, but the fan does not turn on, the problem may be speed resistor (located under the glove compartment) or broken wiring.

FAQ: Frequently asked questions about fuses Nissan Qashqai J10

🔋 Is it possible to install a fuse of a higher rating if it constantly burns out?

No! Installing an oversized fuse may result in overheating of wiring and even fire. If the fuse burns out repeatedly, look for the cause: a short circuit, a faulty consumer (for example, a motor or compressor) or poor contact in the connectors.

🚗 Where to find the fuse diagram for your version Qashqai J10?

The diagram is printed on the inside of the fuse box cover. If the inscriptions are erased, download instruction manual for your year of manufacture (for example, on the website Nissan Manuals). For restyled models (2010–2013), the scheme may differ!

⚡ What to do if after replacing the cigarette lighter fuse it burns out again?

Most likely the problem is short circuit or circuit overload. Check:

• The quality of contacts in a 12V socket (often oxidizes).
• Connected devices (eg compressor or inverter).
• Wiring from the cigarette lighter to the fuse box (may be frayed).

If you are not confident in your abilities, contact an auto electrician for diagnostics.

🔧 Which fuse is responsible for the central locking?

Behind the central lock Qashqai J10 fuse responds 25 (10A) in the cabin block. If the lock does not work, check also relay R6 in the engine compartment and control unit (BCM).

💡 Why do headlight fuses burn?

Common reasons:

• Lamps installed increased power (For example, H7 100W instead of 55W).
• Short circuit in headlight connector (check for moisture or oxidation).
• Malfunction xenon ignition unit (if installed).

Solution: return the stock lamps and check the circuit with a multimeter.
