Nissan Qashqai J10 first generation with engine 2.0 l (MR20DE) - one of the most popular crossovers on the secondary market. However, even such reliable machines eventually develop electrical problems, and in 80% of cases, the culprit is blown fuses or relays. Where to look for the fuse box in this car? How to properly maintain it? And why do some fuses blow over and over again?

In this article you will find detailed fuse box diagram for Qashqai J10 2.0 (2007–2013), decoding of each element, as well as unique tips for diagnosing faults that are not in standard manuals. We will analyze common mistakes when replacing, tell you how to check a fuse without a tester, and give recommendations on choosing high-quality spare parts.

Where is the fuse box located in Nissan Qashqai J10 2.0?

B Qashqai J10 installed two main fuse boxes:

  • 🔧 Main unit — located in the cabin, under the instrument panel on the driver’s side. To access it, you need to open the door (it is secured with a latch) and unclip the lid.
  • ⚡ Additional relay block — located in the engine compartment, next to the battery (under the plastic cover). Powerful relays for the starter, fans and fuel pump are located here.

Important: in some configurations (for example, with AWD or CVT) the diagram may differ slightly. If your Qashqai equipped system Around View Monitor, an additional relay for cameras will appear in the block.

To avoid confusion, remember a simple rule: all fuses related to lighting, multimedia and climate control are located in the cabin unit. And the relay for power circuits (starter, generator, fans) is under the hood.

How to check a fuse without a tester?

If you don’t have a multimeter at hand, you can use a simple method:

1. Pull out the fuse and look at the light - if the thread inside is broken, it has burned out.

2. Replace the suspicious fuse with a known working fuse of the same rating (for example, from the cigarette lighter circuit).

3. If the device worked after replacement, the problem was in the fuse.

Typical faults and why fuses burn

B Nissan Qashqai J10 There are several “weak points” due to which fuses fail most often:

  • 🔥 F7 (cigarette lighter) - lights up due to the use of powerful devices (for example, compressors or inverters) or a short circuit in the socket. Often the problem is oxidized contacts.
  • 💡 F10 (audio system) - burns out during power surges or if the speakers Bose a short circuit has occurred. Check the wires behind the radio!
  • ❄️ F18 (heated glass) — fails due to breakage of heating threads or moisture getting into the connectors. Inspect the glass for cracks in the conductive paths.
  • 🚗 F25 (ABS/ESP) - If the fuse burns repeatedly, check the wheel sensors for corrosion or broken wiring.

Experienced car owners note that in Qashqai J10 with CVT the fuse often fails F30 (10A)responsible for gear selector. If after replacement it burns out again, the problem may be a faulty one. automatic transmission control unit or a short in the wiring harness under the center console.

⚠️ Attention! If the fuse blows immediately after replacement, don't bug (wire or fuse of a higher rating)! This may cause the wiring to catch fire. Instead, test the circuit for short circuits using a multimeter in continuity mode.

Step-by-step instructions: how to replace the fuse in Nissan Qashqai J10

Replacing a fuse is a simple procedure, but there are some nuances here too. Follow these instructions to avoid damaging the unit:

  1. Turn off the ignition and remove the key from the lock. If you are replacing a fuse in the engine compartment, remove the terminal from the battery (first "minus").
  2. Find the faulty fuse according to the diagram (see section above) and carefully remove it plastic tweezers (it is usually attached to the block cover).
  3. Install a new fuse same denomination. Never use bugs or fuses with a different ampere rating!
  4. Check the operation of the circuit. If the fuse blows again, look for the cause in the wiring or consumer.

Make sure the ignition is turned off|Inspect the fuse for melting|Check the rating of the new fuse|Exclude short circuit in the circuit-->

When replacing fuses in the engine compartment (for example, a fan or fuel pump relay), proceed with caution: moisture often accumulates here, which can lead to corrosion of the contacts. If you notice oxidation, clean the terminals special lubricant for electrical contacts (For example, Liqui Moly Electronic-Spray).

💡

If the fuse is stuck and cannot be pulled out, do not pull it with force - this could damage the seat. Instead, gently rock it from side to side or use a flathead screwdriver (not a metal one!).

How to diagnose a malfunction if the fuse is intact?

It happens that the circuit does not work, but the fuse appears to be working. In this case, the problem may lie in:

  • 🔌 Oxidized contacts — pull out the fuse and inspect the seat. If there is a green coating, clean it with an eraser or a special liquid.
  • 🔋 Faulty relay - for example, if the cooling fan does not work, check the relay K1 in the engine compartment. It often “jams” due to overheating.
  • 📉 Poor grounding - in Qashqai J10 weak points: grounding under the dashboard (passenger side) and the battery. Check the ground with a multimeter.
  • 🔧 Broken wiring - especially relevant for chains ABS and parking sensors. Wires often fray in the wheel arches.

If you suspect a relay, you can temporarily swap it with a known working one (for example, the fan relay and headlight relay are the same size). If after replacing the circuit works, the problem is in the relay.

⚠️ Attention! B Nissan Qashqai J10 with 2.0 MR20DE there is one feature: if it doesn’t work fuel pump, check not only the fuse F15 (15A), but also a relay K5 in the engine compartment. Often it “sticks” due to moisture, and the car does not start, although the fuse is intact.

What fuses and relays should I buy for replacement?

For Qashqai J10 standard fuses fit "Mini Blade" type (the most common). However, there are a few recommendations:

  • 🔹 Denomination - always take a fuse with the same ampere value as indicated on the diagram. For example, for a cigarette lighter it is 10A, for heating glass - 20A.
  • 🔹 Brand — it is better to choose trusted manufacturers: Hella, Bosch, Valeo or original Nissan (article 28500-JD00A for dialing). Avoid cheap Chinese analogues - they often melt at the slightest load.
  • 🔹 Relay - for critical circuits (starter, fuel pump), take a relay with sealed housing (For example, Hella 4RA 003 557-011). They last longer in high humidity conditions.

The cost of quality fuses is from 50 to 200 rubles per package (10 pcs.). Relays will cost 200–500 rubles per piece. Don't skimp on these parts: a faulty fuse or relay can cause fire in the cabin or breakdown of expensive equipment (For example, ECU).

💡

If the fuses of the same circuit are constantly burning in your Qashqai J10, the problem does not lie with them, but with a short circuit or overload. In this case, diagnostics of the wiring or consumer (for example, a radio or compressor) is required.

Frequently asked questions about fuse blocks Nissan Qashqai J10 2.0

Is it possible to install a larger fuse if it is constantly on?

No! It's dangerous. A fuse is designed for a specific load, and if it blows, there is a problem in the circuit (short circuit or overload). Installing a fuse with a large rating can lead to melted wiring or even a fire. Instead, find and fix the cause of the problem.

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

Most often this happens due to:

  1. Using powerful devices (for example, a car vacuum cleaner or inverter).
  2. Short circuit in the socket (check the contacts for melting).
  3. Problems with wiring (frayed or oxidized wire).

Try plugging the device into a different outlet (for example, in the trunk). If the fuse does not light, the problem is in the cigarette lighter.

Where can I find a fuse diagram for my configuration?

The diagram is usually printed on back of the fuse box cover. If it is missing or has been erased, download the instruction manual for your modification on the website Nissan (section Owners → Manuals). There are also diagrams on specialized forums, for example, Qashqai Club Russia.

How to check the relay in the engine compartment?

The easiest way is to swap a suspicious relay with a known working one (for example, a headlight relay). If the circuit works after replacement, the problem is in the relay. You can also check the relay with a multimeter:

  1. Set the multimeter to dial mode.
  2. Connect the probes to the contacts 85 And 86 (coil). There must be resistance 50–120 Ohm.
  3. Apply 12V voltage to the contacts 85 And 86 - a click should be heard (contacts closing 30 And 87).
What should I do if there is moisture in the fuse box?

Moisture in the fuse box is a serious problem and can lead to contact corrosion and short circuits. Proceed like this:

  1. Disconnect the battery.
  2. Dry the block with a hairdryer (cold air!) or napkins.
  3. Clean contacts from oxidation (use WD-40 or Liqui Moly Kontaktreiniger).
  4. Apply to contacts dielectric grease (For example, CRC 2-26).
  5. Check the integrity of the block seals - if they are torn, replace them.
