Nissan Murano Z50 (2008–2014 model year) is a reliable crossover, but even it periodically blows fuses. If your cigarette lighter doesn't work, your headlights fail, or your center console stops opening, the problem most likely lies in a blown fuse. In this article we will look at where the fuse boxes are located in Murano Z50, how to replace them correctly and what ratings to use so as not to burn the electronics.
We have collected current diagrams for all modifications (including hybrid versions and models with Bose-audio system), and also added unique data on fuses, which often fail due to the design features of the Z50. For example, why is the fuse F30 (10A) burns out when connecting gadgets to a USB port and how to fix it without a trip to the service center.
Where are the fuse boxes located in Nissan Murano Z50
B Murano Z50 There are two main fuse blocks:
- 🔧 Salon block — located to the left of the steering column, under the plastic cover. To gain access, pull the tab at the bottom of the panel.
- 🚗 Engine compartment block — located next to the battery, under the black plastic cover. Snaps on and can be removed without tools.
Additionally, in the trunk (behind the trim on the right side) there may be a relay block for systems AWD And VDC, but in most trim levels it is missing. If your Murano equipped panoramic roof or seat ventilation, look for a separate mini fuse box under the rear row of seats.
Important: on models with hybrid installation (For example, Murano Hybrid for the Japanese market) a third block has been added in the engine compartment - high voltage. Its fuses (usually 150A–200A) touch without special preparation prohibited!

Diagram and decoding of the cabin unit fuses
The cabin unit contains fuses for most consumers: lighting, audio system, climate control and interior electronics. Below is the current diagram for Murano Z50 2008–2014 (including 2011 restyling).
| Designation | Rating (A) | What is he responsible for? | Notes |
|---|---|---|---|
F2 |
10 | Audio system (Bose), navigation | Often burns out when there is a short circuit in the speakers |
F10 |
15 | Cigarette lighter, 12V socket | Burns out when connecting powerful inverters (>150W) |
F15 |
10 | USB port, Aux-entrance |
Problems with F15 - check the charging cable |
F20 |
7.5 | Dashboard lighting | If it burns out, check the incandescent lamps |
F30 |
10 | Body control unit (BCM) |
Burns out when the alarm is connected incorrectly |
Please note: on models with leather interior and heated seats added fuse F25 (20A) — he is responsible for heating the front seats. If heating only works on one side, also check the relay K5 in the engine compartment.
⚠️ Attention: fuseF10 (15A)for cigarette lighter in Murano Z50 often replaced by20Aor25A, but this leads to melting of the socket contacts. If you need more power, install an additional outlet with a separate fuse.
Engine compartment fuse box: what you need to know
The engine compartment is responsible for critical systems: starter, generator, cooling fans And ABS. Here fuses of increased rating are used - from 20A to 100A.
Features of the engine compartment Murano Z50:
- 🔥 Fuse
F1 (100A)- main, responsible for the generator circuit. If it burns out, the car will not start. - ⚡ Fuse
F10 (30A)- nourishesECU(engine control unit). If it fails, the engine stalls or does not start. - 💡 Fuse
F15 (20A)- controls the headlights. If burnt out, check the bulbs for short circuits.
On models with xenon headlights fuse added F20 (15A) for the ignition unit. If one headlight does not turn on, but the lamp is intact, either this fuse or the relay is to blame K3.
☑️ Checking the engine compartment fuse box
Important: if the fuse in the engine compartment has burned out F5 (50A) (responsible for ABS/VDC), do not rush to change it. First, check the wheel sensors for breaks - these are often what cause a short circuit.
How to correctly replace a fuse in Murano Z50
Replacing a fuse seems like a simple procedure, but... Murano Z50 there are nuances. For example, if you incorrectly remove the fuse from the interior block, you can damage the plastic guides, which will lead to poor contact.
Step by step instructions:
- Turn off the ignition and remove the negative terminal from the battery (required for the engine compartment unit!).
- Locate the blown fuse (the jumper inside is broken or melted).
- Use the special tweezers included in the kit Murano (found in the glove compartment) or plastic pliers to remove the fuse. Do not use metal tools!
- Install a new fuse same denomination. Increasing the amperage is fraught with fire!
- Check the system operation. If the fuse blows again, look for a short circuit.
Advice: in Murano Z50 Interior fuses sometimes “stick” to the contacts due to oxidation. If the fuse does not come out, do not apply force - spray WD-40 to contacts and wait 5 minutes.
Before replacing the fuse F30 (10A) (body control unit) reset errors using a scanner ELM327. Sometimes a fuse blows due to stuck errors in BCM, and not due to an actual malfunction.
Which fuses are most likely to blow? Murano Z50
Analysis of owner forums Murano Z50 shows that the following fuses most often fail:
| fuse | Cause of combustion | How to prevent |
|---|---|---|
F10 (15A) (cigarette lighter) |
Connecting powerful devices (vacuum cleaner, compressor) | Use a socket with a separate fuse |
F15 (10A) (USB/ Aux) |
Poor quality charging cables | Check cables for short circuits |
F30 (10A) (BCM) |
Incorrect alarm connection | Install alarms from official dealers |
F2 (10A) (audio system) |
Short circuit in speakers Bose | Check the integrity of the speaker wiring |
Interesting fact: on models with American equipment (For example, Murano LE AWD) fuse F10 for the cigarette lighter has a nominal value 20A, not 15A, as in European versions. This is due to the fact that in the USA they often use powerful inverters for laptops.
⚠️ Attention: If in your Murano Z50 after replacing the fuseF2 (10A)(audio system) navigation stopped working, but the radio works - the problem is not in the fuse, but in the control unitAV. The unit needs to be re-flashed or replaced.
How to choose quality replacement fuses
Not all fuses are created equal. B Murano Z50 It is recommended to use original fuses Nissan (article 28550-JA00A for mini-fuses) or high-quality analogues:
- 🔹 Littlefuse - the best price/quality ratio, used on the assembly line of many automakers.
- 🔹 Bussmann — premium segment, can withstand power surges.
- 🔹 Hella - a good choice for high rated fuses (
80A–100A).
Avoid cheap fuses without markings - they may have a too low cross section, which will lead to false operation. Also, do not buy fuses that say "FUSE"instead of the face value, it's a fake.
For fuses 100A–150A (For example, F1 in the engine compartment) use only original Nissan or Bussmann ATP. These fuses have a special anti-corrosion coating that prevents contact oxidation.
How to spot a fake fuse?
Counterfeit fuses often have jagged edges, dull metal color, and lack of rating markings on the body. Original Littlefuse or Bussmann always laser marked.
Common mistakes when working with fuses
Even experienced car owners sometimes make mistakes that lead to serious damage. Here are the most common:
- 🔌 Replacing with a fuse of a higher rating - for example,
15Ainstead of10A. This could fry the wiring! - 🔧 Using "bugs" (homemade wire jumpers). B Murano Z50 this often causes the fuse box to fire.
- 💡 Ignoring the cause of combustion. If the fuse is blown, there is a problem in the circuit (short circuit, overload). A simple replacement will not solve the problem.
- 🔋 Working under voltage. Always disconnect the negative battery terminal before replacing fuses in the engine compartment.
It is especially dangerous to replace fuses in circuits ABS And Airbag. For example, if a fuse in the engine compartment has burned out F20 (10A) (responsible for airbags), do not install a fuse instead of it. 15A. This can lead to the airbags not deploying in the event of an accident!
If the system does not work after replacing the fuse, check the relay in the same block. B Murano Z50 relays often “stick” due to contact oxidation.
FAQ: Frequently asked questions about fuses Nissan Murano Z50
Can fuses from other cars be used?
Yes, if they meet the standard ISO 8820-3 (mini fuses) or ISO 8820-5 (maxi fuses). The main thing is that the denomination and size match. For example, fuses Toyota or Honda will fit if they are original Littlefuse.
Why after replacing the fuse F10 (cigarette lighter) did it burn out again?
Most likely there is a short circuit in the circuit. Common reasons:
- Damaged insulation of the wire going to the cigarette lighter.
- Oxidation of the contacts of a 12V socket (especially if powerful devices were connected there).
- Malfunction of the cigarette lighter itself (short circuit inside).
Check the circuit with a multimeter in "continuity" mode.
Where to find a fuse diagram for your modification Murano Z50?
Schemes differ depending on the year of manufacture and configuration. The exact diagram can be found:
- B instruction manual (pages 8-12 - section "
Fuses"). - On the cover of the fuse box (usually there is a sticker with a decoding).
- On the website Nissan TechInfo (subscription required).
For Murano Hybrid Schemes are available only at dealerships.
What to do if the fuse is intact, but the system does not work?
Possible reasons:
- Faulty relay in the same block (check for a click when turned on).
- Fuse or connector contacts are oxidized (clean
WD-40). - The problem is in the device itself (for example, a lamp or control unit has burned out).
- Broken wire in the circuit (check with a multimeter).
Can I add a fuse myself for new equipment (for example, a rear view camera)?
Yes, but you need to follow the rules:
- Connect only through a separate fuse (calculate the rating using the formula:
I = P/12, whereP— device power in watts). - Use free slots in the cabin unit (for example,
F35orF40- usually reserve). - Do not connect powerful consumers (for example, a subwoofer) directly to the cigarette lighter circuit - this will lead to combustion
F10.
It is best to run a separate line from the battery through the fuse and relay.
