Owners Nissan Murano Z50 (2015–2026) sooner or later face the need to check or replace fuses. Failure of headlights, non-functioning windows, problems with the audio system - all this can be due to a blown fuse. But where to look for the blocks, how to open them and which fuse is responsible for a specific function? In this article you will find detailed diagrams with decoding, photo of the location of the blocks, as well as tips for diagnostics and replacement.

We analyzed the technical documentation Murano Z50 for different markets (USA, Europe, Russia) and identified key differences in the layout of fuse blocks. We paid special attention common problemsproblems that owners face: for example, why the cigarette lighter fuse blows or how to protect electronics from power surges. At the end of the article there are answers to popular questions and unique fuse compatibility table for different modifications Murano Z50.

Where are the fuse boxes located in the Nissan Murano Z50?

B Nissan Murano Z50 provided two main fuse boxes:

  • 🔧 Main unit in the cabin — located to the left of the steering column, behind the protective cover. Access to it opens by turning three clamps.
  • 🚗 Additional block under the hood — located next to the battery, in a plastic box with the inscription FUSE & RELAY BOX.

In some configurations (for example, with a system ProPILOT Assist) may be present third block — it is located behind the glove compartment and is responsible for additional electronics. Its availability depends on the year of manufacture and market of the vehicle. For example, in US models this block is found more often than in European versions.

To avoid confusion, remember a simple rule: all fuses related to comfort (lights, multimedia, power windows) are located in the cabin, and those responsible for the “power” part (starter, generator, fans) are under the hood.

Engine compartment fuse box: decoding and nuances

Block under the hood Nissan Murano Z50 contains power group of fuses and relaysresponsible for critical systems. Its location is next to the battery, under a plastic cover with the inscription FUSE & RELAY. The peculiarity of this block: fuses of the type are used here MAXI (large size) and standard mini.

Important point: in models with V6 3.5L (QR25DE) and 2.5L hybrid (e-POWER) schemes are different. For example, the hybrid version adds a fuse IGCT (120A), responsible for the inverter. Below is a universal diagram for gasoline versions:

  • 🔋 30A (MAXI) — Main relay of the injection system (EFI RELAY). If it fails, the engine will not start.
  • 💡 15A (mini) — Low beam (left headlight). The right headlight uses a separate fuse.
  • 50A (MAXI) — Electric cooling fan. If it burns out, check the temperature sensor.
  • 🔌 100A (mega fuse) — Main fuse for the generator circuit. Requires replacement only during service.

B Murano Z50 2022–2026 a relay for the system appeared in the engine compartment ProPILOT Park (automatic parking). It is located next to fuse #22 (10A) and is marked as IPAS. If this circuit malfunctions, an error light appears on the dashboard C1A99.

What should I do if the fuse blows again?

If the new fuse blows immediately after replacement, this indicates a short circuit in the circuit. Required:

1. Disconnect all consumers connected to this circuit (for example, a cigarette lighter).

2. Test the wiring with a multimeter in resistance testing mode.

3. Pay attention to traces of melting on the contacts of the unit - this is a sign of overheating.

In 80% of cases, the problem lies in damaged wire insulation or a faulty consumer (for example, a stove fan).

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

Replacing the fuse in Nissan Murano Z50 does not require special skills, but there are nuances that will help you avoid mistakes. Follow this algorithm:

  1. Turn off the power. Remove the key from the ignition and open the driver's door (this will discharge the capacitors in the system).
  2. Find the faulty fuse. Use the diagram from the previous sections or the user manual. B Murano Z50 There is a sticker on the cover of the block with the purpose of the fuses, but it is often erased.
  3. Remove the fuse. Use the plastic tweezers that came with the car. If it is not there, you can carefully pry the fuse off with a flathead screwdriver.
  4. Check integrity. A blown fuse has a broken thread inside. For accurate diagnostics, use a multimeter in calls.

When installing a new fuse, make sure it is the denomination is the same with the original. For example, if you insert a 25A fuse instead of 15A into socket No. 7 (cigarette lighter), this may lead to the contacts of the unit melting. B Murano Z50 2019+ included SL/Platinum Color coded fuses are used:

  • 🟢 Green — 30A
  • 🔴 Red — 10A
  • 🔵 Blue — 15A
  • 🟡 Yellow — 20A
⚠️ Attention: If the fuse blows again after replacement, do not repeat installation - this may indicate a short circuit in the circuit. B Murano Z50 A common cause of this is damage to the wiring harness in the door openings (especially on the driver's side). Check the corrugation for kinks.

Before replacing a fuse, take a photo of its location in the block with your phone. This will help avoid confusion if you remove several pieces to check.

Common problems and their solutions

Analysis of owner forums Nissan Murano Z50 showed that some fuses fail more often than others. Here are the most common cases and ways to eliminate them:

1. The cigarette lighter fuse blows (No. 7, 15A/20A)

Reasons:

  • 🔌 Using powerful devices (for example, a car vacuum cleaner or compressor).
  • 🔋 Short circuit in the 12V socket (often due to liquid ingress).
  • 📱 Low-quality chargers for phones with “jumping” voltage.

Solution: Replace the fuse with an original one (part number 28370-3M00A for 15A or 28370-4M00A for 20A). If the problem persists, check the outlet with a multimeter: resistance between +12V And mass must be infinite.

2. Power windows do not work (fuse No. 18, 20A)

Reasons:

  • ❄️ Freezing of the mechanism in winter (especially relevant for rear windows).
  • ⚙️ Wear of the gear motor (characteristic grinding noise during operation).
  • 🔌 Oxidation of contacts in the fuse box.

Solution: Before replacing the fuse, try manually lowering/raising the window (to prevent mechanical blocking). If the fuse blows repeatedly, check the motors on all doors - even if only one power window is not working, the problem may be in the parallel circuit.

3. Low beam fails (fuses No. 5 and No. 6, 15A)

Reasons:

  • 💡 The lamp has burned out (in Murano Z50 halogen ones are used H11 or LED modules).
  • 🌧️ Moisture gets into the headlight (often after washing under high pressure).
  • 🔌 Short circuit in the wiring harness to the headlight.

Solution: Replace both bulbs (even if one is burned out) as they wear out at the same time. If the fuse blows again, unplug the headlight connector and check the circuit for a short circuit.

💡

In 90% of cases, blown fuses in the Murano Z50 are not due to their “natural” wear and tear, but to problems in the circuit: short circuit, overload or consumer failure. Always look for the root cause!

Where to buy fuses for Nissan Murano Z50?

Original fuses for Murano Z50 can be purchased from official dealers Nissan (items are listed in the previous section), but their prices are often inflated. Alternative options:

  • 🛒 Auto stores: Fuses of standard ratings (10A, 15A, 20A) are sold at any auto parts store (for example, AutoDetail, existential). The main thing is to choose a quality brand, e.g. Hella or Bosch.
  • 🌍 Online: On AliExpress or Wildberries You can find fuse kits with tweezers (search for “fuse kit Nissan”). Cost - from 200 rubles.
  • 🔧 Service centers: If you need a rare rating (for example, 120A for hybrid versions), order through Nissan Parts or from trusted suppliers such as Amayama.

Important: avoid cheap fuses without markings. B Murano Z50 fuses are used low internal resistance, and low-quality analogues may overheat, which will lead to melting of the block. Original fuses Nissan are marked Genuine Nissan Fuse on the body.

For hybrid versions (e-POWER) special fuses are required for high voltage circuits. They can only be ordered through a dealer using the following article numbers:

  • 28550-4M00A — inverter fuse (120A).
  • 28370-AL50A — charging circuit fuse (30A).

Tips for the prevention and care of the fuse box

To keep the fuses in Nissan Murano Z50 last longer, follow these recommendations:

  1. Regular cleaning of contacts. Once a year, remove the block covers and clean the contacts from oxidation using WD-40 Contact Cleaner or isopropyl alcohol. This is especially true for vehicles operated in high humidity conditions.
  2. Checking wiring harnesses. Inspect the corrugations in the doorways and under the hood for cracks. IN Murano Z50 The weak point is the harness going to the back door - it often frays.
  3. Use of voltage stabilizers. If you often connect powerful devices (for example, a refrigerator or inverter), install an additional stabilizer in the cigarette lighter circuit. This will protect fuse No. 7 from overload.
  4. Diagnostics at the first sign of a malfunction. If you notice that the fuse has begun to melt (dark spots appear on the body), immediately look for the cause - this is a sign of overheating of the circuit.

Owners Murano Z50 with the system ProPILOT It is recommended to carry out once every 2 years relay unit diagnosticslocated under the glove compartment. Dust and moisture can cause corrosion of the contacts, which will lead to false activation of the driver assistance system.

💡

If you have a long trip, carry a set of spare fuses (10A, 15A, 20A) and tweezers with you. B Murano Z50 The fuse blocks are reliable, but breakdowns often occur on the road, especially when using additional equipment.

FAQ: Frequently asked questions about Nissan Murano Z50 fuses

🔍 Why does my 2020 Murano Z50 have a 20A cigarette lighter fuse but the manual says 15A?
