Nissan Murano Z52 is a premium crossover that combines comfort, technology and reliability. However, even in such a car, problems with electrical equipment periodically arise, and most often the cause of this is burnt-out fuses. If your headlights don't work, your audio system fails, or your windows stop opening, the first thing to do is check your fuse box.
In this article you will find complete layout of fuses and relays for Murano Z52 (including restyled versions 2018 and 2021), their purpose, as well as step-by-step instructions for replacement. We will look at where the main blocks are located, how to correctly diagnose a fault, and which fuses most often fail. We will pay special attention hidden fuse box under the hood, which many owners are not even aware of.
Where are the fuse boxes located in Nissan Murano Z52
B Murano Z52 provided three main fuse boxes:
- 🚗 Salon block — located to the left of the steering column, behind the plastic cover. This is where the fuses for most of the interior systems (audio, climate control, instrument panel) are located.
- 🔧 Engine compartment block — located next to the battery, under the black plastic cover. Responsible for external lighting, starter, generator and other power circuits.
- 🔌 Additional relay block — hidden under the instrument panel on the passenger side (accessible only after removing the glove compartment). Relays for comfort and safety systems are located here.
The most popular - salon unit, since this is where fuses most often blow due to short circuits in multimedia or electric drive circuits. The engine compartment unit rarely causes problems, but checking it is mandatory if there is a malfunction of the starter, generator or external lighting.
⚠️ Attention: Do not confuse the fuse box with the relay box! Relays are responsible for switching powerful circuits (for example, a cooling fan or fuel pump), and fuses protect against overloads. B Murano Z52 relays often fail due to oxidation of the contacts - they can be cleaned, not just replaced.

Engine compartment fuse box: what you need to know
Engine compartment block Nissan Murano Z52 is responsible for power circuits car: starter, generator, external lighting, cooling fans and fuel pump. It is located next to the battery and is covered with a black plastic cover with the inscription FUSE & RELAY BOX.
Features of this block:
- ⚡ High denominations - fuses of 30A, 40A and even 100A are used here (for example, for a generator circuit).
- 🔥 Common problems — oxidation of contacts due to moisture (especially in rainy weather).
- 🚨 Critical circuits - a faulty fuse here may make it impossible to start the engine.
The most vulnerable fuses in the engine compartment:
| Fuse no. | Rating (A) | Purpose |
|---|---|---|
| F30 | 30A | Radiator cooling fan |
| F35 | 10A | Engine control unit (ECU) |
| F40 | 40A | Generator |
| F45 | 15A | Headlights (low/high beam) |
If your Murano Z52 won't start, first check the fuse F35 (10A) - he is responsible for nutrition ECU. Also pay attention to the relay R12 (fuel pump relay), which often sticks due to overheating.
⚠️ Attention: When replacing fuses in the engine compartment be sure to disconnect the battery (negative terminal first!). The contacts here carry high voltage, and a short circuit can damage the vehicle's electronics.
How to properly check and replace a fuse
Replacing the fuse in Nissan Murano Z52 - a simple procedure, but requiring accuracy. Here are the step-by-step instructions:
Turn off the ignition and turn off all electrical appliances
Find the faulty fuse (use the diagram from the manual)
Remove the fuse using special tweezers (included with the machine)
Check the fuse for continuity (visually or with a multimeter)
Install a new fuse of the same rating
Check the operation of the circuit-->
To check the fuse you can use:
- 👁️ Visual inspection - a blown fuse has a broken thread inside.
- 📊 Multimeter — set the circuit continuity check mode (buzzer). If the fuse is good, the device will beep.
- 💡 Test lamp - connect one end to ground, and touch the fuse terminals with the other. If the lamp does not light on one of the terminals, the fuse has blown.
If the fuse blows immediately after replacement, this means that there is short circuit. In this case:
- Check wiring for damage (especially at kinks or near moving parts).
- Turn off all consumers on the circuit (for example, if the cigarette lighter fuse blows, unplug all devices from the outlet).
- If the problem persists, contact the service for diagnostics using a scanner Nissan CONSULT.
What to do if you don't have fuse tweezers?
If you don’t have special tweezers at hand, you can carefully remove the fuse using small pliers or even your fingers (if the fuse is conveniently located). The main thing is not to use excessive force so as not to damage the contacts in the block.
Frequent problems with fuses in Murano Z52 and their solutions
Owners Nissan Murano Z52 often encounter typical faults related to fuses. Here are the most common cases and how to fix them:
