Why You Need This Diagram

Think of the fuse box diagram as the Rosetta Stone of your car's electrical system. Without it, troubleshooting electrical problems is like groping in the dark. This diagram serves several crucial purposes:

Repairing Electrical Issues: If your headlights suddenly quit, your power windows stop working, or your radio goes silent, a blown fuse is often the culprit. The diagram pinpoint's the exact fuse to check.
Installing Aftermarket Accessories: Planning to add a killer sound system, a dashcam, or some sweet underglow lighting? The diagram helps you identify appropriate circuits to tap into safely, preventing overloads and potential damage.
Understanding Your Vehicle's Electrical System: Just knowing what each fuse protects gives you a deeper understanding of how your Murano's electrical system functions. This knowledge is invaluable for preventative maintenance and future troubleshooting.
Avoiding Costly Mechanic Visits: Many electrical problems are simple blown fuses. Knowing how to identify and replace them yourself saves time and money.

Key Specs and Main Parts of the 2016 Murano Fuse Box

The 2016 Nissan Murano, like most modern vehicles, features multiple fuse boxes. The two most important ones are typically located:

Inside the Cabin: Usually found on the driver's side, often tucked away behind a panel near the steering wheel or under the dashboard. This box primarily houses fuses for interior components like lights, the radio, power windows, and the climate control system.
Under the Hood (Engine Compartment): Typically located near the battery. This box handles fuses for critical engine components, headlights, ABS, and other high-current systems.

Here's a breakdown of the key parts you'll find in each fuse box:

Fuses: These are the sacrificial links in the circuit, designed to blow and interrupt the current flow if an overload occurs, protecting more expensive components. They are rated in Amps (A), indicating the maximum current they can handle. Common ratings include 5A, 7.5A, 10A, 15A, 20A, 25A, and 30A.
Relays: These are electromechanical switches that control high-current circuits using a low-current signal. They're used for components like headlights, the starter motor, and the fuel pump. You'll recognize them as small, cube-shaped components.
Fuse Box Cover: This cover usually has a diagram printed on its inside, which is a simplified version of the complete diagram. However, the complete diagram provides more detail.
Fuse Puller: A small plastic tool used to safely remove fuses without damaging them. Many fuse boxes have one integrated into the cover.

Decoding the Symbols: Understanding the Diagram

The fuse box diagram isn't just a random collection of lines and boxes. It's a carefully designed map of your car's electrical system. Let's break down the common symbols:

Lines: Lines represent electrical circuits. Thicker lines usually indicate circuits that carry higher currents.
Boxes: Boxes represent fuses or relays. The size of the box doesn't necessarily indicate the size of the fuse or relay.
Numbers: Numbers next to the boxes indicate the fuse number. This is critical for identifying the correct fuse.
Amperage Ratings: The amperage rating (e.g., 10A, 20A) is usually printed near the fuse box. This indicates the maximum current the fuse can handle. Always replace a blown fuse with one of the *same* amperage rating. Using a higher amperage fuse can cause serious damage.
Icons: Icons represent the component that the fuse protects. Common icons include a lightbulb (headlights, taillights), a steering wheel (power steering), a fan (cooling fan), a radio, and a window (power windows).
Colors: While not always consistent, sometimes the color of the wire associated with a fuse is indicated on the diagram. This can be helpful for tracing circuits.

Example Icon Interpretations:

A "headlight" icon signifies the fuse protecting the headlight circuit.
A "horn" icon indicates the fuse for the horn.
A "windshield wiper" icon indicates the fuse for the windshield wipers.

How It Works: Protecting the System

The principle is simple: Ohm's Law dictates that voltage (V) equals current (I) times resistance (R) (V = IR). A fuse is a deliberately weak point in a circuit with a specific resistance. When the current exceeds the fuse's rating (in Amps), the fuse's internal filament heats up rapidly and melts, breaking the circuit. This prevents excessive current from flowing to the protected component, which could cause overheating, damage, or even a fire.

Think of it like a dam. A dam is built to hold back a certain amount of water. If the water level exceeds the dam's capacity, the dam will break, preventing the entire valley from being flooded suddenly. The fuse is the dam in the electrical circuit.

Real-World Use: Basic Troubleshooting

Let's say your 2016 Murano's power windows suddenly stop working. Here's how to troubleshoot using the fuse box diagram:

Consult the Diagram: Locate the fuse box diagram. Figure out which fuse box controls the power windows (usually the one inside the cabin).
Identify the Fuse: Look for the icon that represents power windows (often a picture of a window) and note the fuse number and amperage rating.
Locate the Fuse: Open the fuse box and find the fuse with the corresponding number.
Inspect the Fuse: Carefully remove the fuse using the fuse puller. Examine the filament inside the fuse. If the filament is broken, the fuse is blown.
Replace the Fuse: Replace the blown fuse with a new fuse of the same amperage rating.
Test: Turn on the ignition and test the power windows. If they work, you've solved the problem. If the new fuse blows immediately, there's likely a short circuit in the power window circuit. This requires more in-depth troubleshooting.

Important troubleshooting tips:

Always disconnect the negative terminal of the battery before working on the electrical system, especially when dealing with high-current circuits.
Use a multimeter to check for continuity in a fuse. A multimeter provides a more reliable test than visual inspection.
If a fuse blows repeatedly, there's a short circuit or an overload in the circuit. Don't keep replacing the fuse without investigating the underlying problem.

Safety First: Risky Components

Working with your car's electrical system can be dangerous. Here are some components to be extra careful around:

Airbag System: Fuses related to the airbag system are extremely sensitive. Incorrect handling can cause accidental airbag deployment, resulting in serious injury. If you suspect an airbag issue, consult a qualified technician.
ABS (Anti-lock Braking System): ABS relies on complex electrical circuits. Tampering with these circuits can compromise the braking system's integrity.
ECU (Engine Control Unit): The ECU is the brain of your engine. Incorrect modifications or repairs can damage the ECU, leading to serious engine problems.
High-Current Fuses (Under the Hood): These fuses protect critical engine components. A short circuit in these circuits can result in a fire.

Warning: Never bypass a fuse with a wire or other conductive material. This eliminates the protection the fuse provides and can cause severe damage or a fire.

Remember: If you're uncomfortable working on any part of your car's electrical system, especially those mentioned above, it's always best to consult a qualified mechanic.
