The fuse box, nestled within your vehicle’s electrical system, acts like a safeguard, protecting delicate circuits from overloads and preventing potential fires. By understanding how fuses work and how to decipher the fuse box diagram, you can diagnose and fix common electrical problems within your Murano, saving yourself time, money, and potential headaches.
Understanding the Basics: Fuses and Relays
Fuse Fundamentals
Fuses are essentially safety devices designed to interrupt an electrical circuit when the current flowing through them exceeds a specific threshold. Imagine them like tiny sacrificial lambs, burning themselves out to protect the rest of the system. These little heroes come in various amperage ratings, each capable of handling a different level of current. When a fuse blows, it creates an open circuit, effectively cutting off the flow of electricity to protect your valuable electrical components.
Relays: The Electrical Proxies
Relays act as electrical messengers, connecting power to various components within your Murano. Think of them as the switchboard operators of the automotive world. They receive a signal from a control unit (like the ignition switch) and then use their magnetic capabilities to close a circuit, allowing power to flow to the intended component. Relays are often used for high-power components like headlights, windshield wipers, and electric fans, preventing direct electrical strain on the control unit.

The 2007 Nissan Murano Fuse Box Diagram: Your Troubleshooting Toolkit
Location, Location, Location: Finding the Fuse Box
The 2007 Murano features two primary fuse boxes: one located in the engine compartment and the other nestled inside the dashboard. The engine compartment fuse box, often referred to as the “underhood fuse box,” is usually near the battery, while the interior fuse box is typically found behind the glovebox. To access the interior fuse box, you’ll need to remove the glovebox panel, often secured by a few clips or screws.
Deciphering the Diagram: A Visual Guide to the Fuse Box
The fuse box diagram is your roadmap to understanding the layout and functionalities. This diagram, often found in the owner’s manual or available online, depicts the physical arrangement of the fuses and relays within the box. It’s crucial to familiarize yourself with the diagram before tackling any fuse-related troubleshooting, as it reveals the purpose of each fuse and its corresponding circuit.
Identifying Fuses and Relays: The Legend
The diagram provides a legend that translates each numbered fuse or relay to its function. It will list components like headlights, radio, power windows, and more, correlated with specific fuses within the box. This legend is your key to pinpointing the fuse responsible for a particular electrical malfunction.
Troubleshooting Electrical Issues Using the Diagram
1. Isolate the Problem: Identify the Affected Circuit
Start by pinpointing the malfunctioning electrical component. Is it a headlight, a power window, or perhaps the audio system? Understanding the affected circuit is the first step in identifying the culprit fuse or relay.
2. Consult the Fuse Box Diagram: Map the Fuse or Relay
Once you’ve identified the faulty circuit, locate the corresponding fuse or relay on the diagram. The legend will tell you which fuse number or relay position governs that specific component.
3. Visually Inspect the Fuse: The Tell-Tale Signs
Carefully examine the fuse identified on the diagram. A blown fuse will typically show visible signs of damage, such as a melted or broken wire. Be cautious when handling fuses, as they can be hot after blowing.
4. Test Continuity: Using a Multimeter for Verification
To confirm the fuse’s condition, you can use a multimeter. Set the multimeter to the continuity function and touch the probes to the two ends of the fuse. If the fuse is good, the multimeter will beep, indicating a complete circuit.
5. Replace the Fuse: Restoring Electrical Flow
If the fuse is indeed blown (or you’re uncertain), replace it with a new fuse of the same amperage. Make sure the new fuse is identical in size and rating to the old one. Never use a fuse with a higher amperage, as this could damage other electrical components.
6. Relay Inspection: Checking for Proper Function
If the fuse appears to be intact, the issue might lie within a relay. Relays can malfunction or become stuck, preventing the intended component from receiving power. To test a relay, use a multimeter to check for continuity across its terminals.
Additional Safety Tips
Always remember to disconnect the battery before working on any electrical components, including the fuse box. This precaution helps prevent electrical shocks and potential damage to your vehicle’s electrical system. Also, ensure your hands are dry when handling fuses and relays to minimize the risk of electrical shock.
