Check the power distribution layout inside the cabin and engine compartment first, as this crossover uses two separate panels with distinct assignments. The interior block sits beneath the dashboard near the driver’s knee area, while the under-hood box is mounted close to the battery. Each slot corresponds to a specific circuit such as lighting, climate control, audio system, or ignition components, and incorrect identification can lead to repeated faults or damage.
Pay attention to amperage ratings: small blade elements typically range from 10A to 20A for accessories, while higher loads like cooling fans or ABS modules rely on 30A–50A inserts. Replacing a burned element with a higher rating risks overheating the wiring harness. Factory labeling is often printed on the inner cover, but wear or missing lids makes a detailed layout reference necessary.
Focus on common failure points such as power windows, infotainment unit, and cigarette lighter socket–these circuits frequently trip due to overload or aging connectors. The electrical scheme for this mid-size SUV produced in the late 2000s groups related systems logically, which helps trace faults quickly when combined with a clear slot map and proper identification of relay positions.

Check the cabin power block under the dashboard on the driver’s side first; most electrical faults such as dead outlets, non-working interior lights, or inactive infotainment units trace back to this location. Use the label on the cover to match each circuit position with its function, then verify continuity with a multimeter rather than relying on visual inspection alone.
The engine bay distribution box handles high-load circuits including cooling fans, ignition, and charging system components. Access it near the battery, remove the protective lid, and identify relays and links assigned to major subsystems. For example, a failed cooling fan relay may mimic overheating issues, so testing relay operation by swapping with an identical unit can quickly isolate the problem.
Each circuit uses a color-coded blade element indicating amperage rating: typically red for 10A, blue for 15A, yellow for 20A, and green for 30A. Installing a higher-rated piece to “solve” repeated failures risks wiring damage and potential fire. Always replace with the exact rating specified in the panel legend.
If multiple accessories stop working at once, inspect shared power lines such as ACC or IGN circuits. These grouped feeds supply several components simultaneously, so one blown element can disable radio, power windows, and dashboard controls together. Cross-reference the panel chart to locate the shared slot and test it under load.
Corrosion inside the under-hood box can lead to intermittent contact. Remove each element one at a time, examine the terminals for oxidation, and clean lightly with electrical contact cleaner. Ensure the cover seal is intact to prevent moisture ingress, especially in humid or coastal climates.
When diagnosing a non-start condition, focus on ignition and fuel delivery circuits. Check the slots assigned to the starter control and fuel pump, then verify relay engagement by listening for a click while turning the key. Absence of sound often points to a failed relay or lack of control signal.
Use a wiring chart from the service manual to trace circuits beyond the panel itself. This helps identify downstream faults such as damaged harness sections or failed components that may repeatedly cause overload. Testing voltage at both sides of the element while the circuit is active provides a clear indication of current flow.
Keep spare blade elements of common ratings in the glove compartment along with a puller tool. Quick replacement on the road can restore critical functions like headlights or wipers without requiring towing or workshop intervention.
Exact Locations of Interior and Engine Bay Fuse Boxes in 2009 Nissan Murano
Open the driver’s door and look directly below the steering column to access the cabin electrical panel; it sits behind a small rectangular cover integrated into the lower dash trim, slightly left of the brake pedal. Pull the cover outward using the molded tab, and the panel will be exposed without tools. For quick identification, a label is printed on the inner side of the lid, showing circuit assignments and amperage values.
The interior block is mounted low and angled upward, which means visibility is limited unless you kneel outside the vehicle. Use a flashlight to clearly see the rows. This section typically handles lighting, audio system, climate controls, and accessory sockets.
- Position: under dashboard, driver side
- Access: removable plastic cover
- Orientation: tilted upward toward firewall
- Tools required: none
Under the hood, the main power distribution unit is placed near the battery on the right-hand side of the engine compartment (when facing the vehicle). It is enclosed in a black rectangular box with snap-lock clips. Release the clips by pressing inward and lifting the lid straight up; no screws are involved. The underside of this cover includes a clear layout indicating relay and circuit positions.
This engine bay unit controls high-load systems such as cooling fans, ignition components, ABS module, and charging system. Because of its proximity to heat and moisture, ensure the cover is securely resealed after inspection. Contacts should remain clean and dry to avoid intermittent faults.
Quick Location Summary
- Cabin panel: below steering wheel, left side, behind snap-off trim
- Engine compartment unit: adjacent to battery, right side, under clip-on lid
- Both covers include internal labeling for fast reference
- No specialized tools required for access
Access Tips
- Use a trim tool or fingers to avoid scratching panels
- Check labels inside covers before removing any component
- Work with ignition off to prevent electrical issues
- Keep spare inserts of matching amperage in the glove box
