2014 Nissan Altima Fuse Box Diagram – Every Fuse Explained
Owning a 2014 Nissan Altima is a reliable experience, but even the most dependable vehicles can experience electrical hiccups. A blown fuse is a common culprit, often leading to non-functioning components like headlights, power windows, or your radio. When these issues arise, knowing your way around the fuse box is crucial. This comprehensive guide provides the 2014 Nissan Altima fuse box diagram and details, helping you diagnose and resolve electrical problems quickly and efficiently. We’ll cover both the interior and engine compartment fuse boxes, providing a clear understanding of each fuse’s function.
Understanding Your 2014 Nissan Altima Fuse Boxes
The 2014 Nissan Altima typically has two main fuse boxes:
- Interior Fuse Box (Junction Box): Located inside the vehicle, usually under the dashboard on the driver’s side. This box protects components like the interior lights, radio, power windows, and other in-cabin electronics.
- Engine Compartment Fuse Box (IPDM E/R - Intelligent Power Distribution Module Engine Room): Situated in the engine bay, often near the battery. This box protects essential engine components, headlights, horn, and other vital systems.
Before diving into the fuse diagram, remember these important safety precautions:
- Always disconnect the negative (-) battery terminal before working on the fuse boxes. This prevents accidental short circuits.
- Use the correct amperage fuse when replacing a blown fuse. Using a fuse with a higher rating can damage the protected circuit and potentially cause a fire.
- Consult your owner’s manual for the most accurate and up-to-date information. The diagram provided here is a general guide, and minor variations may exist.
- If you’re uncomfortable working with electrical components, consult a qualified mechanic.

Troubleshooting Tips
- Identify the Problem: Determine which component is malfunctioning (e.g., headlights, radio, power windows).
- Locate the Fuse: Refer to the fuse box diagram in your owner’s manual to find the fuse related to the malfunctioning component.
- Inspect the Fuse: Use a fuse puller (often included in the fuse box cover) to remove the fuse. Visually inspect the fuse; if the metal wire inside is broken, the fuse is blown. You can also use a multimeter to test for continuity.
- Replace the Fuse: Replace the blown fuse with a new fuse of the same amperage.
- Test the Component: Turn on the component to see if it is functioning correctly.
- Repeat if Necessary: If the new fuse blows immediately, there might be a short circuit or a more significant electrical problem. Seek professional help.
