Note: Fuse assignments and amp ratings can vary slightly between trim levels (e.g., S, SV, SL, SR). Always confirm by checking the fuse diagram printed on the inside of the fuse box cover or in your owner's manual.
How to test a fuse
A blown fuse is easy to spot. The small metal filament inside the plastic housing will be broken.
- Turn off the ignition and all accessories.
- Locate the fuse box and remove the cover.
- Find the suspect fuse. The diagram on the cover will help you identify it.
- Use a fuse puller (often included in the fuse box) or a pair of small pliers to gently remove the fuse.
- Visually inspect the fuse. Look at the metal wire inside. If it's broken or melted, the fuse is blown.
- Use a multimeter (optional): For a more definitive test, set your multimeter to the continuity setting. Touch the probes to each of the fuse's metal tabs. If the multimeter beeps or shows a reading of zero, the fuse is good. If it doesn't, the fuse is blown.
- Replace the blown fuse with a new one of the exact same amperage rating. Using a higher amp fuse can cause a fire.
Common blown fuses on this vehicle
- Power Sockets (Cigar Lighter): This is one of the most common blown fuses, often caused by a faulty phone charger or other plug-in accessory. Check the accessory you were using for damage before replacing the 15A fuse.
- Audio/Infotainment: If your radio suddenly dies, the fuse is the first thing to check. This can happen randomly, but sometimes it's triggered by a faulty aftermarket sound system component.
- Low Beam Headlights: Headlight fuses can blow due to age or a power surge. If one headlight is out, check the bulb first. If the bulb is good, check the corresponding left or right headlight fuse in the under-hood fuse box. If both are out, the relay could be the issue.
If a fuse blows repeatedly, it indicates an underlying electrical problem that needs to be diagnosed by a professional. Don't keep replacing the fuse.

Before you pull a fuse on the 2017 Nissan Altima
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
