How to test a fuse
- Turn off the ignition and all accessories.
- Locate the fuse box.
- Remove the fuse with a fuse puller.
- Inspect the fuse. A good fuse will have an unbroken wire inside. A blown fuse will have a broken wire or a black smudge inside.
- Replace a blown fuse with a new fuse of the same amperage.
Common blown fuses on this vehicle
- Cigar lighter fuse: This is a common fuse to blow, especially if you use a lot of high-powered accessories. If this fuse blows, check the accessory that was plugged in at the time.
- Fuel pump fuse: This fuse can blow if there is a problem with the fuel pump or the fuel pump relay. If this fuse blows, the engine will not start.
- Headlight fuse: This fuse can blow if there is a problem with the headlight bulb or the headlight wiring. If this fuse blows, one or both of the headlights will not work.
Note: This information is for general guidance only. Always consult your owner's manual for the specific fuse diagram for your vehicle.

Before you pull a fuse on the 2015 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.
