Quick answer
The 2016 Nissan Altima has three primary fuse box locations:
- Under-hood fuse and relay box: Located in the engine bay, near the battery on the driver's side.
- Driver-side interior fuse box: Located inside the cabin, under the dashboard to the left of the steering column, behind a small trim panel.
- Passenger-side interior fuse box: Located behind the glove box. You will need to open the glove box, empty it, and press the sides inward to release the stops and let it swing down completely to access this fuse panel.
Under-Hood Fuse & Relay Box Diagram
This main fuse box, often called the Intelligent Power Distribution Module (IPDM), is located in the engine compartment on the driver's side, just behind the battery. You'll need to remove the plastic cover to access the fuses and relays. The layout printed on the underside of the cover is your most accurate guide.

Relay Locations (Under-Hood)
- Starter Relay: Controls power to the starter motor.
- Fuel Pump Relay: Activates the fuel pump.
- A/C Relay: Engages the air conditioning compressor clutch.
- Headlight Relay: Controls power to the high and low beam headlights.
- ECM Relay: Provides main power to the engine computer.
Driver-Side Interior Fuse Box Diagram
This fuse box is located inside the vehicle, tucked under the dashboard to the left of the steering wheel. You may need to remove a small, marked plastic cover to see the fuses.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| 1 | 10A | Red | Airbag Module (SRS) |
| 2 | 10A | Red | Meter / Gauges, Warning Lamps |
| 6 | 10A | Red | Stop Lamps (Brake Lights) |
| 10 | 10A | Red | Park/Tail Lamps, License Plate Lights |
| 11 | 20A | Yellow | Front Wipers |
| 12 | 15A | Blue | Front 12V Power Outlet (Cigar Lighter style) |
| 13 | 15A | Blue | Audio / Radio / Infotainment Display |
| 14 | 10A | Red | Heated Mirrors (if equipped) |
| 15 | 10A | Red | Interior Room Lamps |
| 18 | 15A | Blue | Center Console 12V Power Outlet |
| 19 | 10A | Red | Ignition Switch Signal |
| 20 | 10A | Red | Turn Signal Lamps |
Note: Fuse numbers and circuits can vary slightly based on your vehicle's specific trim level and options. Always confirm with the diagram printed inside your fuse box cover.
Passenger-Side Interior Fuse Box (BCM) Diagram
This third fuse block is more hidden. It is located behind the glove compartment. To access it, open and empty the glove box, then push the retaining tabs on the sides inward, allowing the entire glove box to swing down and out of the way. This panel is often integrated with the Body Control Module (BCM).
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| 43 | 10A | Red | BCM (Body Control Module) |
| 48 | 10A | Red | Power Door Locks |
| 52 | 15A | Blue | Power Windows |
| 53 | 7.5A | Brown | Shift Lock Control Unit |
| 54 | 10A | Red | Push Button Ignition |
| 57 | 10A | Red | BCM Power |
How to Test a Fuse
Testing a fuse is a simple process. A "blown" fuse has a broken internal wire, interrupting the electrical circuit it was designed to protect.
- Visual Inspection: Pull the suspect fuse straight out of its slot (a fuse puller tool is often included in the fuse box, or use needle-nose pliers). Hold it up to the light. You should see a continuous S-shaped wire inside. If that wire is broken or looks burnt, the fuse is blown.
- Using a Multimeter: For a more definitive test, set a multimeter to the continuity setting (it often looks like a sound wave symbol). Touch one probe to each metal blade on the top of the fuse. If the multimeter beeps or reads close to zero ohms, the fuse is good. If it remains silent or reads "OL" (Open Line), the fuse is blown.
When replacing a fuse, always use a new one with the exact same amperage (Amp) rating. Using a higher-rated fuse can cause a fire hazard by allowing too much current through the circuit, damaging components and melting wires.
Common Blown Fuses on the 2016 Nissan Altima
- 12V Power Outlet / Cigar Lighter (Fuse #12 or #18): This is one of the most common fuses to blow. It often happens when a faulty phone charger or other accessory is plugged in. If your 12V outlet stops working, check these 15A fuses first. Also, check the plug-in device itself for damage.
- Audio / Radio (Fuse #13): If your radio or infotainment screen suddenly goes black and won't turn on, this 15A fuse in the driver-side interior box is the first place to look. This can sometimes blow during the installation of aftermarket audio equipment.
- Fuel Pump (Fuse #43, Under-Hood): If your Altima cranks but refuses to start, a blown fuel pump fuse could be the culprit. The engine isn't getting any gas. While replacing the fuse might get you started, a blown fuel pump fuse often indicates a failing fuel pump that is drawing too much current, so further diagnosis is recommended.
- Low Beam Headlights (Fuse #37 & #38, Under-Hood): If one of your low beams goes out and a new bulb doesn't fix it, the next logical step is to check the specific 15A fuse for that side. If both go out simultaneously, it could be the headlight relay.

Before you pull a fuse on the 2016 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.
