Quick answer
The 2016 Volvo VNL has three primary fuse box locations:
- Under-hood: Located on the driver's side, near the firewall.
- Dashboard Kick-Panel (Driver's Side): Accessible by removing the kick panel below the steering column.
- Under the passenger seat (Sleeper Cab): For sleeper cab models, this fuse box is typically found beneath the passenger seat.
Under-hood Fuse Box
The under-hood fuse box houses fuses and relays for critical engine components and high-current systems. Always refer to the fuse legend inside the cover for the most accurate information as configurations can vary by trim and optional equipment.

|---|---|---|---|
| F1 | 20A | Yellow | ECM/PCM Main Power |
| F2 | 15A | Blue | Fuel Pump |
| F3 | 30A | Green | ABS Module Power |
| F4 | 25A | Clear | Ignition Coils/Ignition Relay |
| F5 | 10A | Red | Headlight (Low Beam, Left) |
| F6 | 10A | Red | Headlight (Low Beam, Right) |
| F7 | 15A | Blue | Headlight (High Beam, Left) |
| F8 | 15A | Blue | Headlight (High Beam, Right) |
| F9 | 40A | Green | Blower Motor |
| F10 | 20A | Yellow | A/C Clutch |
| F11 | 20A | Yellow | Starter Relay Supply |
| F12 | 15A | Blue | Trailer Brake Control |
| F13 | 10A Red | ECM/PCM Sensors | |

| F12 | 15A | Blue | HVAC Controls |
Under the Passenger Seat Fuse Box (Sleeper Cab)
For 2016 Volvo VNL models equipped with a sleeper cab, an additional fuse box is often located under the passenger seat. This box typically supplies power to the sleeper area amenities. Configurations can vary significantly, so always consult your owner's manual and the fuse box lid diagram.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F1 | 20A | Yellow | Sleeper Cab 12V Outlet (Rear) |
| F2 | 15A | Blue | Refrigerator/Cooler |
| F3 | 10A | Red | Sleeper Cab Interior Lights |
| F4 | 10A | Red | HVAC Bunk Controls |
| F5 | 20A | Yellow | Inverter (if equipped) |
| F6 | 15A | Blue | Auxiliary Power Unit (APU) Control |
| F7 | 10A | Red | TV/Entertainment System (Sleeper) |
| F8 | 15A | Blue | Microwave/Coffee Maker (if equipped) |
How to Test a Fuse
Testing a fuse is a straightforward process:
- Locate the fuse box: Refer to the Quick Answer section above.
- Identify the suspect fuse: Check the fuse box legend to find the fuse associated with the malfunctioning component.
- Visual inspection: Many fuses have a clear plastic body. Look for a broken wire or discoloration inside the fuse. A blown fuse will typically have a visible break in the metal strip.
- Use a fuse tester or multimeter: For a more accurate test, use a fuse tester (a small tool that lights up if the fuse is good) or a multimeter set to continuity mode. Touch the probes to the two test points on top of the fuse (or to each end of the fuse if removed). If the tester lights up or the multimeter beeps/shows continuity, the fuse is good. If not, the fuse is blown.
- Replace with the correct rating: Always replace a blown fuse with a new fuse of the exact same amperage (A) and type. Using a fuse with a higher amperage rating can lead to serious electrical damage or fire.
Common Blown Fuses on This Vehicle
Based on common issues and general truck usage, some fuses you might find yourself replacing more often on a 2016 Volvo VNL include:
- Cigar Lighter/12V Outlets (F2 in the Dash Kick-Panel box): These often blow due to over-current from charging multiple devices or using high-power accessories.
- What to check first: Disconnect all devices from the 12V outlets before replacing the fuse. Ensure no frayed wires or shorts in connected accessories.
- Headlight Fuses (F5-F8 in Under-hood box): Headlights can blow due to bulb failure, wiring issues, or simply age.
- What to check first: Inspect the headlight bulbs themselves. If a bulb is out, replacing it will often resolve the issue. Check for any visible damage to the headlight wiring.
- Trailer Brake Control (F12 in Under-hood box): Issues with trailer wiring or a short in the trailer
Before you pull a fuse on the 2016 Volvo VNL
- 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.
- Many heavy trucks have more than one power distribution point (cab, under-hood or near the batteries), and some circuits use circuit breakers instead of fuses. Some systems have 24-volt starting circuits; confirm the voltage before testing.
- Disconnect the battery before working near high-current fuses or cables.
