Quick answer
The 2019 Volvo VNR features multiple fuse box locations to protect its complex electrical systems. You'll find fuse boxes conveniently located under the hood, behind the passenger side kick panel (dashboard), and in the battery/storage compartment, typically near the frame rails or within a dedicated compartment.
Under-Hood Fuse Box
The under-hood fuse box, often located on the driver's side near the firewall or battery, houses fuses and relays for critical engine functions, lighting, and other high-current components. Always verify the exact fuse layout with the diagram printed on the inside of the fuse box cover, as configurations can vary slightly.

Trunk/Cargo Area Fuse Box (Battery Compartment)
The fuse box in the rear of the vehicle, often within or adjacent to the battery compartment (usually found on the frame rails or dedicated storage compartment), handles power distribution for trailer connections, certain body controllers, and other rear-mounted electrical accessories. Always refer to your VNR's specific fuse diagram for accurate information.

How to Test a Fuse
To test a fuse, you'll need a fuse puller (usually found in one of the fuse boxes) and a multimeter or a fuse tester. Here's a basic procedure:
- Locate the suspected fuse: Refer to the fuse box diagram to identify the fuse for the non-working component.
- Turn off the ignition: Ensure the vehicle is off to prevent electrical shock or damage.
- Remove the fuse: Use the fuse puller to carefully extract the fuse. Never use pliers or metal tools, as this can damage the fuse box or cause a short.
- Visually inspect: Many fuses have a visible wire inside. If this wire is broken or melted, the fuse is blown.
- Use a multimeter (for a more accurate test):
- Set your multimeter to the continuity setting (often indicated by a speaker icon).
- Touch the probes to the metal contact points on top of the fuse. If the multimeter beeps or shows a reading close to zero ohms, the fuse is good. If there's no reading or an
Before you pull a fuse on the 2019 Volvo VNR
- 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.
