Quick answer
The 2019 Ram 1500 has two primary fuse box locations:
- Under-hood Power Distribution Center: Located in the engine compartment, near the battery on the driver's side.
- Interior Fuse Box: Located under the driver's side of the dashboard, near the steering column. You may need to remove a trim panel to access it.
Under-hood Power Distribution Center
This fuse box contains high-amperage fuses and relays that control major vehicle systems. The layout can vary slightly based on your truck's engine and trim level (e.g., eTorque hybrid system, trailer tow package). Always confirm the fuse locations and ratings with the diagram printed on the underside of the fuse box lid.

How to test a fuse
A blown fuse is a common and easy-to-fix issue. You can identify a bad fuse with a visual inspection or a multimeter.
- Safety First: Turn the ignition off and remove the key.
- Locate and Remove: Open the correct fuse box and use the fuse puller tool (often found clipped inside the box) to gently pull the suspect fuse straight out of its slot.
- Visual Inspection: Hold the fuse up to the light. Inside the plastic body, you will see a small metal strip. If this strip is broken or melted, the fuse is blown and needs to be replaced.
- Multimeter Test (for certainty): Set your multimeter to the continuity setting (it often has a symbol that looks like a sound wave). 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" (overload), the fuse is blown.
- Replacement: Replace the blown fuse with a new one of the exact same amperage rating. Using a fuse with a higher rating can cause severe damage to the electrical system and create a fire hazard.
Common blown fuses on this vehicle
- 12V Power Outlet / Cigar Lighter (F83, F51): This is one of the most common blown fuses. It often happens when a faulty phone charger or other accessory is plugged in. Before replacing the fuse, unplug everything from the power outlets and inspect them for foreign objects like coins or debris that could be causing a short circuit.
- Trailer Tow Fuses (F61, F62): If your trailer lights or trailer brakes aren't working, check these fuses first. The issue is often caused by faulty wiring on the trailer itself. A short in the trailer's wiring harness can instantly blow these fuses when you connect it to the truck.
- Fuel Pump Fuse (F20): If your Ram 1500 cranks but won't start, the fuel pump fuse is a good place to begin your diagnosis. If this fuse is blown, it could indicate a problem with the fuel pump itself or the wiring leading to it.
If a fuse blows repeatedly, it signifies an underlying electrical problem that needs to be properly diagnosed. Constantly replacing fuses without fixing the root cause can lead to more significant issues.

Before you pull a fuse on the 2019 Ram 1500
- 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.
