Quick Answer
The 2019 Ram 3500 has three main fuse box locations:
- Under-hood: Integrated Power Module (IPM) / Totally Integrated Power Module (TIPM) on the driver's side, near the battery.
- Dash Panel (Passenger Side Kick Panel): Located on the passenger side, behind the kick panel.
- Rear Passenger Seat: Under the rear passenger seat.
Always consult the fuse box lid or your owner's manual for the most accurate and up-to-date fuse information specific to your vehicle's trim level and options, as configurations can vary.
Under-hood Fuse Box (Integrated Power Module - IPM/TIPM)
The under-hood fuse box, often referred to as the Integrated Power Module (IPM) or Totally Integrated Power Module (TIPM), is the primary power distribution center for your Ram 3500. It houses fuses and relays for critical engine, transmission, and major electrical systems.

Before you pull a fuse on the 2019 Ram 3500
- 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.
