Quick Answer
The 2025 Ram ProMaster typically features three main fuse box locations: under the hood, under the driver's side dashboard (kick panel), and potentially a third in the cargo area, depending on the specific trim and options.
Under-Hood Fuse Box
This fuse box is located in the engine compartment, usually near the battery on the driver's side. It houses fuses and relays for critical engine functions, lighting, and other high-current components.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F01 | 40A | Green | ABS Pump |
| F02 | 30A | Pink | PCM/ECM (Powertrain Control Module/Engine Control Module) |
| F03 | 25A | Natural | Fuel Pump Relay |
| F04 | 20A | Yellow | Ignition Coils / Injectors |
| F05 | 15A | Light Blue | Starter Relay |
| F06 | 20A | Yellow | Low Beam Headlights (Left) |
| F07 | 20A | Yellow | Low Beam Headlights (Right) |
| F08 | 15A | Light Blue | High Beam Headlights (Left) |
| F09 | 15A | Light Blue | High Beam Headlights (Right) |
| F10 | 10A | Red | Horn |
| F11 | 30A | Pink | Blower Motor |
| F12 | 10A | Red | A/C Clutch |
| F13 | 15A | Light Blue | Trailer Brake Controller (if equipped) |
| F14 | 20A | Yellow | Accessory Power Outlet (Under-hood) |
| F15 | 40A | Green | Main Power Distribution |
Relay Locations (Under-Hood):
- Fuel Pump Relay: Typically located near fuse F03.
- Starter Relay: Often near fuse F05.
- A/C Clutch Relay: Usually close to fuse F12.
- Headlight Relays (Low/High Beam): Often found in banks near their respective fuses.
Dash Fuse Box (Driver's Side Kick Panel)
This fuse box is typically found behind a removable panel on the driver's side dashboard, near the kick panel. It protects circuits for interior accessories, cabin lighting, and various control modules.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F01 | 10A | Red | Radio/Infotainment System |
| F02 | 15A | Light Blue | Interior Lights |
| F03 | 20A | Yellow | Cigar Lighter / 12V Power Outlet (Dash) |
| F04 | 10A | Red | ABS Module |
| F05 | 10A | Red | Airbag Control Module (ACM) |
| F06 | 7.5A | Brown | Instrument Cluster |
| F07 | 10A | Red | Power Windows |
| F08 | 10A | Red | Electric Mirrors |
| F09 | 15A | Light Blue | Wiper Motor |
| F10 | 10A | Red | Brake Switch |
| F11 | 5A | Tan | Tail Lights (Left) |
| F12 | 5A | Tan | Tail Lights (Right) |
| F13 | 10A | Red | Park Lights |
| F14 | 15A | Light Blue | Cabin Blower Motor Control (Lower Speeds) |
| F15 | 20A | Yellow | Accessory Power Outlet (Console) |
Cargo Area Fuse Box (If Equipped)
Some ProMaster configurations, especially those with upfitting packages or specific cargo area options, may include a supplementary fuse box in the rear of the vehicle. This is less common but worth checking if you experience issues with rear accessories.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F01 | 20A | Yellow | Rear Accessory Power Outlet |
| F02 | 15A | Light Blue | Rear Interior Lighting |
| F03 | 10A | Red | Trailer Wiring (Auxiliary) |
How to Test a Fuse
Testing a fuse is a straightforward process. You'll need a fuse puller (often found in the fuse box lid or with the vehicle's tools) and a multimeter or a fuse tester tool.
- Locate the Fuse: Identify the suspect fuse using the diagrams above and your vehicle's fuse box lid legend.
- Remove the Fuse: Carefully pull the fuse straight out of its slot using the fuse puller.
- Visual Inspection: Many fuses have a visible wire inside. If this wire is broken or melted, the fuse is blown. For opaque fuses, you'll need a tester.
- Test with a Multimeter: Set your multimeter to the continuity setting (often indicated by a speaker icon). Touch one probe to each metal blade of the fuse. If the multimeter beeps or shows a reading close to zero ohms, the fuse is good. If there
Before you pull a fuse on the 2025 Ram ProMaster
- 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.
