Quick Answer
The 2023 Ford Ranger features three primary fuse box locations: under the hood in the engine compartment, behind the passenger kick panel in the cabin, and within the cargo area.
Under-Hood Fuse Box
The under-hood fuse box, also known as the Power Distribution Box, is located on the driver's side of the engine compartment, near the battery. It houses high-amperage fuses for major electrical components and relays for various systems.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F1 | 20A | Yellow | Powertrain Control Module (PCM)/Engine Control Module (ECM) |
| F2 | 10A | Red | PCM/ECM Ignition Feed |
| F3 | 30A | Green | Fuel Pump |
| F4 | 20A | Yellow | Ignition Coils/Ignition System |
| F5 | 40A | Green | Starter Relay |
| F6 | 15A | Blue | Low Beam Headlights - Right |
| F7 | 15A | Blue | Low Beam Headlights - Left |
| F8 | 20A | Yellow | High Beam Headlights - Right |
| F9 | 20A | Yellow | High Beam Headlights - Left |
| F10 | 10A | Red | Tail Lights/Parking Lights - Right |
| F11 | 10A Red | Tail Lights/Parking Lights - Left | |
| F12 | 20A | Yellow | Brake Light Switch |
| F13 | 40A | Green | Blower Motor |
| F14 | 10A | Red | A/C Clutch Relay |
| F15 | 30A | Green | Anti-lock Brake System (ABS) Pump |
| F16 | 10A | Red | ABS Module/Wheel Speed Sensors |
| F17 | 30A | Green | Trailer Brake Controller (if equipped) |
| F18 | 20A | Yellow | Power Steering Control Module |
| F19 | 15A | Blue | Horn |
| F20 | 25A | Clear | Wipers - Front |
Common Under-Hood Relays:
- R1 (Starter Relay): Engages the starter motor.
- R2 (Fuel Pump Relay): Powers the fuel pump.
- R3 (PCM Relay): Powers the Powertrain Control Module.
- R4 (A/C Clutch Relay): Engages the air conditioning compressor clutch.
- R5 (Headlight Relays - LH/RH High/Low Beam): Control power to the headlights.
Passenger Kick Panel Fuse Box
The smart junction box (SJB), also known as the passenger compartment fuse box, is located behind the passenger side kick panel. Remove the panel to access the fuses that protect various interior electrical components.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F21 | 10A | Red | Radio/Infotainment System |
| F22 | 15A | Blue | SYNC Module/USB Ports |
| F23 | 20A | Yellow | Cigar Lighter/12V Power Outlet - Front |
| F24 | 15A | Blue | Auxiliary Power Outlet - Rear (if equipped) |
| F25 | 10A | Red | Airbag Control Unit (ACU) |
| F26 | 10A | Red | Instrument Cluster |
| F27 | 10A | Red | Power Windows - Front |
| F28 | 10A | Red | Power Windows - Rear (if equipped) |
| F29 | 10A | Red | Moonroof (if equipped) |
| F30 | 10A | Red | Interior Cabin Lights |
| F31 | 15A | Blue | Door Lock Actuators |
| F32 | 7.5A | Brown | Heated Seats (if equipped) |
| F33 | 10A | Red | HVAC Control Module |
| F34 | 5A | Tan | Odometer/Diagnostic Port (OBD-II) |
| F35 | 10A | Red | Steering Wheel Controls |
Note: Specific fuse assignments in the passenger kick panel fuse box can vary slightly depending on the Ranger's trim level and optional equipment. Always consult the fuse diagram printed on the inside of your fuse box lid for the most accurate information.
Cargo Area Fuse Box
The 2023 Ford Ranger typically does not have a separate, dedicated fuse box in the cargo area. Any rear electrical components, such as those related to trailer towing or bed lighting, are usually fused through the under-hood power distribution box or the smart junction box. Some aftermarket accessories may have their own in-line fuses installed by the owner.
How to Test a Fuse
Testing a fuse is a straightforward process that can help you diagnose electrical issues:
- Locate the Fuse Box: Identify the fuse box related to the malfunctioning component.
- Identify the Suspect Fuse: Consult the fuse diagram on the fuse box lid or in your owner's manual to find the fuse for the circuit you're troubleshooting.
- Inspect Visually: A blown fuse often has a broken wire or melted metal inside. Some fuses have a small window to aid in visual inspection.
- Use a Fuse Tester or Multimeter: For a more definitive test, use a fuse tester (a simple tool that lights up when a fuse is good) or a multimeter set to continuity mode. Touch the probes to the metal contact points on top of the fuse. A good fuse will show continuity, while a blown fuse will not.
- Replace if Blown: If the fuse is blown, replace it with a new fuse of the exact same amperage rating and type. Never substitute a higher-amp fuse, as this can lead to serious electrical damage or fire.
Common Blown Fuses on This Vehicle
While any fuse can blow, some fuses are more prone to failure due to their function or the components they protect. On the 2023 Ford Ranger, commonly blown fuses might include:
- Cigar Lighter/12V Power Outlets (F23/F24): These fuses often blow due to overloading from charging multiple devices or using high-power accessories. If your phone charger or air compressor isn't working, check these first.
- Headlights (F6, F7, F8, F9): Headlight fuses can blow due to a short in the wiring, a faulty bulb (less common with modern LED headlights), or an electrical surge. If one or both of your headlights are out, check these fuses.
- Blower Motor (F13): A blower motor fuse can blow if the motor is working too hard (e.g., due to a clogged cabin air filter) or if there's an internal fault with the motor. If your A/C or heat fan isn't working, this is a good place to start.
- Trailer Brake Controller (F17): If you use a trailer frequently, issues with the trailer's wiring or a short in the trailer brake system can cause this fuse to blow.
What to Check First: Before assuming a blown fuse, consider recent activity. Did you plug in a new device? Did you experience an electrical flicker? These clues can help narrow down the culprit. Always double-check your owner's manual and the fuse box lid for the most accurate fuse locations and mappings for your specific trim level.

Before you pull a fuse on the 2023 Ford Ranger
- 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.
