2025 Jeep Wrangler – Fuse Box Diagram & Amperage

Quick Answer

The 2025 Jeep Wrangler typically has three main fuse box locations: under the hood, under the dashboard (driver's side kick panel), and in the cargo area.

Under-hood Fuse Box (Power Distribution Center)

This fuse box is located in the engine compartment, usually on the driver's side, near the battery. It contains many of the larger fuses and relays for critical vehicle systems.

Relay Locations (Under-hood):

• R1: Starter Relay
• R2: Fuel Pump Relay
• R3: Run/Accessory Relay
• R4: A/C Clutch Relay
• R5: Headlight Low Beam Relay
• R6: Headlight High Beam Relay
• R7: Blower Motor Relay
• R8: Horn Relay

Instrument Panel Fuse Box (Driver's Side Kick Panel)

This fuse box is located behind a panel on the driver's side, usually near the left kick panel or under the steering column. It primarily handles interior electrical components.

Cargo Area Fuse Box

Some 2025 Jeep Wrangler models, especially those with additional features or premium packages, may have a smaller fuse box in the rear cargo area. This is often designated for accessories, power outlets, or specific rear-mounted modules.

How to Test a Fuse

1. Locate the Fuse Box: Refer to the "Quick Answer" section for your vehicle's fuse box locations.
2. Identify the Suspect Fuse: Your vehicle's owner's manual or the fuse box lid will have a diagram indicating which fuse protects which circuit. Many fuses are color-coded by amperage. Always verify the printed legend in the fuse box lid, as configurations can vary based on trim and options.
3. Visual Inspection: Pull the suspected fuse straight out. Most modern fuses have a translucent plastic body. Look for a broken wire or melted metal strip inside the fuse. If it's broken, the fuse is blown.
4. Using a Multimeter (for more accurate testing):
   • Set your multimeter to the continuity or ohm setting.
   • Touch one probe to each metal terminal on top of the fuse (or the fuse's exposed metal blades if removed). A good fuse will show continuity (a beep or a reading close to zero ohms). A blown fuse will show no continuity or an "open" circuit reading.
5. Replace with Correct Amperage: If blown, replace the fuse with a new one of the exact same amperage rating and physical size. Using a fuse with a higher amperage can cause severe electrical damage or even a fire.

Common Blown Fuses on This Vehicle

Due to the varied nature of vehicle usage, certain fuses tend to blow more often. On a 2025 Jeep Wrangler, common culprits can include:

• Cigar Lighter/12V Power Outlets (F31, F32, F50): These often blow due to overcurrent from charging multiple devices, using high-power accessories, or a foreign object shorting out the socket. Check the device you were using when the fuse blew first.
• Radio/Infotainment (F30): While less common, issues with aftermarket installations, short circuits within the unit, or excessive current draw can cause this fuse to blow. If the fuse blows immediately upon replacement, there's likely a short in the circuit.
• Blower Motor (F03): Constant use, especially on high settings, or a failing blower motor itself can lead to this fuse blowing. If your blower fan suddenly stops working, check this fuse first.
• Headlights (F08, F09, F10, F11): A short in the headlight assembly or wiring, or a failing bulb, can cause headlight fuses to blow. If one headlight is out, but the bulb looks good, check its corresponding fuse.
• Trailer Brake (F13, F51): If your Wrangler is equipped with a trailer brake controller, issues with trailer wiring, a short in the trailer's electrical system, or an internal fault in the controller can cause these fuses to blow. Always inspect your trailer's wiring if this fuse blows.

What to Check First: Before replacing any fuse, try to identify the cause of the blown fuse. If you simply replace it without addressing the underlying issue, the new fuse will likely blow again. Disconnect any recently connected accessories from power outlets and inspect wiring for any visible damage.
