2015 Jeep Wrangler Fuse Box Diagram & Amperage

Quick Answer

The 2015 Jeep Wrangler typically has two main fuse box locations: one under the hood and another inside the cabin, usually behind the passenger kick panel. Some specialty trims or aftermarket additions might have additional fuse boxes, but these are the primary two you'll encounter.

Under-Hood Fuse Box (Power Distribution Center - PDC)

The Power Distribution Center (PDC) is located in the engine compartment, on the passenger side, near the battery. It contains various fuses and relays for critical engine functions, lighting, and other high-power accessories. Always verify the printed legend on the fuse box lid, as variations can occur based on trim level and specific options.

Relay Locations (Under-Hood PDC):

The PDC also houses several relays. While individual relay identification may vary slightly, common relays include:

• Fuel Pump Relay: Controls power to the fuel pump.
• Starter Relay: Energizes the starter motor.
• High Beam Headlight Relays: Separate relays for left and right high beams.
• Low Beam Headlight Relays: Separate relays for left and right low beams.
• Blower Motor Relay: Supplies power to the HVAC blower motor.
• A/C Clutch Relay: Engages the air conditioning compressor clutch.
• Horn Relay: Activates the horn.

Interior Fuse Box (Passenger Cabin)

The interior fuse box is typically located behind the passenger kick panel, near the glove compartment. To access it, you'll usually need to remove a plastic trim panel. This fuse box primarily handles power for various interior accessories, comfort features, and some control modules.

How to Test a Fuse

If an electrical component in your 2015 Jeep Wrangler isn't working, the first thing to check is often a fuse. Here's how to test one:

1. Locate the Fuse Box: Refer to the above sections to find the relevant fuse box.
2. Identify the Suspect Fuse: Consult your owner's manual or the fuse box lid diagram to identify the fuse protecting the non-functioning component.
3. Visual Inspection: Most modern fuses have a small wire visible through a clear plastic body. If this wire is broken or melted, the fuse is blown. However, sometimes a blown fuse isn't visually obvious.
4. Use a Fuse Tester or Multimeter:
   • Fuse Tester: These inexpensive tools light up if a fuse is good. Simply touch the tester probes to the two small metal test points on the top of the fuse while it's still installed. If both sides light up, the fuse is good. If only one side lights up or neither does, the fuse is likely blown.
   • Multimeter: Set your multimeter to the continuity or ohms setting. Remove the suspect fuse from its holder. Touch the multimeter probes to each metal blade of the fuse. A good fuse will show very low resistance (close to 0 ohms) or indicate continuity. A blown fuse will show an open circuit or infinite resistance.
5. Replace if Blown: If the fuse is blown, replace it with a new fuse of the exact same amperage (AMP) rating and type. Never use a fuse with a higher amperage rating, as this can lead to serious electrical damage or fire.

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more prone to failure due to their circuit's demands or their location. On a 2015 Jeep Wrangler, common fuses that might blow include:

• Cigar Lighter / 12V Outlets (M02, F21, F22): These often blow when accessories with high power draw are plugged in, or if there's a short circuit from a faulty charger or device.
  • What to check first: Unplug all devices from the outlets and replace the fuse. If it blows again immediately, there might be a wiring issue or a short in the outlet itself.
• Blower Motor (F03): If your HVAC fan stops working on all speeds, this fuse is a prime suspect.
  • What to check first: Ensure nothing is obstructing the blower motor and that the motor isn't making strange noises (indicating it might be failing and drawing too much current).
• Radio/Infotainment (F20, M01): If your radio suddenly goes dead, check these fuses.
  • What to check first: See if other electrical components are working. Sometimes aftermarket radio installations can cause issues.
• Headlights (F06, F07, F08, F09): If one or both headlights stop working, confirm that it's not just a burnt-out bulb before checking the fuses.
  • What to check first: Visually inspect the headlight bulbs. If the filaments appear intact, then check the fuses.
• Trailer Tow (F14, M19): If you're experiencing issues with your trailer lights or brakes, these fuses are often the culprit, especially if there's a short in the trailer wiring.
  • What to check first: Inspect your trailer's wiring for any damage or exposed wires that could be causing a short circuit.

Always remember to consult your 2015 Jeep Wrangler's owner's manual for the most accurate and detailed fuse box information, as fuse assignments can sometimes vary slightly between trim levels and specific vehicle configurations.
