Quick Answer
On the 2018 Jeep Cherokee, you will find three main fuse box locations:
- Engine Compartment / Under-Hood Power Distribution Center: Located on the driver's side of the engine bay, near the battery.
- Interior Fuse Panel: Located under the dashboard on the driver's side, near the kick-panel.
- Rear Cargo Area / Trunk: Located in the left-side trim panel in the rear cargo area.
Under-Hood Power Distribution Center
This fuse box, often called the Power Distribution Center (PDC), contains high-amperage fuses and relays that control the primary power systems of your Cherokee. To access it, open the hood and locate the large black box on the driver's side of the engine compartment. Press the tabs on the lid to remove the cover.
Always disconnect the battery before servicing high-amperage fuses.

How to Test a Fuse
A blown fuse is a common cause of electrical problems. You can quickly check a fuse to see if it's the source of your issue.
- Turn Off the Ignition: Ensure the vehicle is off.
- Locate the Fuse: Find the suspect fuse in one of the panels listed above.
- Remove the Fuse: Use the fuse puller tool, often found in the fuse box lid, to gently pull the fuse straight out.
- Inspect the Fuse: Hold the fuse up to the light. Inside the plastic body, you will see a small metal strip. If this strip is broken or melted, the fuse is blown.
- Replace if Necessary: If the fuse is blown, replace it with a new fuse of the exact same amperage (Amp) rating. Using a fuse with a higher rating can cause a fire.
Common Blown Fuses on the 2018 Jeep Cherokee
- Power Outlet / Cigar Lighter (F81, F90): These are among the most common fuses to blow, often due to a faulty phone charger or other plugged-in device. If an outlet stops working, this fuse is the first thing to check. Unplug any devices before replacing the fuse.
- Fuel Pump (F13): If your Cherokee cranks but won't start, a blown fuel pump fuse could be the culprit. If this fuse blows repeatedly, it may indicate a problem with the fuel pump itself, which will require further diagnosis.
- Low-Beam Headlights (F40, F41): If a headlight goes out, it's usually the bulb. However, if replacing the bulb doesn't fix the issue, check the corresponding fuse. If both low-beams are out, a blown fuse or relay is a likely suspect.

Before you pull a fuse on the 2018 Jeep Cherokee
- 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.
