Quick answer
Your 2021 Jeep Cherokee has three primary fuse box locations:

Trunk/Cargo Area Fuse Box
Located on the driver's side of the cargo area, behind a removable access panel, this fuse box handles circuits for the rear of the vehicle.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F1 | 25A | Natural | Rear Defroster |
| F3 | 20A | Blue | Trailer Brake Controller |

How to test a fuse
- Turn off the ignition and all accessories.
- Locate the fuse box and remove the cover. You should see a diagram of the fuse layout.
- Identify the suspect fuse.
- Remove the fuse using the puller tool, often found in the fuse box itself.
- Visually inspect the fuse. A blown fuse will have a broken or melted metal strip inside.
- For a more accurate test, use a multimeter set to continuity. Touch the probes to each end of the fuse. A good fuse will show continuity (a reading near zero ohms or a beep), while a blown fuse will show an open circuit.
Common blown fuses on this vehicle
- Cigar Lighter / 12V Outlet Fuse: This is one of the most common fuses to blow. Often, a faulty phone charger or other device plugged into the outlet is the cause. Before replacing the fuse, unplug any devices and check the outlet for foreign objects.
- Radio / Infotainment Fuse: If your radio or touchscreen is dead, this fuse is the first thing to check. Electrical spikes or internal faults in the unit can cause it to blow.
- Trailer Light Fuses: If you tow a trailer, faulty trailer wiring is a frequent cause of blown fuses. Check the trailer's wiring harness for shorts or corrosion before replacing the fuse.
Note: Fuse locations and amperage can vary slightly based on your vehicle's specific trim level and options. Always consult the fuse diagram printed on the inside of your fuse box lid to confirm the correct fuse for the circuit in question.

Before you pull a fuse on the 2021 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.
