2020 Jeep Cherokee Fuse Box Diagram & Amperage Guide

Quick Answer

The 2020 Jeep Cherokee features multiple fuse box locations to protect its electrical systems. You'll find fuse boxes under the hood, behind the passenger side kick panel (dashboard), and in the rear cargo area.

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

The under-hood fuse box, also known as the Power Distribution Center (PDC), is located in the engine compartment, typically near the battery on the driver's side. This box houses larger fuses and relays for critical systems like the engine control module, fuel pump, ignition, starter, and major power distribution. Always consult the diagram on the fuse box lid for the most accurate information for your specific trim level.

Relays: The under-hood fuse box also contains several relays. Common relays include the Fuel Pump Relay, Starter Relay, ASD (Automatic Shut-Down) Relay, and various fan relays. Their exact positions can vary, so always refer to the diagram on your fuse box lid.

Passenger Side Kick Panel Fuse Box (Junction Block)

This fuse box, often referred to as the junction block, is located behind the passenger side kick panel, typically near the glove compartment or beneath the dashboard. It manages power for many interior accessories and modules.

Rear Cargo Area Fuse Box (Body Control Module/Auxiliary)

Some 2020 Jeep Cherokee models, particularly those with additional features or higher trim levels, may have an auxiliary fuse box located in the rear cargo area, often on the driver's side panel. This box typically handles power for specific rear-mounted accessories or features.

Note: Fuse configurations can vary slightly due to different trim levels, engine options, and optional equipment. Always refer to your vehicle's owner's manual and the fuse box lid diagrams for the exact layout and amperage ratings applicable to your specific 2020 Jeep Cherokee.

How to Test a Fuse

Testing a fuse is a straightforward process that can help you diagnose electrical issues. You'll need a fuse puller (usually found in one of the fuse boxes) and a multimeter or a fuse tester.

1. Locate the Fuse Box: Identify the fuse box related to the malfunctioning component.
2. Identify the Suspect Fuse: Consult the fuse diagram to find the fuse for the circuit you're investigating.
3. Turn Off the Vehicle: Ensure the ignition is off to prevent electrical shocks or damage.
4. Remove the Fuse: Use the fuse puller to carefully remove the suspect fuse. Always pull straight up to avoid bending the terminals.
5. Visually Inspect: Hold the fuse up to the light. If the metal wire or filament inside is broken or burnt, the fuse is blown and needs replacement.
6. Test with a Multimeter (for non-visible fuses):
   • Set your multimeter to the Ohms (Ω) setting, or continuity test setting.
   • Touch the multimeter probes to each metal terminal on top of the fuse.
   • A good fuse will show a reading close to zero ohms or emit a continuity beep. A blown fuse will show an open circuit (OL) or no beep.
7. Replace with Correct Fuse: If the fuse is blown, replace it with a new fuse of the exact same amperage (A) 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 circuits are prone to blowing more often due to usage or potential issues. If you experience one of these problems, check the corresponding fuse first:

• Cigar Lighter / 12V Power Outlets: These fuses (often F13 in the passenger kick panel or F18/F03 in other boxes) are frequently blown due to overloads from charging multiple devices or using high-power accessories. Check the device you plugged in first, as it might be drawing too much power.
• Blower Motor: If your climate control fan stops working, the blower motor fuse (F07 under the hood or F04 in the passenger kick panel for rear blower) is a common culprit. A failing blower motor itself can also cause this fuse to blow.
• Radio/Infotainment System: Issues with the radio or display often point to a blown infotainment fuse (F19 under the hood or F01 in the passenger kick panel). Before replacing, ensure no aftermarket accessories are causing a short.
• Headlights/Tail Lights: If only one headlight or a set of tail lights is out, check the specific fuse for that light (e.g., F09/F10 for low beams, F13/F14 for tail lights under the hood). If both are out, it might be a relay or a more general wiring issue.
• Trailer Tow Connectors: If you have a trailer package and experience issues with trailer lights or brakes, check the dedicated trailer fuses (F17 under the hood or F04 in the rear cargo area). Overloaded trailer wiring is a common cause.

Always check the printed legend on your fuse box lid and your owner's manual before making any fuse changes. Specific fuse locations and amperages can vary based on your vehicle's exact trim and options.
