2022 Jeep Cherokee Fuse Box Diagram & Amperage

Quick Answer

The 2022 Jeep Cherokee features three main fuse box locations: the Power Distribution Center (PDC) under the hood, the Instrument Panel (IP) fuse box in the passenger footwell, and the Rear Cargo fuse box in the rear cargo area.

Under-Hood Power Distribution Center (PDC)

The Power Distribution Center (PDC) is located in the engine compartment, typically near the battery. It houses many of the larger fuses and relays for critical systems such as the powertrain, anti-lock brakes, and cooling fans. Always refer to the fuse layout diagram on the underside of the PDC cover for the most accurate information for your specific trim level, as some variations may occur.

Relay Locations (PDC):

The PDC also houses several relays essential for various system operations. These include, but are not limited to:

• Fuel Pump Relay: Controls power to the fuel pump.
• Starter Relay: Engages the starter motor.
• Cooling Fan Relays (Low/High Speed): Operates the engine cooling fans.
• Headlight Relays (Low/High Beam): Controls power to the respective headlight circuits.
• A/C Clutch Relay: Engages the air conditioning compressor clutch.
• Ignition Relay: Powers various ignition-related components.

Instrument Panel (IP) Fuse Box

The Instrument Panel (IP) fuse box is located on the passenger side of the cabin, behind a removable panel on the kick panel. This fuse box typically contains fuses for interior accessories, comfort features, and various electronic modules. Always check the diagram on the back of the panel or in your owner’s manual for precise fuse identification.

Rear Cargo Fuse Box

Some 2022 Jeep Cherokee models, particularly those with additional features or higher trim levels, may have a third fuse box located in the rear cargo area, often behind a trim panel or under the cargo floor. This box typically handles power for rear accessories, power liftgate (if equipped), and trailer-related circuits.

Relays (Rear Cargo):

Relays in this box are typically for systems such as the power liftgate or trailer tow functionalities.

How to Test a Fuse

Testing a fuse is a straightforward process and requires a simple tool: a fuse tester or a multimeter. Here's how you do it:

1. Locate the Fuse: Identify the suspect fuse using the fuse box diagram.
2. Visual Inspection: Many fuses have a visible wire inside. If this wire is broken or melted, the fuse is blown. However, not all blown fuses are visually obvious.
3. Using a Fuse Tester (Light-Up Type): Insert the probe of the tester onto one metal contact point on top of the fuse, and connect the other lead to a good ground point. If the light illuminates, the fuse is good. Then test the other metal contact point. If the light only illuminates on one side, or not at all, the fuse is blown. For fuses in a circuit that is currently powered (e.g., ignition on), you can often test across the two small metal prongs on the top of the fuse. If the light lights up, the fuse is good.
4. Using a Multimeter: Set your multimeter to the continuity or ohms setting. Remove the fuse from its slot. 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 (the multimeter may beep). If it shows infinite resistance (OL or "open line") or no continuity, the fuse is blown.
5. Replace with Correct Amperage: Always replace a blown fuse with a new one of the exact same amperage (A) and type. Using a fuse with a higher amperage can lead to electrical system damage or fire.

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more commonly affected due to their circuits' usage or design. On the 2022 Jeep Cherokee, frequently encountered blown fuses often involve:

• Cigar Lighter / 12V Outlets (F02 IP Fuse Box): These fuses are often blown due to overcurrent from charging multiple devices or using high-power accessories. If your phone isn't charging or your accessories aren't working, check this first.
• Radio / Infotainment System (F01 IP Fuse Box, F19 PDC): Issues with the radio, Uconnect screen, or sound system can often be traced back to these fuses. Try a soft reset of the Uconnect system first, then check these fuses.
• Blower Motor (F05 PDC): If your HVAC fan isn't working on any setting, this is a prime suspect. A failing blower motor or a restricted cabin air filter can cause the fuse to blow.
• Headlights / Tail Lights (F08-F15 PDC): While less common with modern LED lighting, issues with individual lights not working should prompt a check of these fuses before assuming a bulb issue.
• Power Windows (F03 IP Fuse Box): If one or more power windows stop working, this fuse is a common culprit.

What to Check First: Before replacing a fuse, consider what might have caused it to blow. If a fuse repeatedly blows, there's an underlying electrical issue that needs professional diagnosis. Simply replacing it will not solve the root cause.
