2024 Jeep Grand Cherokee Fuse Box Diagram & Amperage

Quick answer: 2024 Jeep Grand Cherokee Fuse Box Locations

If you are looking to check a blown fuse on your 2024 Jeep Grand Cherokee (WL generation), there are two primary fuse box locations you need to know:

1. Under-Hood Power Distribution Center (PDC): Located in the engine compartment on the passenger side, near the battery jump-start terminals.
2. Interior Fuse Panel: Located under the driver’s side dashboard, behind the lower kick panel or access door.

Disclaimer: The following tables represent the most common configurations for the 2024 Jeep Grand Cherokee. Depending on your exact trim level (Laredo, Limited, Overland, Summit, 4xe PHEV) and optional equipment (like trailer tow packages or premium audio), some fuse locations and amperages may vary. Always verify against the printed legend located on the inside of the fuse box lid.

Under-Hood Power Distribution Center (PDC)

The under-hood fuse box handles the high-draw circuits and major powertrain components.

Relay Note: The under-hood PDC also houses several micro and mini relays. Common relays include the Starter Relay, Fuel Pump Relay, A/C Clutch Relay, and Cooling Fan Relays. The layout is stamped on the inside of the PDC cover.

Interior Fuse Panel (Driver Side Dash)

The interior fuse box primarily protects cabin electronics, infotainment, and convenience features.

How to test a fuse

Testing a fuse on your 2024 Grand Cherokee is a straightforward process, but doing it correctly will save you a lot of diagnostic time. Here is how an ASE-certified master technician approaches it:

1. Visual Inspection: Pull the suspected fuse using a fuse puller (usually provided inside the under-hood PDC lid). Hold it up to a bright light. Look at the U-shaped wire inside the plastic housing. If the wire is broken, melted, or blackened, the fuse is blown.
2. Test Light Method (Best for installed fuses): You don't always need to pull a fuse to test it. Turn the ignition to the "ON" position (do not start the engine). Connect the ground clip of an automotive test light to a solid, bare metal chassis ground. Probe the two tiny metal testing tabs on the top of the fuse. If the test light illuminates on both sides, the fuse is good. If it lights up on one side but not the other, the fuse is blown. If neither side lights up, the circuit isn't receiving power at all (check your ignition state or upstream relays).
3. Multimeter Continuity Test: Set your digital multimeter to the "Continuity" setting (the one that beeps). Pull the fuse out and touch one probe to each leg of the fuse. A continuous beep means the fuse is good. No beep means the circuit is open and the fuse must be replaced.

Important: Always replace a blown fuse with one of the exact same amperage and color. Never put a 30-amp fuse in a 10-amp slot. Doing so removes the circuit protection and can cause wiring harnesses to melt or even start an electrical fire.

Common blown fuses on this vehicle

While the 2024 Jeep Grand Cherokee is packed with robust modern electronics, certain circuits are more prone to blowing fuses due to wear and tear, aftermarket accessories, or external conditions.

• 12V Power Outlets / Cigar Lighter (F51 / F52): This is the most common blown fuse. Usually, this happens when a faulty phone charger, a high-draw tire inflator, or an inverter is plugged into the console or cargo area. What to check first: Inspect the 12V socket for coins, debris, or a defective accessory before replacing the fuse.
• Trailer Tow / Brake Control Fuses (F08 / F26): If you tow frequently, you might experience issues here. A short in the trailer's wiring harness (very common on older boat trailers) will instantly pop the Jeep's trailer circuit fuses. What to check first: Inspect the 7-pin or 4-pin trailer connector for corrosion, and test the trailer's wiring for shorts to ground.
• Radio / Uconnect Infotainment (F55): If your center touchscreen goes completely black and unresponsive, this fuse may have popped. Occasionally, a software glitch or a shorted USB cable connected to the media hub can overload this circuit. What to check first: Unplug all USB devices and inspect the ports for physical damage.
• Fuel Pump Motor (F05): A blown fuel pump fuse will result in a crank, no-start condition. What to check first: If this fuse repeatedly blows, it often indicates a failing fuel pump drawing too much amperage, or chafed wiring leading to the fuel tank.

If you keep blowing the same fuse, do not keep replacing it. A repeatedly blowing fuse is a symptom of a larger electrical short or failing component.
