2019 Jeep Grand Cherokee Fuse Box Diagram

Quick answer

The 2019 Jeep Grand Cherokee has two primary fuse box locations:

• Power Distribution Center (Under Hood): Located in the engine bay, on the passenger's side near the battery. This box contains high-amperage fuses and relays for major vehicle systems.
• Interior Fuse Panel (Passenger Kick Panel/Glove Box): Located behind a trim panel in the passenger footwell, to the right of the glove box. This box contains fuses for most interior and body-related components.

Under-Hood Power Distribution Center

This main fuse block manages the high-power systems of your Grand Cherokee, including the engine, starter, fuel system, and cooling fans. To access it, open the hood and locate the black rectangular box on the passenger side. Release the clips to remove the cover. The fuse and relay layout is printed on the inside of the lid—always verify your specific vehicle's layout against this guide.

Common Relays:

• Starter Relay: Controls power to the starter motor.
• Fuel Pump Relay: Activates the fuel pump.
• A/C Clutch Relay: Engages the air conditioning compressor.
• Blower Motor Relay: Controls the main power for the interior fan.

Interior Fuse Panel (Passenger Kick Panel)

This fuse panel is responsible for most of the electronics inside your cabin, including the radio, power outlets, and lighting. To access it, you will need to open the passenger door and remove the trim panel located on the side of the dashboard/kick panel area, to the right of the glove box.

Note: Fuse numbers, amperage, and the circuits they protect can vary based on your vehicle's specific trim level and options (e.g., V6 vs. V8, towing package, premium audio). Always consult the diagram printed on your vehicle's fuse box cover to confirm the exact layout.

How to Test a Fuse

Testing a fuse is a simple process. A "blown" fuse is a safety device that has intentionally broken an electrical circuit due to an overcurrent. You can check a fuse in two ways:

1. Visual Inspection: Pull the suspect fuse from its slot using a fuse puller (often found in the fuse box cover). Hold it up to the light. Inside the colored plastic body, you will see a small metal strip. If this strip is intact, the fuse is good. If the strip is broken or appears burnt, the fuse is blown and must be replaced.
2. Multimeter Test: For a more definitive test, set a multimeter to the continuity setting (it looks like a sound wave symbol). Touch the probes to the two metal blades on top of the fuse. If the meter beeps or reads close to zero ohms, the fuse is good. If it remains silent or reads "OL" (Open Line), the fuse is blown.

When replacing a fuse, always use a new fuse with the exact same amperage rating. Using a higher-rated fuse can cause severe damage to the electrical system and create a fire hazard.

Common Blown Fuses on this Vehicle

• Blown 12V Power Outlet / Cigar Lighter Fuse (F22/F23): This is one of the most common issues, often caused by a faulty phone charger, a coin falling into the socket, or a defective device. If this fuse blows, first inspect the socket for any foreign objects. Unplug any chargers or accessories before replacing the fuse.

• Blown Fuel Pump Fuse (F11): If your Grand Cherokee cranks but won't start, the fuel pump fuse is a primary suspect. A blown fuse here could indicate a failing fuel pump that is drawing too much current. If a new fuse blows immediately or soon after, the fuel pump likely needs to be inspected by a professional.

• Blown Trailer Light Fuse (F10/F88): If you use your Grand Cherokee for towing, these fuses can blow due to faulty trailer wiring. Shorts in the trailer's wiring harness are the most common cause. Before replacing the fuse, inspect the trailer plug and wiring for any corrosion, frayed wires, or damage.

If a fuse blows repeatedly, it signals an underlying electrical problem that needs to be diagnosed and repaired.
