2017 Jeep Grand Cherokee Fuse Box Diagram & Amperage

Quick answer

The 2017 Jeep Grand Cherokee has three main fuse box locations:

• Under-hood: Located in the engine compartment, on the passenger side.
• Instrument Panel (Dash) Fuse Box: Located on the passenger side kick panel.
• Rear Cargo Fuse Box: Located in the rear cargo area, behind a panel on the driver's side.

Under-Hood Fuse Box

The under-hood fuse box, also known as the Power Distribution Center (PDC), is located in the engine compartment on the passenger side, near the battery. This box contains high-current fuses and relays for major electrical components.

Under-Hood Relays:

• RL1: Starter Relay
• RL2: Fuel Pump Relay
• RL3: A/C Clutch Relay
• RL4: Radiator Fan Relay
• RL5: Headlight Low Beam Relay
• RL6: Headlight High Beam Relay

Instrument Panel (Dash) Fuse Box

The instrument panel fuse box is located on the passenger side kick panel. To access it, you'll need to open the passenger door and gently pry off the cover. This box typically houses fuses for interior electrical components and accessories.

Rear Cargo Fuse Box

The rear cargo fuse box is located in the rear cargo area, typically behind a removable panel on the driver's side. This fuse box often handles power for rear accessories and any factory-installed trailer wiring.

How to Test a Fuse

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

1. Safety First: Ensure the ignition is off and the vehicle is not running. If testing a fuse in the under-hood box, it's a good idea to disconnect the negative battery terminal, especially for high-amperage fuses.
2. Locate the Fuse: Identify the fuse you suspect is blown using the diagrams above and your vehicle's fuse box legend.
3. 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.
4. Use a Fuse Tester: A dedicated fuse tester lights up when a fuse is good. Simply touch the probes to the small metal test points on the top of the fuse. If it doesn't light up, the fuse is blown.
5. Use a Multimeter:
   • Set your multimeter to the continuity setting (usually indicated by a symbol that looks like a sound wave or diode). Some multimeters will beep when there's continuity.
   • Carefully remove the fuse from its slot using a fuse puller (usually found in your fuse box lid or with your vehicle's tools).
   • Touch one probe of the multimeter to each metal blade of the fuse.
   • If the multimeter beeps or shows a reading close to zero ohms, the fuse is good. If it shows "OL" (open loop) or no reading, the fuse is blown.
6. Replace the Fuse: If the fuse is blown, replace it with a new fuse of the exact same amperage rating and type. Using a fuse with a higher amperage can cause serious electrical damage or fire.

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more prone to failure due to the circuits they protect or common usage patterns. On the 2017 Jeep Grand Cherokee, some commonly blown fuses include:

• Cigar Lighter / 12V Power Outlets (F35, F50): These fuses often blow due to overcurrent from charging multiple devices, using high-power accessories like air compressors, or a short circuit in a connected device. If your phone charger suddenly stops working, check these first.
• Blower Motor (F07): The blower motor works hard, especially on high settings. A failing blower motor or resistance in the circuit can cause this fuse to blow. If your A/C or heat fan isn't working, this is a prime suspect.
• Radio / Infotainment (F30): While less common, issues with aftermarket stereo installations, faulty head units, or internal shorts can sometimes cause this fuse to blow, resulting in a blank screen or no audio.
• Trailer Brake Controller (F16) / Trailer Tow Lights (F52, F53, F54): If you frequently tow or have issues with your trailer's electrical system, these fuses can blow, especially if there's a short in the trailer wiring. Always check your trailer connections if you experience issues.

Always check the printed legend on your fuse box lid to verify the exact fuse configuration for your specific trim level, as there can be minor variations.
