2022 Chevrolet Suburban Fuse Box Diagram & Amperage

Quick answer

The 2022 Chevrolet Suburban has three main fuse box locations: one under the hood, one in the instrument panel (driver's side kick panel), and one in the rear cargo area.

Under-Hood Fuse Box

The under-hood fuse box is located in the engine compartment on the driver's side, near the battery. This box houses fuses and relays for critical engine functions, lights, and other high-current accessories.

Note: Fuse numbers and circuits may vary slightly based on your Suburban's trim level and optional equipment. Always refer to the fuse diagram printed on the inside of your fuse box lid for the most accurate information.

Instrument Panel Fuse Box (Driver's Side Kick Panel)

This fuse box is located on the driver's side of the dashboard, behind a removable panel near the kick panel. It protects circuits for various interior components and accessories.

Note: The exact fuse layout can differ based on your specific vehicle's configuration. Always consult the diagram on your fuse box cover.

Rear Cargo Area Fuse Box

Located in the rear cargo area, typically on the driver's side behind a trim panel, this fuse box controls power to various rear-specific accessories and features.

As with all fuse boxes, verify the specific fuse locations and ratings with the diagram provided in your vehicle's owner's manual or on the fuse box cover.

How to Test a Fuse

Testing a fuse is a straightforward process:

1. Locate the suspected fuse: Refer to the appropriate fuse box diagram to find the fuse for the component that isn't working.
2. Visually inspect: Many fuses have a visible wire inside. If this wire is broken or melted, the fuse is blown. You can often see charring or discoloration in the fuse as well.
3. Use a fuse tester or multimeter: For a more accurate test, use a fuse tester (a simple tool with a light that illuminates if the fuse is good) or a multimeter. With the ignition off, carefully remove the fuse. Touch the probes of the tester to the two exposed metal terminals on the top of the fuse. If the light illuminates or the multimeter shows continuity, the fuse is good. If not, it's blown.
4. Replace with the correct rating: Always replace a blown fuse with a new one of the exact same amperage rating and color. Using a fuse with a higher rating can lead to serious electrical damage or fire.

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more commonly affected due to heavy use or typical wear and tear. If you're experiencing an electrical issue, here are some commonly blown fuses on a 2022 Chevrolet Suburban and what to check first:

• Cigar Lighter/12V Power Outlets (F2 - Instrument Panel): These fuses often blow due to over-current from devices plugged in, especially chargers for multiple electronics or aftermarket accessories. If your phone isn't charging, check this first.
• Blower Motor (F11 - Under-Hood): The blower motor fuse can blow if the motor itself is struggling (e.g., due to debris in the fan) or if there's a short in the circuit. If your climate control fan isn't working, this is a prime suspect.
• Radio/Infotainment (F1 - Instrument Panel): Issues with the radio, touch screen, or other infotainment features often point to this fuse. A sudden power surge or even a software glitch can sometimes trigger a blown fuse in this circuit.
• Trailer Brake/Trailer Wiring (F4, F5 - Rear Cargo Area): If you frequently tow, the trailer wiring fuses can blow due to issues with the trailer's electrical system, such as a short in the trailer lights or brakes. Always inspect the trailer wiring if these fuses are blown.
• Headlights (F5, F6, F7, F8 - Under-Hood): While less common with modern LED systems, a short in the headlight circuit or a faulty bulb (if applicable) can still cause a fuse to blow, leading to a loss of headlight function.

When a fuse blows, it's often an indication of an underlying problem. While replacing the fuse might temporarily resolve the issue, it's wise to investigate why it blew in the first place to prevent future problems.
