2022 Chevrolet Silverado 2500HD Fuse Box Diagram & Amperage

Quick Answer

The 2022 Chevrolet Silverado 2500HD has multiple fuse box locations: one under the hood, one inside the cabin on the passenger kick panel, and another in the cargo area/trunk.

Under-Hood Fuse Block

The under-hood fuse block is located in the engine compartment, typically on the driver's side, near the battery. It contains fuses and relays for critical engine functions, lights, and other high-current accessories. Always consult the fuse diagram on the fuse box cover for the exact layout for your specific trim.

Passenger Kick Panel Fuse Block

The interior fuse block is located on the passenger side of the cabin, behind the kick panel. This fuse box typically controls accessories, interior lighting, and various electronic modules.

Cargo Area/Trunk Fuse Block

The cargo area fuse block is typically located behind a panel on the side of the cargo area or under the rear seat. This fuse box often handles accessories related to the rear of the vehicle, such as trailer lights and rear power outlets.

How to Test a Fuse

Testing a fuse is a straightforward process. You will need a fuse puller (usually found in the under-hood fuse box) and a multimeter or a fuse tester.

1. Locate the fuse box: Refer to the Quick Answer section above to find the correct fuse box.
2. Identify the suspect fuse: Use the tables above and the fuse box cover diagram to pinpoint the fuse for the circuit you're troubleshooting.
3. Remove the fuse: Carefully pull the fuse straight out using the fuse puller.
4. Visually inspect the fuse: Look at the small wire inside the fuse. If it's broken or melted, the fuse is blown. For opaque fuses, you'll need a tester.
5. Test with a multimeter (if needed): Set your multimeter to the continuity setting (often indicated by a speaker icon). Touch the probes to the metal contacts on both ends of the fuse. If the multimeter beeps or shows a reading close to zero ohms, the fuse is good. If it shows no continuity (OL or infinity), the fuse is blown.
6. Replace the fuse: If the fuse is blown, replace it with a new fuse of the exact same amperage (A) rating. 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 common culprits due to high usage or common issues. If you're experiencing a problem, these are good places to start your investigation:

• Cigar Lighter/12V Outlets (Under-hood F3 or Cargo Area F5): These fuses often blow due to overcurrent from charging multiple devices or using high-power accessories. Check the devices you're plugging in before replacing.
• Trailer Brake Controller (Under-hood F12): Issues with trailer wiring or a short in the trailer itself can cause this fuse to blow. Inspect your trailer's wiring harness for damage.
• Blower Motor (Under-hood F10 or Passenger Kick Panel F7): If your HVAC fan isn't working, this fuse is a likely suspect. A failing blower motor or an obstruction in the fan can cause it to draw too much current.
• Headlights (Under-hood F5-F8): While less common than accessory fuses, a short in the headlight circuit or a faulty bulb can on occasion cause a headlight fuse to blow. Check your bulbs first.
• Radio/Infotainment System (Passenger Kick Panel F1): Problems with the radio, an aftermarket accessory, or a short in the wiring can trip this fuse. Disconnect any recently installed accessories to see if the issue persists.

Always verify the printed legend on your fuse box lid, as fuse locations and amperages can vary slightly between trim levels and specific vehicle configurations.
