2025 Chevrolet Tahoe Fuse Box Diagram & Amperage

Quick Answer

The 2025 Chevrolet Tahoe features three main fuse box locations: under the hood, on the passenger side of the dashboard (kick panel), and in the rear cargo area.

Under-Hood Fuse Box

The under-hood fuse box is located in the engine bay, typically on the driver's side, near the battery. It contains fuses and relays for critical powertrain and under-hood electrical components. Always verify the exact layout with the diagram on your fuse box cover.

Passenger Side Dash Fuse Box

This fuse box is located on the passenger side of the dashboard, behind a removable panel or kick panel. It primarily houses fuses for interior electrical components and accessories.

Rear Cargo Area Fuse Box

Located in the rear cargo area, often on the driver's side behind a trim panel, this fuse box handles power for rear accessories, trailer connections, and other systems located in the back of the vehicle.

How to Test a Fuse

Testing a fuse is a straightforward process and can help you quickly diagnose an electrical issue. Here’s how:

1. Locate the Fuse Box: Identify the correct fuse box for the circuit you're troubleshooting.
2. Identify the Suspect Fuse: Refer to the fuse box diagram (usually on the lid or in your owner's manual) to find the fuse for the component that isn't working.
3. Visual Inspection: Many fuses have a clear plastic body, allowing you to see the metal wire inside. If this wire is broken or melted, the fuse is blown and needs replacement.
4. Use a Fuse Tester or Multimeter: For opaque fuses or to be more thorough, use a fuse tester (a small tool with a light that illuminates if the fuse is good) or a multimeter set to continuity mode. Touch the tester probes to the two small metal test points on top of the fuse. If the light illuminates or the multimeter shows continuity, the fuse is good. If not, it's blown.
5. Remove and Replace: Use the fuse puller (often found in the fuse box lid) to carefully remove the blown fuse. Always replace a blown fuse with a new one of the exact same amperage rating, color, and type. Using a fuse with a higher amperage can cause severe electrical damage or even a fire.

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more common than others due to the nature of their circuits or connected accessories. If you're experiencing an electrical issue, start by checking these fuses first:

• Cigar Lighter / 12V Power Outlets: These fuses frequently blow due to overcurrent from charging multiple devices or using high-power accessories. If your phone charger or other accessories aren't working, check the relevant 12V outlet fuse in the passenger side dash fuse box.
• Radio / Infotainment System: Issues with the radio, touchscreen, or other infotainment features can often be traced back to a blown fuse in the passenger side dash fuse box, especially after installing aftermarket accessories or power surges.
• Blower Motor: If your HVAC fan suddenly stops working on all speeds, the blower motor fuse (located in the under-hood fuse box) is a common culprit. This can also be caused by a faulty blower motor resistor.
• Headlights / Tail Lights: While less frequent, a blown fuse can cause one or both headlights or tail lights to stop working. Always check the bulbs first, but if they're good, consult the under-hood or dash fuse boxes for the headlight/tail light fuses.

When troubleshooting, always remember to check the simplest solutions first. If a fuse repeatedly blows, it indicates a deeper electrical problem that needs professional diagnosis. Do not simply replace a repeatedly blowing fuse with a higher-amperage fuse, as this can lead to severe damage.
