2015 Chevrolet Tahoe Fuse Box Diagram & Amperage

Quick answer

The 2015 Chevrolet Tahoe features three main fuse box locations: under the hood (engine compartment), inside the cabin (instrument panel/dash), and in the rear cargo area.

Under-Hood Fuse Box

This fuse box is located in the engine compartment 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 diagram on the fuse box lid for the most accurate information, as configurations can vary slightly by trim level.

Instrument Panel Fuse Box (Dash)

Located on the passenger side of the dashboard, behind a removable panel, this fuse box handles various interior electrical components. You may need to open the passenger door and gently pry off the panel to access it.

Rear Cargo Area Fuse Box

This fuse box is typically located on the driver's side of the cargo area, behind a trim panel. It provides power to rear accessories, trailer connections, and other optional equipment.

How to test a fuse

Testing a fuse is a straightforward process that can save you time and money. Here's how:

1. Safety First: Turn off the ignition and disconnect the negative battery terminal, especially when working on under-hood fuses. This prevents accidental short circuits.
2. Locate the Fuse: Refer to your vehicle's owner's manual or the fuse box lid diagram to find the fuse you suspect is blown.
3. Visual Inspection: Pull the fuse straight out using a fuse puller (usually found in the fuse box) or small needle-nose pliers. Hold it up to the light. If the metal wire or filament inside is broken or melted, the fuse is blown.
4. Using a Multimeter (Recommended):
   • Set your multimeter to the continuity or ohms setting.
   • Touch the probes to the metal terminals on top of the fuse. Do not touch the probes to the fuse body.
   • A healthy fuse will show a reading of continuity (a low resistance or a beep, depending on your multimeter). A blown fuse will show no continuity or an open circuit.
5. Replace with Correct Fuse: If the fuse is blown, replace it with a new fuse of the exact same amperage rating and physical size. 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 eventually fail, some circuits on the 2015 Chevrolet Tahoe are more prone to issues due to their frequent use or connection to problematic components. If you're experiencing an electrical issue, start by checking these fuses:

• Cigar Lighter / 12V Outlets (Under-Dash F3 & F4, Rear Cargo F10): These are frequently blown due to charging faulty devices or plugging in high-power accessories that exceed the circuit's rating. If your phone charger or air compressor isn't working, check these first.
• Blower Motor (Under-Hood F13, F14 (A/C Clutch)): If your climate control fan isn't working on any speed, or the A/C isn't blowing cold, a blown fuse here is a common culprit. A failing blower motor can draw too much current and cause the fuse to blow.
• Trailer Brake Controller (Under-Hood F12): Owners who frequently tow or have issues with their trailer wiring may find this fuse blown. Always ensure your trailer wiring is in good condition to prevent shorts.
• Headlights (Under-Hood F5-F8): While less common with modern vehicles, a short in a headlight bulb or wiring can still blow these fuses. If one or both of your headlights are out, but the bulbs appear good, check these fuses.
• Radio/Infotainment (Under-Dash F1): If your stereo suddenly goes dead, this fuse is a prime suspect. It could be due to a short within the radio unit itself or a problem with an accessory connected to it.

Always verify the printed legend in the fuse box lid for the most accurate and up-to-date information for your specific trim and model year, as variations can occur.
