2016 Chevrolet Tahoe Fuse Box Diagram

Quick answer

The 2016 Chevrolet Tahoe has three primary fuse box locations:

• Engine Compartment Fuse Block: Located on the driver's side of the engine bay, near the battery.
• Instrument Panel Fuse Block: Located on the driver's side of the dashboard, accessible when the driver's door is open.
• Rear Compartment Fuse Block: Located in the rear cargo area on the driver's side, behind an access panel.

Always verify fuse and relay locations with the diagrams printed inside your vehicle's fuse box covers, as configurations can vary based on trim level and optional equipment.

Engine Compartment Fuse Block

This fuse block contains higher-amperage fuses and relays that control core vehicle functions like the engine, transmission, cooling fans, and ABS.

Common Relays in this Location:

• Starter Relay: Engages the starter motor.
• Fuel Pump Relay: Powers the fuel pump.
• A/C Clutch Relay: Engages the air conditioning compressor.
• Cooling Fan Relays (High/Low): Controls the engine cooling fans.
• Run/Crank Relay: Provides power to ignition-related circuits during startup and operation.

Instrument Panel Fuse Block

Located on the driver's side of the dashboard, this panel handles most of the interior and cabin-related circuits, including lighting, infotainment, and power outlets.

Rear Compartment Fuse Block

Found in the cargo area, this fuse block often manages circuits related to the rear of the vehicle, such as the liftgate, rear defogger, and some chassis control modules.

How to Test a Fuse

Testing a fuse is a straightforward process.

1. Turn off the ignition and the affected component.
2. Locate and remove the suspect fuse. A fuse puller tool is often included in the fuse box lid, but small pliers can work in a pinch.
3. Visually inspect the fuse. Look at the metal strip inside the colored plastic housing. If the strip is broken or appears melted, the fuse is blown.
4. Use a multimeter (for a definitive test). Set your multimeter to the continuity setting (it often looks like a sound wave symbol). Touch one probe to each metal blade on the top of the fuse. If the multimeter beeps, the fuse is good. If it remains silent, the fuse is blown and has no continuity.

When replacing a fuse, always use a new fuse with the exact same amperage rating. Using a higher-rated fuse can cause severe damage to the electrical circuit and create a fire hazard.

Common Blown Fuses on This Vehicle

• Cigar Lighter / 12V Power Outlet Fuse (Instrument Panel, F10/F11): This is one of the most common fuses to blow. It's often caused by a faulty phone charger, a coin falling into the outlet, or plugging in a device that draws too much power. Before replacing the fuse, inspect the outlet for any foreign objects.
• Fuel Pump Fuse (Engine Compartment, F16): If your Tahoe cranks but won't start, this fuse is a good first check. A blown fuse could indicate a failing fuel pump that is drawing too much current. If a new fuse blows immediately, the fuel pump or its wiring likely has a short circuit.
• Trailer Brake/Lighting Fuses (Engine Compartment, F39 and others): Issues with trailer wiring are very common. A short in the trailer's wiring harness can frequently blow the trailer-related fuses in the truck. Always inspect the trailer plug and wiring before suspecting an issue with the vehicle itself.
