2016 GMC Yukon: Fuse Box Diagram & Amperage

Quick Answer

Your 2016 GMC Yukon has three main fuse box locations:

• Under the Hood: A large fuse and relay center located on the driver's side of the engine compartment.
• Instrument Panel (Driver's Side): Accessible after opening the driver's door, on the outer side of the dashboard.
• Cargo Area (Rear): Located in the right-side trim panel in the rear cargo area.

Left Instrument Panel Fuse Box (Dash)

This fuse box is located on the driver’s side of the dashboard, accessible when the driver's door is open. It primarily handles interior circuits.

Under-Hood Fuse & Relay Box

This is the main fuse center, located on the driver's side of the engine bay. It contains high-amperage fuses and relays for critical vehicle systems. Always disconnect the battery before servicing high-amperage fuses or relays.

Note: Your Yukon's specific layout may vary slightly based on trim level (SLE, SLT, Denali) and options. Always confirm fuse locations with the diagram printed on the inside of the fuse box lid.

Under-Hood Relays:

• KR2: Run/Crank Relay
• KR3: Starter Relay
• KR7: Fuel Pump Relay
• KR10: A/C Compressor Clutch Relay
• KR12: Low Beam Headlamp Relay
• KR13: High Beam Headlamp Relay

Rear Cargo Area Fuse Box

This fuse box is found behind a small access panel on the right (passenger) side of the rear cargo area. It manages circuits for rear-of-vehicle components.

How to Test a Fuse

Visually inspecting a fuse is the quickest way to check it.

1. Safety First: Turn the vehicle's ignition completely off.
2. Locate & Remove: Find the suspect fuse using the diagrams above. Use a fuse puller (often included in the fuse box lid) or a pair of needle-nose pliers to gently pull the fuse straight out of its slot.
3. Inspect: Hold the fuse up to a light source. Inside the plastic body, you will see a small metal strip. If this strip is broken or looks burnt, the fuse is blown and needs to be replaced.
4. Replace: Always replace a blown fuse with a new one of the exact same amperage rating. Using a higher-amperage fuse can cause a fire. The amp rating is printed on top of the fuse.

For a more definitive test, you can use a multimeter set to continuity or resistance (Ohms). A good fuse will show continuity (or near-zero resistance). A blown fuse will show an open circuit (infinite resistance).

Common Blown Fuses on the 2016 GMC Yukon

• Power Outlet / Cigar Lighter Fuse (Dash F11, Rear F3): 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 (Under-hood F15): If your Yukon cranks but won't start, the fuel pump fuse is a prime suspect. If this fuse is blown, it could indicate a failing fuel pump that is drawing too much current. If the replacement fuse blows immediately, have the fuel pump circuit diagnosed by a professional.

• Trailer Light Fuses (Under-hood F23, F30, F70): Issues with trailer wiring are very common. A short circuit in the trailer's wiring harness or a faulty light on the trailer itself will often blow one of the tow-related fuses on the truck. If a fuse blows as soon as you connect your trailer, the problem is almost certainly on the trailer side.

Fuse box issues can be frustrating to diagnose. If you've checked the basics and are still having trouble, it might be time to call in a professional.
