Quick answer
The 2025 GMC Acadia features three main fuse box locations: one under the hood, one inside the cabin on the passenger side kick panel, and another in the rear cargo area.
Under-hood Fuse Box
This fuse box is located in the engine compartment, typically on the driver's side, near the battery. It houses fuses and relays for critical engine functions, lights, and other high-power accessories.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F1 | 15A | Blue | ECM/PCM (Engine Control Module/Powertrain Control Module) |
| F2 | 20A | Yellow | Fuel Pump |
| F3 | 25A | Clear | Ignition Coils |
| F4 | 30A | Green | Starter Solenoid |
| F5 | 10A | Red | Headlight, Low Beam (Left) |
| F6 | 10A | Red | Headlight, Low Beam (Right) |
| F8 | 15A | Blue | Headlight, High Beam (Right) |
| F9 | 20A | Yellow | ABS Module |
| F10 | 30A | Green | Blower Motor |
| F11 | 10A | Red | A/C Clutch |
| F12 | 20A | Yellow | Trailer Brake Control (if equipped) |
Relays:
- RL1: Fuel Pump Relay
- RL2: Starter Relay
- RL3: Headlight High Beam Relay
- RL4: A/C Clutch Relay
Passenger Side Kick Panel Fuse Box
Located on the passenger side of the cabin, behind a removable panel near the floorboard. This fuse box typically protects interior electrical components.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F1 | 10A | Red | Radio/Infotainment System |
| F2 | 15A | Blue | 12V Power Outlet (Front) |
| F3 | 15A | Blue | Wiper Motor |
| F4 | 10A | Red | Airbag Module |
| F5 | 7.5A | Brown | Brake Lights |
| F6 | 10A | Red | Turn Signals |
| F7 | 5A | Tan | Instrument Cluster |
| F8 | 10A | Red | Power Windows (Front) |
| F9 | 10A | Red | Sunroof (if equipped) |
| F10 | 20A | Yellow | Blower Motor Control Module (Lower speeds) |
| F11 | 15A | Blue | Heated Seats (Front) |
Rear Cargo Area Fuse Box
This fuse box is typically located in the rear cargo area, often behind a trim panel on the driver's or passenger side. It protects accessories for the rear of the vehicle.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F1 | 15A | Blue | 12V Power Outlet (Rear) |
| F2 | 10A | Red | Taillights / Parking Lights |
| F3 | 20A | Yellow | Power Liftgate (if equipped) |
| F4 | 15A | Blue | Trailer Lighting (if equipped) |
| F5 | 10A | Red | Rear Wiper |
| F6 | 20A | Yellow | Rear Defrost |
How to test a fuse
Testing a fuse is a straightforward process. First, locate the fuse box relevant to the circuit you're troubleshooting. Most fuse boxes have a diagram on the inside of the cover indicating which fuse protects which component. You can visually inspect a fuse to see if the small wire inside is broken. If it is, the fuse is blown. For a more accurate test, use a fuse puller (usually found in the fuse box or tool kit) to remove the suspected fuse. Then, use a multimeter set to continuity mode, touching the probes to the two metal prongs on the fuse. A good fuse will show continuity, while a blown fuse will show an open circuit. Alternatively, a fuse tester tool can quickly indicate if a fuse is good or bad with a light.
Common blown fuses on this vehicle
While any fuse can blow under certain conditions, some are more commonly affected due to heavy usage or specific component issues. In the 2025 GMC Acadia, common candidates for blown fuses include those protecting the cigar lighter/12V outlets, especially if devices drawing too much power are frequently plugged in. The blower motor fuse can also blow if the motor is experiencing issues or operating under strain. If your radio or infotainment system suddenly stops working, check its dedicated fuse in the cabin fuse box. Headlight and taillight fuses can also be common culprits if bulbs short out or there's a wiring issue. Always start by checking the fuse that corresponds to the non-functioning component. If a fuse blows repeatedly, it indicates a deeper electrical issue that needs professional diagnosis, not just a fuse replacement. Do not replace a fuse with one of a higher amperage rating, as this can lead to severe electrical damage or fire.

Before you pull a fuse on the 2025 GMC Acadia
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
