Quick Answer
The 2020 GMC Acadia has multiple fuse box locations to protect its electrical systems. You'll find fuse boxes in the following locations:
- Under-hood Fuse Box: Located in the engine compartment, typically near the battery on the driver's side.
- Instrument Panel Fuse Box (Driver Side): Located inside the cabin, often behind a panel on the driver's side of the dashboard.
- Rear Cargo Area Fuse Box (Passenger Side): Located in the rear cargo area, usually behind a trim panel on the passenger side.
Under-hood Fuse Box
The under-hood fuse box contains fuses and relays for critical engine functions, cooling systems, and some exterior lighting. Always refer to the fuse diagram on the underside of the fuse box cover for the most accurate information for your specific vehicle.
Here's a general overview of common fuses and relays you might find:
| Fuse # | Amperage | Color | Circuit / Component Protected |
|---|---|---|---|
| F1 | 15A | Blue | ECM/PCM (Engine Control Module/Powertrain Control Module) |
| F2 | 20A | Yellow | Fuel Pump |
| F3 | 10A | Red | Ignition Coil/Ignition System |
| F4 | 30A | Green | Starter Relay |
| F5 | 10A | Red | Headlight, Low Beam (Left) |
| F6 | 10A | Red | Headlight, Low Beam (Right) |
| F7 | 15A | Blue | Headlight, High Beam (Left) |
| F8 | 15A | Blue | Headlight, High Beam (Right) |
| F9 | 25A | Natural | Blower Motor (Heater/AC) |
| F10 | 10A | Red | A/C Clutch |
| F11 | 40A | Green | ABS Module (Anti-lock Braking System) |
| F12 | 15A | Blue | Horn |
| F13 | 20A | Yellow | Cooling Fan 1 |
| F14 | 20A | Yellow | Cooling Fan 2 |
| F15 | 15A | Blue | Washer Pump |
Relay Locations (Under-hood):
The under-hood fuse box also houses several relays for high-current circuits. Common relays include:
- RL1: Starter Relay
- RL2: Fuel Pump Relay
- RL3: Cooling Fan Relay 1
- RL4: Cooling Fan Relay 2
- RL5: A/C Compressor Clutch Relay
- RL6: Headlight High Beam Relay
Instrument Panel Fuse Box (Driver Side)
This fuse box manages electrical components crucial to the cabin, comfort, and interior accessories. It
Before you pull a fuse on the 2020 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.
