1. Under the hood: This fuse box typically contains larger fuses and relays, often protecting higher-amperage circuits. It's usually located near the battery.
2. Inside the vehicle: This fuse panel is generally located inside the driver's side dashboard, often near the steering column or lower instrument panel. This box usually contains smaller fuses protecting interior accessories and electronics.
To be absolutely certain: Check your owner's manual. It will have a diagram showing the location of both fuse boxes and a legend explaining which fuse protects which circuit. This is the best way to avoid damaging anything.
