Understanding the fuse box in your 2005 Chevy Impala is essential for quick troubleshooting of electrical issues like dead lights or malfunctioning accessories. Fuses protect circuits from damage, and locating them involves knowing key spots and the diagram.
Fuse Box Locations
The primary fuse box is located in the engine compartment near the battery, typically covered by a plastic lid. The secondary fuse box is inside the passenger compartment, often behind the glove box or under the dashboard on the driver's side. Both are labeled clearly.
Reading the Fuse Box Diagram
Each fuse box has a diagram printed on its lid or provided in the owner's manual. It lists fuse numbers, amperage ratings, and their corresponding circuits (e.g., Fuse #10 for headlights). Refer to this diagram to avoid confusion.

Steps to Locate Fuses Easily
- Identify the affected component: Determine if the issue relates to an engine or cabin item to choose the right fuse box.
- Access the fuse box: For under-hood, remove the plastic cover by pressing tabs. For interior, open the glove box and gently pry off the panel for access.
- Refer to the diagram: Match the fuse number to your issue using the lid diagram.
- Use the fuse puller tool: Included in the fuse box, it allows safe removal for inspection or replacement.
Always disconnect the battery before handling fuses to prevent electrical shorts.
