1. Remove the lower trim panel: There's usually a panel covering the fuse box area. It's usually held in place by clips. Carefully pry it loose using a flat-head screwdriver or trim removal tool. Be gentle to avoid breaking the plastic. Start at the edges and work your way around. Some Impalas might require removing the glove box completely or partially to access this panel.
2. Locate the fuse box: Once the trim panel is removed, the fuse box will be visible. It's usually a rectangular box with a cover.
3. Open the fuse box cover: The cover may simply lift off or may have a latch or clip. Carefully examine the cover to see how it opens.
Important Note: Consult your owner's manual. The precise location and method of opening the fuse box may vary slightly depending on the specific trim level of your 2003 Impala. The manual will have diagrams and instructions specific to your vehicle.
