How to Locate the Headlight Relay on a 2002 Impalaby Leonardo R. Grabkowski
The 2002 Chevy Impala's headlight receives its power from the headlight relay, like all other modern vehicles. If this relay is faulty, your headlights may not work even after you've replaced the bulbs. The first step to replacing the relay is locating it. There are several fuse boxes in your Impala that contain a host of relays and fuses. The box with the headlight relay is located inside the vehicle on the edge of the dash.
Turn the Impala's engine off. Open the driver-side door. Inspect the end of the dash on the driver's side, near the steering wheel. You'll see a panel labeled "Fuses." It has a small handle on it.
Grasp the handle and pull the panel off. Behind it you'll find several relays and fuses.
Look in the lower-left corner of the compartment. You'll see the headlight relay. It's labeled "Headlamp Relay."
