Tools you'll likely need:
* A Phillips head screwdriver (possibly a small one)
* A new backup light bulb (check your owner's manual for the correct bulb type and wattage)
Procedure (General Steps - Variations are possible):
1. Access the Taillight Assembly: You'll typically need to access the taillight from the inside of the trunk. Look for access panels or screws securing the interior trim panel that covers the taillight. Remove the necessary screws or panels to gain access.
2. Disconnect the Taillight Assembly: Once you have access, you should find a connector plugged into the back of the taillight assembly. Carefully disconnect this connector. Sometimes there's a small retaining clip; gently release it.
3. Remove the Taillight Assembly (If Necessary): In some cases, the whole taillight assembly might need to be removed to replace the bulb. This usually involves removing more screws or clips holding the assembly in place. Be gentle to avoid breaking any clips.
4. Access the Bulb: Once the taillight assembly is accessible (partially or fully removed), you should see the bulb sockets. The backup light bulb is usually one of the several bulbs in the assembly. It's often located towards the bottom or side of the assembly.
5. Remove the Old Bulb: Carefully twist the old bulb (usually a quarter-turn) to remove it from its socket. If the bulb is stuck, gently wiggle it before twisting. Avoid touching the glass part of the bulb with your bare fingers as the oils from your skin can shorten its lifespan.
6. Install the New Bulb: Carefully insert the new bulb into the socket and twist it to secure it. Make sure it's firmly seated.
7. Reassemble Everything: Reconnect the taillight connector. If you removed the taillight assembly, carefully put it back in place and secure it with the screws or clips. Reinstall any interior trim panels you removed.
8. Test the Bulb: Turn on your car's ignition and put it in reverse. Check if the backup light is working correctly.
Important Notes:
* Safety First: Always disconnect the battery's negative terminal before working on any car electrical system. This reduces the risk of short circuits.
* Bulb Type: Ensure you get the correct replacement bulb type. Incorrect bulbs can cause damage or malfunction. Your owner's manual will specify the correct type.
* If Unsure: If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic or auto repair shop. They have the tools and expertise to handle the job safely and efficiently.
This is a general guide, and the specifics might differ for your particular 2002 Chevy Impala. Referring to your owner's manual is crucial for a safe and accurate repair.
