1. Open the rear cargo door/hatch.
2. Locate the taillight assembly. The left taillight is on the driver's side.
3. Remove the access panel: This is usually a plastic cover held in place by clips or screws. You may need a small flathead screwdriver or trim tool to gently pry it loose. Be careful not to break any clips. The location and type of fasteners will vary slightly depending on trim level. Look carefully around the edges of the taillight housing for clips or screws.
4. Access the bulb socket: Once the access panel is removed, you should be able to see the bulb socket. The brake light bulb is typically one of the larger bulbs in the assembly.
5. Disconnect the bulb: Gently twist the bulb socket (counterclockwise is usually the way to go) to disconnect it from the wiring harness.
6. Remove the bulb: Carefully pull the old bulb straight out of the socket.
7. Install the new bulb: Insert the new bulb into the socket, making sure it's correctly oriented. (Usually there's a small notch or key that aligns with the socket). Twist the bulb clockwise to secure it.
8. Reconnect the bulb socket: Carefully push the bulb socket back into place.
9. Replace the access panel: Secure the access panel back into place, making sure all clips are properly engaged.
10. Test the brake lights: Turn on your brake lights to make sure the new bulb is working.
Important Considerations:
* Bulb Type: Before you start, it's a good idea to identify the correct bulb type. Check your owner's manual or the old bulb itself (it usually has a code printed on it). Auto parts stores can help you find the right replacement.
* Gloves: Consider wearing gloves to avoid getting grease or dirt on the new bulb.
* Safety: Make sure the vehicle is turned off and the parking brake is engaged.
* If you are uncomfortable working on your vehicle: Take it to a qualified mechanic.
