Tools You'll Need:
* New tail light assembly (ensure it's the correct one for your vehicle's year and side)
* Phillips head screwdriver (possibly a Torx screwdriver, depending on the screws)
* Possibly a small flathead screwdriver or trim tool (to help pry off plastic clips)
* Gloves (optional, but recommended to keep your hands clean)
Procedure:
1. Prepare the Vehicle: Park your Lacrosse on a level surface, engage the parking brake, and turn off the engine. It's a good idea to disconnect the negative terminal of your battery to prevent accidental shorts.
2. Access the Tail Light: You'll need to access the tail light from inside the trunk. Locate the access panel to the trunk area where the tail light is located. This usually involves removing some trim pieces or panels. There might be plastic clips holding these in place; gently pry them loose using a trim tool or flathead screwdriver to avoid breaking them. Be careful not to scratch the paint.
3. Disconnect the Electrical Connector: Once you have access to the tail light assembly, you'll need to disconnect the electrical connector. This is usually a simple push-and-release type of connector. Gently push on the release tab (often located on the side of the connector) and pull the connector away from the tail light. Take a picture or make a note of how the connector is plugged in, just in case you have trouble remembering when reassembling.
4. Remove the Tail Light Assembly: There are usually several screws holding the tail light assembly in place. Unscrew them using the appropriate screwdriver. Once the screws are removed, the tail light assembly should come out fairly easily. If it feels stuck, gently wiggle it free. There may be plastic clips providing additional retention; carefully work them loose if present.
5. Install the New Tail Light Assembly: Carefully align the new tail light assembly and reverse the removal process. First, connect the electrical connector securely. Then, carefully screw the tail light assembly into place. Ensure all screws are tightened.
6. Reassemble the Trunk Panel: Put all the removed trim panels or clips back into place.
7. Reconnecting the Battery: Connect the negative battery terminal.
8. Test the New Tail Light: Turn on your tail lights and brake lights to ensure everything is working correctly.
Important Considerations:
* Type of Screws: The screws holding the tail light in place might be Phillips or Torx. Check carefully before you start.
* Plastic Clips: Be very gentle when removing and reinstalling plastic clips. They can easily break.
* Wiring: If you encounter any damaged wiring, you'll need to address that before installing the new tail light. Consider consulting a professional mechanic if you are uncomfortable with any electrical work.
* Bulb Replacement: While you have the tail light assembly out, it's a good time to replace any burned-out bulbs.
If you're uncomfortable performing this repair yourself, it's always best to take your vehicle to a qualified mechanic. They have the experience and tools to do the job safely and correctly.
