1. Preparation:
* Gather tools: You'll need a screwdriver set (likely Phillips and possibly flathead), possibly a socket set (depending on the type of fasteners), pliers, and possibly a panel removal tool to avoid scratching the interior. A new trunk lock assembly is crucial, of course. Consider purchasing a repair manual specific to your 1995 Chevy Cavalier for detailed diagrams and torque specifications.
* Disconnect the battery's negative terminal: This is a safety precaution to prevent accidental shorts.
2. Accessing the Trunk Lock Mechanism:
This is the most challenging part, varying by Cavalier model. Here are possible scenarios:
* Interior Access: Some Cavaliers may allow access to the trunk lock mechanism from inside the trunk itself. You might need to remove interior trim panels to expose the lock mechanism. Look for screws or clips holding these panels in place. Carefully pry them off using a panel removal tool. Consult a repair manual to identify these access points.
* Exterior Access (Less Likely): In some cases, you might be able to access the mechanism from the exterior of the trunk, but this is less common and would usually involve removing the taillight assembly.
3. Removing the Old Trunk Lock:
* Disconnect the linkage: The trunk lock is connected to the trunk release handle by a linkage. Carefully disconnect this linkage.
* Remove fasteners: Once you have access to the lock mechanism, identify and remove the screws or bolts securing it to the trunk lid.
* Unplug the electrical connector (if applicable): Some Cavaliers might have an electrical connector for the trunk light or other features linked to the lock. Carefully unplug this connector.
4. Installing the New Trunk Lock:
* Connect the linkage: Attach the linkage from the new trunk lock to the trunk release handle.
* Secure the new lock: Carefully align the new lock mechanism with its mounting points and install the screws or bolts you removed previously. Tighten them securely, but avoid over-tightening.
* Reconnect the electrical connector (if applicable): Plug the electrical connector back in.
* Reinstall interior trim panels: Carefully replace any interior trim panels you removed to access the lock.
5. Testing:
* Reconnect the battery's negative terminal.
* Test the new trunk lock: Use the key to lock and unlock the trunk, and verify that the trunk release handle also functions correctly.
Important Considerations:
* Repair Manual: A repair manual specific to your 1995 Chevy Cavalier is strongly recommended. It will provide detailed instructions, diagrams, and torque specifications, greatly simplifying the process and preventing damage.
* Professional Assistance: If you are uncomfortable performing this repair yourself, consider taking your vehicle to a qualified mechanic. Incorrectly installing the lock could lead to further problems.
* Trunk Lid Removal: In some extreme cases, you might even need to remove the entire trunk lid to access and replace the lock, so it's best to have some prior experience if this is the case.
This is a general outline; the specific steps might differ based on your Cavalier's model. Always consult a repair manual for your specific vehicle before attempting this repair. Take your time, work carefully, and prioritize safety.
