Tools You'll Likely Need:
* Socket set: Various sizes, likely including metric sizes.
* Screwdrivers: Phillips and flathead, possibly both.
* Pliers: For wire connectors or stubborn fasteners.
* Wrench: Possibly adjustable.
* New trunk latch assembly: Make sure you get the correct part for your Sunfire's year and model.
* Electrical tape or connectors: If you need to disconnect and reconnect electrical wiring.
* Penetrating oil (PB Blaster or similar): To help loosen rusted or stuck bolts.
General Steps (Consult your repair manual for specifics):
1. Access the Latch: You'll likely need to access the latch mechanism from inside the trunk. This often involves removing the interior trunk paneling. This usually involves removing screws or clips holding the panel in place. Be gentle to avoid breaking any plastic clips.
2. Disconnect Electrical Connections: The trunk latch usually has a wiring harness connected to it. Carefully disconnect the electrical connector(s) from the latch. Take pictures or make notes to remember how everything connects during reassembly.
3. Remove the Old Latch: This is where the exact procedure varies the most depending on your year and model. The latch might be secured by:
* Bolts: These will need to be unscrewed. Penetrating oil can help if they're stuck.
* Clips: Carefully pry these off using the appropriate tool.
* Nuts and bolts from the inside of the trunk: This is common for access through the trunk liner.
* A combination of the above: Be patient and methodical.
4. Install the New Latch: Once the old latch is removed, carefully align and install the new latch mechanism in the reverse order of removal. Ensure the latch is properly seated and aligned before tightening any fasteners.
5. Reconnect Electrical Connections: Reconnect the electrical connector(s) to the new latch, making sure they're securely connected.
6. Reinstall Interior Panels: Reinstall the trunk paneling, making sure all screws and clips are properly secured.
7. Test the Latch: Test the new trunk latch to ensure it operates correctly both from the inside and outside of the vehicle.
Important Considerations:
* Safety First: Disconnect the negative battery terminal before starting any work to prevent accidental short circuits.
* Repair Manual: A repair manual is essential. It will provide specific diagrams and instructions for your vehicle's year and model.
* Patience: This job can be time-consuming and frustrating. Take your time and be methodical.
* Professional Help: If you are not comfortable performing this repair yourself, consider taking your vehicle to a qualified mechanic. The cost of a professional repair might be less than the cost of a damaged part or an injury.
This is a general guide. Always consult your vehicle's repair manual for specific instructions. Incorrect installation can lead to malfunctioning and potential safety hazards.
