If the latch is damaged or not functioning, remove the bolts securing the latch mechanism using a socket set.
Disconnect the wiring harness from the latch motor.
Install the new latch by reversing the removal steps, ensuring proper alignment and securing all bolts to the manufacturer’s torque specifications.
Reconnect the wiring harness.

5. Reinstall the Trim Panel

Reattach the trunk trim panel and secure it with screws and clips.
Reconnect any wiring harnesses that were removed.
Ensure all fasteners are tightened properly.
