Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, and a trim removal tool.
Disconnect the vehicle battery to ensure safety during electrical work.

2. Access the Trunk Latch

Open the rear hatch as much as possible.
Remove any trim panels covering the trunk latch to access it. Use a trim removal tool to gently pry off panels without damaging clips.

3. Inspect and Test the Trunk Latch Mechanism

Visually inspect the latch for damage or foreign objects that may be obstructing it.
Using a multimeter, check the voltage at the latch actuator connector while pressing the trunk release button. If no voltage is present, trace the wiring.

4. Repair or Replace the Trunk Latch

If the latch is damaged, remove it by unbolting it from the trunk frame. Use a socket set for this.
Install the new latch by reversing the removal steps. Ensure it is securely bolted in place.
If the wiring was damaged, repair any broken connections or replace the wiring harness as necessary.

5. Reassemble and Test

Reattach the trim panels over the latch area.
Reconnect the vehicle battery.
Test the trunk release button and key fob to ensure the trunk opens properly.
