Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on the electrical components.

2. Inspect and Replace Fuses

Locate the fuse box under the dashboard and/or in the engine compartment.
Remove the trunk release fuse using a fuse puller.
Inspect the fuse for continuity; replace it if it is blown with a new fuse of the same amperage.

3. Check and Repair Wiring

Remove the trunk trim panel to access the trunk release actuator and wiring.
Visually inspect the wiring harness for any cuts, frays, or corrosion.
Repair any damaged wires using electrical tape or replace the wiring harness if necessary.

4. Test and Replace the Trunk Release Actuator

Use a multimeter to check the voltage at the actuator connector when the trunk release button is pressed.
If no voltage is present, the issue may lie in the switch or wiring.
If voltage is present but the actuator does not respond, remove the actuator from the trunk.
Replace the trunk release actuator with a new unit if it is found to be faulty.

5. Reassemble and Test

Reinstall the trunk trim panel securely.
Reconnect the battery.
Test the trunk release button inside the car and the key fob to ensure they operate properly.
