Solution

1. Preparation

Gather necessary tools: socket set, multimeter, trim removal tools, lubricant, and a flashlight.
Ensure the vehicle is parked on a flat surface, and the ignition is turned off.

2. Access Trunk Release Mechanism

Open the rear seats if applicable, or remove any trunk liner covering the latch mechanism using trim removal tools.
Locate the trunk release actuator; it is usually near the latch mechanism.

3. Inspect and Clean Components

Visually inspect the actuator and latch for any visible damage or debris.
Clean the latch mechanism and surrounding area with a suitable cleaner to remove dirt or grime.
Apply a silicone-based lubricant to the latch mechanism to ensure smooth operation.

4. Electrical Inspection

Use a multimeter to check for voltage at the trunk release actuator when the button is pressed.
If no voltage is detected, trace the wiring back to the switch and check for continuity.
Repair any damaged wiring or connections as necessary.

5. Replace Faulty Components

If the actuator is found to be faulty, disconnect the wiring harness, and remove the actuator using a socket set.
Install the new actuator, ensuring it is securely fastened.
Reconnect the wiring harness and test the actuator operation.

6. Reassemble Components

Replace any trunk liner or covers removed during the process.
Ensure all clips and fasteners are secured properly.
