Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the vehicle's battery to prevent electrical shock.

2. Inspect and Repair Wiring

Remove the interior trim panel around the rear hatch area using a trim removal tool.
Check the wiring harness for any frayed or damaged wires; repair or replace as needed.
Inspect connectors for corrosion; clean or replace them if necessary.

3. Test and Replace the Hatch Release Mechanism

Locate the hatch release actuator; it is typically mounted near the latch assembly.
Use a multimeter to test the actuator for continuity; replace if it fails to show continuity.
If the actuator is functional, check the latch mechanism for obstructions or misalignment.
Lubricate the latch with appropriate automotive lubricant to ensure smooth operation.

4. Reassemble and Test

Reinstall the trim panel securely.
Reconnect the vehicle's battery and power on the vehicle.
Test the rear hatch operation using both the release button and the manual lever.
