Solution

1. Preparation

Tools Required: Socket set, multimeter, screwdriver set, trim removal tool
Ensure the vehicle is in "Park" mode and the ignition is off.
Disconnect the vehicle's 12V battery to prevent electrical shock.

2. Inspect and Repair Wiring

Remove the interior trim panel of the rear hatch using a trim removal tool.
Inspect the wiring harness for any frayed wires or loose connections.
If damaged, repair the wiring using electrical tape or replace the damaged section.
Reconnect any loose connectors securely.

3. Test and Replace the Hatch Actuator

Locate the rear hatch actuator, which is typically mounted near the latch mechanism.
Disconnect the actuator's electrical connector.
Use a multimeter to check for voltage at the connector while pressing the hatch release.
If no voltage is present, further investigate the wiring or switch.
If voltage is present but the actuator does not respond, remove the actuator using a socket set.
Replace the actuator with a new one by reversing the removal steps and reconnecting the electrical connector.

4. Reassemble Components

Reattach the interior trim panel, ensuring all clips and fasteners are secure.
Reconnect the 12V battery.
Test the rear hatch operation by pressing the release button.
