Solution

1. Preparation

Gather tools: socket set, multimeter, flat-head screwdriver, and wire connectors.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to avoid electrical shocks.

2. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the rear hatch and remove it using a fuse puller.
Inspect the fuse for continuity using a multimeter; if blown, replace it with a fuse of the same amperage (usually indicated on the fuse).

3. Inspect and Test the Rear Hatch Actuator

Remove the interior panel of the rear hatch using a flat-head screwdriver to pry off any clips.
Locate the actuator motor, which is typically mounted near the latch.
Using a multimeter, check for voltage at the actuator connector while someone presses the unlock button.
If voltage is present but the actuator does not move, replace the actuator motor.

4. Repair or Replace the Latch Mechanism

If the latch mechanism appears stuck or damaged, remove it carefully by unscrewing the bolts.
Inspect for any debris or rust; clean or replace any damaged components as needed.
Reinstall the latch and ensure it engages correctly with the striker when the hatch is closed.

5. Reassemble and Test

Reattach the interior panel of the rear hatch, ensuring all clips are secured.
Reconnect the negative battery terminal.
Test the rear hatch operation using the key fob and manual release lever.
