Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean Liftgate Mechanism

Remove any debris or obstructions around the liftgate hinges and latch.
Lubricate the hinges and latch with a silicone-based lubricant to ensure smooth operation.

3. Check Electrical Connections

Reconnect the battery and use the OBD-II scanner to clear any fault codes.
Inspect and clean all electrical connectors leading to the liftgate motor, ensuring they are secure and free of corrosion.

4. Test Liftgate Motor

If the liftgate still does not close, locate the liftgate motor assembly.
Remove the liftgate trim panel to access the motor (using a trim removal tool).
Disconnect the motor's electrical connector and apply direct power (12V) to the motor terminals to test for operation.
If the motor does not operate, replace it with a new unit.

5. Reassemble

Reinstall the liftgate trim panel securely.
Reconnect the negative battery terminal.
Ensure all tools are removed from the area.
