Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, screwdrivers, and possibly a replacement fuse or motor.
Disconnect the vehicle's 12V battery to ensure safety during repairs.

2. Inspect and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the trunk.
Remove the cover and use a fuse puller to extract the liftgate fuse.
Inspect the fuse for continuity using a multimeter. If it is blown, replace it with a fuse of the same amperage rating.
Reconnect the fuse box cover and the vehicle's battery.

3. Check Wiring and Connectors

Remove the interior trim panel of the liftgate to access the wiring harness.
Visually inspect the wiring for any signs of damage, such as fraying or corrosion.
Use a multimeter to check for continuity in the wires. Repair or replace any damaged wiring or connectors as necessary.

4. Test and Replace Liftgate Motor

If the motor does not respond during the direct power test, it may need replacement.
Disconnect the power liftgate motor by removing the electrical connector and securing the bolts holding the motor.
Install the new liftgate motor by reversing these steps, ensuring that all connectors are securely attached.
Reattach the interior trim panel.

5. Finalize and Test

Reconnect the vehicle’s battery.
Test the liftgate operation with the key fob and interior button to ensure proper functionality.
