Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to avoid electrical shock.
Tools required: Socket set, multimeter, OBD-II scanner, screwdrivers.

2. Check and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse associated with the power liftgate (refer to the owner’s manual).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if it is blown with a fuse of the same amperage.

3. Inspect and Repair Wiring

Visually inspect the wiring harness connected to the liftgate switch and motor for fraying, corrosion, or disconnection.
Repair any damaged wires with electrical tape or replace them as necessary.
Ensure all connections are secure.

4. Test and Replace Liftgate Motor

Use a multimeter to test the liftgate motor for continuity.
If there is no continuity, replace the liftgate motor.
To replace, remove any covers or panels blocking access to the motor.
Disconnect the motor’s electrical connector and remove the mounting bolts.
Install the new motor by reversing the removal process.

5. Reassemble and Reconnect

Reattach any panels or covers removed during the repair.
Reconnect the vehicle's battery.
Test the power liftgate operation using the key fob and interior switch.
