Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box, typically located under the dashboard or in the engine compartment.
Use a fuse puller or needle-nose pliers to remove the liftgate fuse.
Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.
Reconnect the battery and test the liftgate operation again.

3. Check and Repair Wiring

Visually inspect the wiring harness connected to the liftgate for any signs of wear, fraying, or corrosion.
If damage is found, carefully splice in new wiring using automotive-grade connectors and heat shrink tubing.
Ensure that all connections are secure and protected against moisture.

4. Test and Replace Liftgate Motor

If the motor is suspected to be faulty, remove the interior panel of the liftgate for access.
Disconnect the motor connector and test it with a multimeter for proper voltage.
If the motor does not receive power or fails to operate, replace it with a new motor.
Reassemble the panel and reconnect the battery.
