Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working.

2. Inspect and Replace Fuses

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box, typically found under the dashboard or in the trunk.
Identify the fuse(s) associated with the liftgate (refer to the owner’s manual).
Remove the fuse using the fuse puller and inspect it for continuity.
Replace any blown fuses with the same amperage rating.

3. Check Liftgate Switch

Tools Required: Multimeter.
Remove the interior panel around the liftgate switch.
Disconnect the switch connector and use a multimeter to check for continuity when the switch is pressed.
If faulty, replace the switch with a new one.

4. Inspect Wiring Harness

Visually inspect the wiring harness leading to the liftgate for any signs of wear, fraying, or corrosion.
Repair or replace any damaged sections of the wiring harness as necessary.

5. Test Liftgate Motor

Tools Required: Jumper wires.
Disconnect the liftgate motor connector.
Using jumper wires, connect the motor directly to the battery to test its operation.
If the motor does not operate, it may need to be replaced.

6. Reassemble and Test

Reconnect all components and the battery terminal.
Test the power liftgate operation using the key fob and manual switch.
