Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, and a torque wrench.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect Fuses

Locate the fuse box under the dashboard or in the engine compartment.
Remove the liftgate fuse using a fuse puller or flathead screwdriver.
Inspect the fuse for continuity. Replace with the same amperage if blown.

3. Test the Liftgate Switch

Disconnect the battery to ensure safety.
Remove the power liftgate switch from the panel.
Using a multimeter, set to the continuity setting, probe the terminals of the switch.
Replace the switch if there is no continuity when the button is pressed.

4. Check the Wiring Harness

Visually inspect the wiring harness connected to the liftgate for any frays, corrosion, or loose connections.
Repair or replace any damaged wires.
Reconnect any loose connectors and ensure a tight fit.

5. Inspect Liftgate Components

If the liftgate is not closing fully, inspect the liftgate latch and make sure it is not obstructed or damaged.
Check the liftgate struts for wear and ensure they are functioning properly. Replace if necessary.

6. Reassemble and Test

Reconnect the battery.
Test the liftgate operation with the key fob and interior switch.
Ensure the liftgate opens and closes smoothly without obstruction.
