Solution

1. Preparation

Gather tools including a socket set, multimeter, and OBD-II scanner.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Fuse Inspection and Replacement

Locate the fuse box: Refer to the owner’s manual to find the location of the fuse box.
Remove the fuse: Use a fuse puller or pliers to remove the liftgate fuse.
Inspect the fuse: Check for any visible signs of damage or a broken filament.
Replace the fuse: If faulty, replace it with a new fuse of the same amperage.

3. Key Fob Battery Replacement

Open the key fob: Use a small flat-head screwdriver to gently pry open the key fob.
Replace the battery: Remove the old battery and insert a new one, ensuring proper polarity.
Reassemble the fob: Snap the key fob back together securely.

4. Liftgate Motor Test

Remove the interior trim panel: Use a trim removal tool to carefully detach the panel around the liftgate.
Locate the liftgate motor: Identify the motor connected to the liftgate mechanism.
Test the motor: Connect a multimeter to the motor terminals and activate the liftgate switch to check for voltage.
Replace the motor if necessary: If no voltage is detected or the motor is not functioning, replace it with a new one.

5. Wiring Inspection

Inspect wiring harness: Check for wear, fraying, or corrosion in the wiring leading to the liftgate motor.
Repair any damage: Use electrical tape to insulate damaged areas or replace damaged wires as needed.

6. Reassembly and Final Checks

Reattach the interior trim panel: Ensure all clips and fasteners are secure.
Reconnect the battery terminal: Reconnect the negative battery terminal.
