Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, flathead screwdriver, and a replacement fuse (if necessary).
Ensure the vehicle is parked on a flat surface and the engine is turned off.

2. Replacing the Fuse

Locate the Fuse Box: Open the driver’s side door and find the fuse box cover beneath the dashboard.
Remove the Fuse Box Cover: Use a flathead screwdriver to gently pry off the cover.
Identify the Liftgate Fuse: Refer to the fuse diagram on the cover or in the owner's manual to find the correct fuse.
Replace the Fuse: If the fuse is blown, remove it using fuse pullers and insert a new fuse of the same amperage.
Reattach the Fuse Box Cover.

3. Testing and Replacing the Liftgate Actuator

Access the Liftgate Panel: Open the liftgate (if possible) and remove the inner trim panel using a socket set and screwdriver.
Locate the Actuator: Identify the liftgate actuator, which is typically located near the latch mechanism.
Test the Actuator: Use a multimeter to check if the actuator is receiving power when the liftgate button is pressed.
Replace the Actuator: If defective, disconnect the wiring harness, remove the actuator, and install a new one. Reconnect the wiring harness.

4. Reassemble the Liftgate Panel

Replace the inner trim panel, ensuring all clips are secured.
Test the liftgate operation before closing the trim.
