Solution

1. Preparation

Gather tools: socket set, flathead and Phillips screwdrivers, multimeter, and a replacement battery for the key fob if needed.
Ensure the vehicle is in park and the ignition is off.

2. Replace Key Fob Battery (if applicable)

Open the key fob using a flathead screwdriver.
Remove the old battery and replace it with a new CR2032 battery, ensuring correct polarity.
Reassemble the key fob and test the hatch operation.

3. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the rear hatch using the diagram on the fuse box cover.
Remove the fuse with a fuse puller and inspect it for damage. Replace with a new fuse of the same amperage if blown.

4. Access and Inspect the Hatch Latch and Actuator

Open the rear hatch manually (if possible) or from inside the vehicle.
Remove the interior trim panel to access the latch and actuator.
- Use a Phillips screwdriver to remove screws and a trim removal tool to detach clips.
Visually inspect the latch and actuator for corrosion, wear, or damage.
If faulty, disconnect the electrical connector and remove the actuator using a socket set.

5. Replace the Hatch Actuator (if necessary)

Install the new actuator by reversing the removal steps.
Reconnect the electrical connector and ensure the latch operates smoothly.
Reinstall the interior trim panel.

6. Final Check and Reassemble

Test the rear hatch operation using the key fob and inside release.
Reassemble any remaining components and ensure everything is secure.
