Solution

1. Preparation

Gather necessary tools: socket set, multimeter, and a flat-head screwdriver.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace Fuse

Locate the fuse box: Refer to the owner's manual for the exact location.
Inspect the fuse: Remove the fuse for the tailgate using a fuse puller.
Replace if blown: If the fuse is faulty, replace it with a new one of the same amperage (usually 10A).
Reconnect the battery: After replacement, reconnect the battery and test the hatch operation.

3. Inspect Electrical Connections

Access the hatch motor: Remove the interior panel of the rear hatch using a flat-head screwdriver to gently pry it off.
Check connections: Inspect the wiring harness connected to the hatch motor for any loose or damaged wires.
Test the motor: Using a multimeter, check for voltage at the hatch motor connector when the hatch is attempted to be opened. If voltage is present but the motor does not operate, replace the motor.

4. Clean and Lubricate Mechanisms

Clean latch assembly: Use a cleaning solvent to remove any dirt or debris from the latch mechanism.
Lubricate moving parts: Apply a silicone-based lubricant to the latch and hinges to ensure smooth operation.

5. Reassemble and Test

Reattach interior panel: Securely fasten the interior panel back in place once repairs are completed.
Reconnect battery: Ensure the battery is reconnected securely.
Test functionality: Use the key fob and manual release to test the hatch operation.
