Solution

1. Preparation

Gather all necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery to prevent any electrical shorts during repairs.

2. Check and Replace Fuses

Locate the fuse box (refer to the owner’s manual for exact location).
Identify the fuse related to the tailgate release (usually labeled).
Remove the fuse using a fuse puller and inspect it for damage.
If blown, replace with a new fuse of the same amperage (usually 10A or 15A).
Reconnect the battery terminal.

3. Inspect and Repair Wiring

Visually inspect the wiring harness and connectors for any signs of wear, fraying, or corrosion.
If any damaged wiring is found, splice in new wire of the same gauge and re-insulate the connection.
Ensure all connectors are securely fastened and free of dirt or corrosion.

4. Test the Tailgate Release Mechanism

Reconnect the negative battery terminal.
Test the tailgate release button from the key fob and the interior switch.
If the tailgate still does not open, proceed to remove the tailgate trim panel.

5. Remove Tailgate Trim Panel

Using a trim removal tool, carefully pry off the tailgate trim panel.
Remove any screws or clips securing the panel and set it aside.
Access the tailgate latch assembly and check for mechanical issues or obstructions.

6. Repair or Replace Tailgate Latch

If the latch appears damaged, remove it by unscrewing the securing bolts.
Install the new latch in reverse order and ensure it is properly aligned and secured.
Reinstall the tailgate trim panel and ensure all clips and screws are properly secured.
