Carefully remove any trim pieces surrounding the door panel using a flathead screwdriver to avoid damage.
Use a Torx screwdriver to remove screws securing the door panel.
Gently pry off the door panel starting from the bottom and working upward to detach any clips.

3. Inspect Door Mechanism

Once the door panel is removed, visually inspect the door latch assembly for any disconnections or broken components.
Check the wiring harness for frayed or damaged wires that could affect the door operation.

4. Repair or Replace Components

If the latch is stuck or malfunctioning, manually operate it to ensure it moves freely.
If damaged, replace the door latch assembly with a new one. Make sure to properly connect all wiring.
Reassemble the door panel by reversing the disassembly steps and ensuring all clips and screws are secured.
