  • Ensure the vehicle is parked on a flat surface and the ignition is off.
  • Disconnect the vehicle battery to ensure safety while working on electrical components.
2. Remove Door Panel
  • Carefully use trim removal tools to pry off the door panel, starting from the bottom and working up to avoid damaging clips.
