How do you replace a door lock assembly for a Ford Festiva?

To replace the door lock assembly on a Ford Festiva, start by removing the door panel to access the lock mechanism. You'll typically need to unscrew any visible screws, then carefully pry off the panel using a trim tool to avoid damaging clips. Once the panel is off, disconnect the wiring harness and remove the old lock assembly by unscrewing it from the door. Install the new lock assembly by reversing the process, ensuring all connections are secure before reattaching the door panel.
