How do you replace the driver's side mirror on the 2004 Toyota Sienna?

To replace the driver's side mirror on a 2004 Toyota Sienna, start by carefully removing the interior door panel to access the mirror's mounting screws. Disconnect the electrical connector if the mirror is powered, then unscrew the old mirror from its mounting bracket. Install the new mirror by reversing the process: secure it with screws, reconnect any electrical connections, and reattach the door panel. Finally, test the mirror's functionality before finishing up.
