How do you get the interior lights on a 2002 Chevy impala to turn off when it is turned off?

To turn off the interior lights on a 2002 Chevy Impala when the vehicle is off, ensure that all doors are fully closed, as the lights can stay on if a door is ajar. Additionally, check the dome light switch, which may be set to "ON" instead of "DOOR" or "OFF." If the lights still do not turn off, there may be an issue with the door switch or wiring that needs to be addressed.
