May have to be turned off manually Auto sensor bad
Check to see if the interior lights are switched "ON" Sometimes they get turned on when you move the headlight switch.
There is a light sensor located at the top middle of the dashboard, near the windshield. This will turn your lights on automatically if the lights are not manually turned on. However, if you drive under some street lights or a bright area, it can read this as daylight and turn the lights off. To avoid this, always make sure that your lights are manually turned on at night. This sensor also effects the interior lights. They should not automatically come on during the day if it is working properly.
becaus the 2004 Chevy impala does not have automatic lights and they have to be turned off manually
The dome lights work automatically and manually. If you have manually turned on a dome light, you must manually turn it off. If it was turned on automatically, it will automatically turn off. On my 2005 model, there is a dash switch to select(Manual)On/Automatic/(Manual)Off. This switch works on all dome lights but will not turn off an individual light that was turned on (pushed in)individually. If you have a passenger that has turned on a dome light, you/they must turn it off manually. Children are particularly prone to leaving individual dome lights on (and it doesn't even have to be dark out), so you should check periodically to assure that your battery is not drained.
If you turn up your interior dashboard light settings, then the radio display will be brighter too. The radio dims to the setting for the dashboard when the lights are turned on.
Perhaps you turned on the interior lights when you were adjusting the headlights?
pretty easy really, make sure your interior lights are not turned on. Your headlights control should also be the interior light controller. Turn it clockwise or counterclockwise to turn your interior lights off. You'll run your battery down if you dont
You probably turned them on by accident. They are controlled with the same pull switch that turns on the headlights. By twisting the switch to the far left it will click and the dome lights will turn on, by twisting it to the right it will turn off the interior lights and will then dim the dashboard lights.
Under the dash on the drivers side there should be some relays (black square). Check your manual for where the interior light relay is. The problem is most likely the sensor on the sliding door. Good Luck.
In a 1997 Lincoln Continental : To the right of your headlight switch in the dash is a ( panel dim ) switch I believe if that is turned all the way up then the interior lights will come on
