check the wiring. its probably shot
The main dome light control switch is turned off.
becaus the 2004 Chevy impala does not have automatic lights and they have to be turned off manually
You need to replace the bulb in your lights. The dim lights and bright lights have different bulbs.
Do you have automatic locking hubs on the front axles?
Check the brake light switch.
It can be your switch or the fuse try checking the fuse first.
Dome lights not turning off On my 1995 Ford Explorer, just to the right of the headlight switch on the dash is a vertical switch that has the word dim below it. If this switch has been turned all the way up to the top, all the courtesy lights will stay on. Just move the switch down a little bit towards the word dim and if your doors etc. are all closed your dome lights will turn off.
Your best bet is to go to the junkyard. they are pretty easy to take off and wont cause you a lot of money. or try websites like craigslist, or ebay.
Mine turns on while parked and wont turn off till I start it. Its a problem with the BCM. Body control module.
depending on the year the Taurus lights will either have switches on the sides, or the switch is made into dash dimmer switch. If these switches wont turn the lights off, check the doors to make sure that the door switches operate properly.
That happened to me before, there is a dimmer switch that dimms your gauge panels. you might have that swtich turned all the way up.
