Are non working interior lights/dome lights a common issue in gto's? Since I bought my 04 gto I've never been able to get my interior lights to turn on. Dome lights and door lights are the ones that aren't working. Dash and ac controls work fine.My glove box light does work when open, and so do my dun vizor lights. When I open a door the interior lights don't come on. When I manually override the lights with the switch on the dome light nothing happens.
One day I took the dome light down and used my power probe and provided 12v to one of the leads on the dome and it lit up, so i know the bulbs aren't bad. So far I see there isnt power present on the dome at all everything has ground. Interior illumination fuse works as well as the interior illumination relay which also controls the headlights. Im lost at this point and don't know where to look next.
It doesn't seem like a short because fuses are all good
Im wondering if this is a common issue with our cars or if it was something the previous owner did.
Hoping to get out of the dark, let me know what y'all think it could be.
Thanks

The only thing aftermarket in the interior is a touch screen radio. That radio has been acting up since I bought the car too, my stations reset themselves constantly and sometimes they stay saved for a few days.

I checked ALL of my fuses with a power probe, same continuity on both ends of all fuses, even tested all of the relays in that fuse box, ALL are good. I just need to find where the power goes after the relay. perhaps the lighting circuit is tied in like christmas lights and if one point is broken, everything else goes...
Im gonna do a search on the bcm next thanks.

Thanks, ill have to try that in the morning. btw, i found some body control module connector diagrams and i see that it controls a lot of things including my interior lighting. i was wondering if i unplug any connectors will it loose any programing? I don't want to have to send it out to re-program.

Yeah I know about the common bcm issue where it rubs against metal. I looked under there, not too hard though and didint see anything out of the ordinary. I’m gonna check again today a little more to make sure no wires are grinding.

The BCM will stay programmed without power.
Keep in mind that a lot of these cars had electrical gremlins and many owners replaced parts themselves...that being said, if a BCM was replaced and not programmed to your VIN you will have other issues.
I would first look at the door switch and wiring and then the dash switch.
