Interior lights problem 05 Montana

[Starcar33]

I have a 2005 Pontiac Montana the interior lights quit working I know it has a delay but no clue where it is

When you say lights, I assume there is more than one and you made sure the bulbs arent burnt out?
You made sure somebody didn't move the switch to off?
The dimming function maybe controlled by the BCM but you would have to refer to a shop manual to determine what component causes the dimming. I can't find a delay module.

Once in a while they will come back on then they quit working again the delay function causes the lights to go off slowly about 30 seconds to one minute after the door is closed
