Where is the Dome Light Delay Module ?

Where is the Dome Light Delay Module ?
2000 LS four door.
Sometimes the dome light will turn off.
Sometimes the dome light won't turn off.
After a couple of minutes, I press the dome override and turn them off.
Several miles later, I press the dome override to OFF and the light stays off.
I've tried to isolate each door latch, but it is so random that nothing seems to repeat two times.
Does anyone have a schematic of the delay module and all the connections ?

02' dome lights messed up
Mine aren't working right. When I open the door they come on, but when I put the key in and start up, they're supposed to go out aren't they?....but they don't. So I have to push the dome overide button in, to turn them off. And I'm sick of having to remember to push the button back out all the time when I leave my truck....so they'll come on for security or when I re-enter the truck. But if I do release the button to have them back on.........the bloody lights take forever to turn off. Like 15 or 20 minutes, which is rediculous. Can anyone please tell me what's going on?
Also, pulling on the door handles don't turn them on. Shouldn't they?

If I remember correctly, only the vehicles with the content theft deterrent system would have switches in the door handles. The rest would have the traditional door jam switches.
It sounds like you have a door jam switch problem.

So could be the switch? Ok thanks. I wonder what the dealer charges for those. Anyways............so with a new door switch....the dome will go off when I start the truck? (yes, the DS switch was sticky and wouldn't go out all the way, so I loosened it up with WD4O, but that was months ago).
And I'm still wondering why they take maybe 15 min to turn off after I leave the truck.

If there is a switch that is not opening up properly when the door closes, it can cause the symptoms you are experiencing. The switches close a connection when they extend and open the connection when they get pushed in.

Is there a schematic of the light delay module available ?
Does each door switch go to an individual input to the module, or are the switches paralleled at some place and then a single ground wire goes to the module ?
Answering Tony.......... I think there must be a master disconnect that opens after 15 minutes that isn't part of the delay circuit ( ?? ) Mine does the same thing.

Check out THIS THREAD for a schematics showing the door switches, inadvertent power relay and the courtesy lamp circuits. The inadvertent power relay handles the shutdown of the courtesy light circuit among other circuits, but it is controlled by the BCM (body control module).
The switches are all in a parallel circuit that completes the ground loop back to the BCM. Any damage to the wiring or switch that completes this circuit will cause the lights to remain on.

Annnnd it finally happened, with me leaving the override button out.......so the lights would come on if someone enters my truck (and staying on for probably at least 15 bloody minutes every time I leave the truck)..........stranded at work with a dead battery. Lucky I had JUST put my charger in the back, the day before. Ten minutes charging and I was finally able to go home.
