With my 95 SS I have had the scenario where the interior lights dont go out after the normal 30 sec delay and just get stuck on when exiting the vehicle.

In troubleshooting I thought it was in the twilight sentinel module in passenger side kick panel, but removed that completely and still have the delay. From looking at the schematics in the service manual I cant quite tell. Is it in what they refer to as the "audiable warning" module in the convenience center? or is it the PCM or something else that actually control the delay?

Any advice on overall solutions or culprit also welcome.

Thanks.

Believe it's in the chime module. I have an extra that I'd be willing to cut loose. How's $30 shipped? PayPal only,shoot me a PM if interested.

Mine did same couple months ago. The green module up firewall just needed to be wiggled/reseated in plug. One day the lights just stayed on.
Worked for me hasn't happened again YMMV

Certainly would be worth a try...The modules themselves are not repairable though.

Sounds like we are fairly confident its in the green module? I will try removing it and maybe cleaning the contacts. Problem is it does not do it all the time.

Thanks for the offer 1slow96. I think I am going to give this a shot first but will keep it in mind.

It is the green chime/warning sounds box that controls the interior light delay to off.

I recently found a good way bypass the delay to off,so now it acts like an old Chevy.Close the door lights go out immediately.I like not having to worry about or having to watch until my interior lights go off after 25-30 seconds.

This delay by-pass is very simple to do. Remove the green chime box,pop it open and slide out the circuit board.You will dremmel off pins A10 and A11 as close to the circuit board as possible.I marked the 2 pins in blue marker in a pic below. Reassemble the chime box and that part is finished.

Next make a simple copper jumper to insert into pin locations A10 and A11 in the conv center.I used a piece of 14 gauge solid copper wire,and tapped the ends flat and bent it into a U shape.Size of jumper 1/2"x1/2"x1/2". Finally,plug back in the green chime box so all the audible warning sounds will function.A clean simple no cost mod.

Hmm, I don't recall my 96 Impala having any kind of delay on interior lights, I shut the car off and close the door and the interior lights go off immediately.

Why? Everything's repairable if you have the know how.

Not saying I do lol but still. People used to say the same thing about the ebcm on C5 corvettes. Pre 2001 they would flat out say don't buy the car because they were prone to ebcm failure and there was no fix. Eventually someone figured out a way. Yeah these cars might not be as popular anymore but the affected module is also nowhere near as complicated.

If you know how? Yeah,that's a mighty big if...Especially considering one can easily purchase one for as little as $20-30... Or, find one in a salvage yard for practically nothing...

One of the things that I don't like about the Delay is that when they do go off, they click off right away. I like how on our Grand Prix, you have a delay but instead of just turning "OFF", they will slowly dim and then go off.

I know it's a little thing but at some point I will add a Dim function to my car to mirror what the GP does. There are write-ups on how to create this circuit, just not sure if this will work with the Interior LED's in the car now. It will work with the reg. incandescent bulb though.

the T/S adjustable dial next to the headlight switch adjusts the length of time the interior lights and headlights stay on after you shut engine off and close driver door on exit

I just leave mine on the lowest setting , just above turning the function off completely, so the interior lights go off very shortly after I close door (read almost immediately) but the head lights stay on a little longer. On mine the interior lights and headlights don't go off simultaneously. IDK why...perhaps two different circuit values controlling the two

Pretty sure the Interior Light Delay and the TS delay are 2 separate circuits. I have not looked at the Schematics but I only say this based on the fact that my car never had TS and the Delay Off of the interior lights was present before the TS was added. After the TS install, there was no change in how the interior lights turn off.

IDK if there were any differences in Caprice vs SS trim on the T/S deal or 95 vs 96 year models.

What I did notice on my SS is, depending on where the dial of the TS is at, the headlights and interior lights go off at different times. Usually interior going out first but sometimes headlights going off first. So yeah I assume two separate circuits but one control. Anyway for me I just leave it at lowest setting since it needs to be "on" for the "twilight" feature to automatically turn on the headlights. I have no need for the interior lights to stay on any longer once I close the door

Valid point. At some point they will run out. Though, they made far more 8 bodies than C5's which is what triggered a response when the supply dwindled.

All you need is a capacitor wired in line with the bulb isn't it? I did it once with the first car I ever had. I didn't care enough to do it again.
