Twilight Sentinel
I am a little baffled and wonder if any of you have any ideas before I head off to the dealership. My 2001 Vert's GM build sheet says my car is equipped with Twilight Sentinel (option code T82), and my car is a Canadian car which all the Vettes built for Canada came standard with Twilight Sentinel....but in 3 months I have NOT been able to get the darn thing to work.
I do know in the manual it says that you can't toggle the Twilight Sentinel on and off with the DIC in a Canadian car.
Anyone have any thoughts or suggestions before I take the next step and go to the dealership?

I'm not sure why you would want the twilight sentinel. When it does work, it will turn on the lights way too early in the evening, usually just as it begins getting dark. Every time you start your car in the garage, the lights will pop up, probably causing premature wearing of the lights. I have a Canadian C5, I bought a resistor setup that fools the twilight sentinel in to thinking it's always light outside. It's possible that you may have one already installed in yours, because if yours has the regular Canadian set up, you would not be able to disable it. It's also possible that the fuse has been pulled, I believe it is fuse #44 in your car. There is also the possibility that it could have been reprogrammed.
I had the Resistor installed in my first vette. The timer was off so the lights would turn on just from a cloud going over the sun. Gets really anoying after a while.

He should probably pull up the windshield vent and check to see if it's connected. Probably find a resistor in the harness. It's the sensor on the left in the vent.

It is not that I want to use it, I prefer to have it off, I am just trying to figure out why something on my car does not work. I would kinda like for everything to stay in working order until I at least pay it off...LOL
Although I have used it on other vehicles and rather like it, and if I had a C6 with fixed lights I would not care if it was on or not, but not since I have pop-ups...like someone else mentioned, I think it would wear the things out quicker.

i guess i must be the only one that likes it...
in the morning i don't have to flip the switch to turn them on. when i get to work i don't have to turn the lights off. (will they turn off on their own if i forget to flip the switch?) in the evenings on the way home they come on about dusk. sometimes they do come on during the day when i stop at a light under an overpass or in a shady place but the few times it happens is not a big deal.

You turn it on in the Options settings of the DIC. The setting is 'Twilight Sentinel'. You toggle it on and off via the menu.
If it doesn't show up on the options menu, your car doesn't have it.
p.s. I keep mine turned off.
