Courtesy lights timer
Greetings all, On my '92 Vette the courtesy lights stay on all the time even while driving. I assume there is a controller somewhere for this. It also controls the electronic climate controls and the stereo. Can someone please point me in the right direction on this?
Thanks for your help.

Not an expert
Hey - I'm not an expert 
but this "sounds" like faulty door switch on either one (or both - maybe) of the doors.
If the door switch doesn't see the door closed, then the interior lights stay on and, pretty sure that the radio probably won't work either. Not sure about the climate control.
Hopefully one of the more "learned" forum folks will respond with better info.

More than one forum member has reported having to shim the door switch(es) to get their lights to go out.

Check to see if radio shuts off when you open either door, if it does the jam switches are ok. Next check to see if the the door lock key slots are oriented vertical, if not that is your likely problem.

That's the first time I've heard about the key slots being vertical - that's pretty wild.

Chased that one on my 92 for a while before I figured it out. The FSM diag tree for that failure talks about the keyswitches needing to be eliminated as a failure before doing all the other diag stuff, but they don't mention the slots just need to be lined up vertically. When I have this problem, I just sweep trhe locks both ways a couple of times, make sure they are lined vertically when I remove the key, and all is well.

Not a solution to your problem, however , to answer your question on controller. The CCM ( Central Control Module ) buryied deep in the dash controls almost all electric/electronic features. It turnes off the courtsey lights in 10 minutes if the door is left open. I won't turn them on if the light sensor signals it is too bright. I also controls the odometer reading, oil change light, A/C & heat, your switches that toggle the readings on the dash plus more I can't think of now.

Thanks guys, I checked the door locks and moved them around, so far no difference. I will 'sweep' them like scrange said. It does seem to turn them off sometimes. I do get a CEL with a code 26, relay control. Might be related to the CCM. Snow today so no Vette driving.

light staying on or off
It may be your rear hatch striker that turns off the light not making contact. I had that problem with a '93 and again with a '96, both coupes. I use the little add on to let air into the car while it is parked, raising the rear hatch about 1 inch. After time it does not make contact with the oin.
Try that, may work. If a ragtop then I'm lost.
