If it IS the timer module, it's made of unobtanium - they're almost impossible to find. It's located under the dash on the passenger side next to the ECU and is a small black box about 2" on a side with a tab on the back to screw-mount it somewhere (although all the ones I've seen have been taped to a wire sheath). However, usually when those modules fail your center-console hatch button won't work either.

Have you looked at the door switch? It's very possible that it's gotten corroded inside and isn't breaking contact when it should be.

I'm putting my money on the timer, it's acting exactly the way my '85 did. Jay at Vette2Vette has good used ones, he tests them before sending them out. (815) 673-6200

You're both right, they came in both colors.

The Courtesy Light Delay Module is a small module, about 2" square, located behind the passenger side dash panel (bread box) and typically taped to the harness. The old 1985 module part number is 1408-0625. A GM specified alternate part number is 1009-8435. However, neither of these parts are readily available.
These modules are pretty hard to find. If you do a search, there are many posts here on Corvette Forum about how to bypass your timer if it is bad (it'll work the lights just fine, but without the delay), and how to repair these units by replacing the circuitry components inside using Radio Shack parts.
You could also try vette2vette for a used one. I picked up one there recently.

Original part # - 1408-0625 (discontinued)
Alternate part # - 1009-8435 (no longer available)
