Dead battery - interior lights won't turn off

Yesterday I found my 2003 TJ had a dead battery. After jumping it, I discovered that the interior lights would not shut off. More than a month ago, I inadvertently left the Jeep door open while working on it in the garage. When I saw it the next morning, I was happily surprised to see that the battery was intact and that the Jeep had shut the lights off after 20 minutes to save the battery, just as the owners manual says it will.

In trying to trace the issue, I have done the following:

1) checked the multifunction switch was actually turned off, it was

2) removed and disconnected the multifunction switch to see if it was the issue, it wasn't

3) tested the door switches, by removing fuse #4 behind the glove box, the lights still didn't go out.

4) pulled fuse #26 in the power distribution box (engine bay) the all accessories fuse, they went out.

5) I even unwired a winch that I had installed direct to the battery last weekend and that did nothing too.

6) reset the computer by disconnecting the positive terminal of the battery, held it to ground for a minute, reinstalled the terminal, turned ignition on without starting the engine, turned headlights on and then off. Nothing, the lights remain on.

Any ideas?
