It seems to me that the best way to diagnose this is to check the diodes in the circuit, and separate the circuit into sections to track down any short to ground. Where in the car do the two wires splice/join in the two halves of the door lighting system (ground)? ANY help appreciated.

Up until a few days ago they worked fine, went off with the door switch normally. Then they stayed on one night, I charged the battery back up and pulled fuse #12 and they went out, fuse back in and they came on - no surprise there. Then I pulled both wires off the back of both door switches until I had time to replace or repair the faulty door switch - and the lights stayed on. I looked at the wiring diagram and realized that I must have a faulty light delay module, so I pulled it out. With that module (the white one) out, and both door switches unplugged, the lights were still on. I assume I have a bad diode or two, but where else do I look for a short to ground, which I assume is the problem. Fuse #12 sits lonely in the ashtray tonight, waiting for its chance to be reinstalled, please help.
