I know this thread is quite old, but I thought I'd update you guys on what I think it might be...
I'm going through my dash, trying to figure out why my power door locks and power seats aren't working, and why my car chimes like the lights are on, with no keys in the ignition... so.. I found a second unit connected with the twilight sentinel... and it was quite severly melted... it is below, to the right of the column... and the plastic housing was extremely melted, and the heatsink for the diode was so hot, it desoldered itself from the board, along with the diode itself.. the circuit board was burnt beyond repair... like I said, I'll post pics when I get home..

Ok, here we go with some scary pics..
Well, there you have it... I thought you might be able to see the disoloration on the heatsink for the transistor, but the camera didn't get it at that angle... but yeah, that is incredibly scary... I thought of this thread as soon as I seen that box...
It is the Twilight Sentinel Module.. and the transistor overheated, I would think because of them using a piece of tin for a heatsink instead of aluminum or something more conductive...
Oh, and for the record, it is located below, to the right of the steering column, behind the metal cover under the column, hence why I would think that the plastic cover panel stayed in-tact..
