I pulled the trunk light out. Still drains.

On the 02 models the rear window defroster often did not time out & turn off. This could be a possibility.

This topic has been discussed at great length already. Your best bet is to start on post one in this thread and the one below and read each post. For example, one owner found out burned-out map lights were their problem because the map lights were turned on but the bulbs were dead so he didn't know.
