My wife's 2003's battery had been dying every morning and my mechanic found a cold draw as well, reading about 6 every thirty seconds or so. We walked around the car listening and could hear a thunking sound coming from the rear window wiper arm area. Removed the appropriate fuse and the draw went away.
The wiper motor had been acting up before then. Turn it on and instead of completing a normal sweep pattern of the window, it would sweep down under the window.
My mechanic is ordering a schematic for the van so he can try to find why there is a draw.
