Truck broken down - electric problem

Hi on my 07, E350, all of a sudden the battery went dead. And the power lock switch is very hot. If I knew where the fuse or relay was, I could pull it and get the van back. But I don't know which it is. Does anybody know. Right now I disconnected the battery so it doesn't get worse.
Thank you.

Fuse #5 30 amp in the underdash fuse box supplies power to the door locks and the power windows. You could try that, but your windows may not work either. But that would narrow down the problem if that makes the drain go away.

I replied to this same member's question in the Full Sized Vans sub-forum:

You can find the fuse locations in the owners manuals which can be downloaded and saved here: Owners Manuals The fuse information begins on Page 170.

I add the RKE Info only because it could affect this "hot switch" issue. If possible to do a voltage drop test across any of those above-listed fuses we might be able to further narrow down which component is causing the problem.
