    After posting the above I did a little more and took out the back seat and found a box called the BCM and it was what I heard running not the pump. I appears this is what is running down the bat. I disconnected it and will let it set all night to check again and I found fuse #21 When it take it out and test for a drain there is none so I hope I found the problem in the DASH cluster I hope.
