Hey guys, I need help finding a rather large short. After waking up to a dead battery and stinky cabin after a large rain, I took the battery out and charged it. I know there is a water leak because the cabin is stinky and I've found moist spots in the headliner. This is my wife's car so I have not had my eye on it. I only hear about problems when they result in a disabled car. Anyhow...

When I put the battery back, I got a large pop and arc on the negative terminal. So much so that I can't put the cable on. It's melting the lead on the battery.
I then took out all the fuses and relays from the front and rear SAMs as well as the dash to hopefully isolate the draw. I also disconnected a few of the cables in the front passenger compartment circled in the image below. I then put the negative cable back on the battery and I still have the very large draw.
I also inspected the battery control module in the trunk and it was fine.

I ran out of time so I haven't done more.
What else could be pulling this much power?

what battery cable did you connect first

Positive

the answer will be obvious once you pin point exact source with your detective hat on

You have a hard short-circuit after the car got rain soaked from a roof/ windshield leak.

See where water penetrated before it gets dried. 85% chance it won't fix itself by drying.

> Choices are ....
OCP Module sunroof buttons.
Passenger footwell modules.
Engine hood main power Front-SAM.
Driver footwell ....
Front seats 2x modules ?

Is the big positive cable that connects to the Pre-fuse ok? How about things in the trunk?
