I was a victim of the leaking firewall grommet and the passenger front seat floor got flooded. This was about 10 months ago, but I think this issue I am having is a result of that.
Its a 2009 g37s. My battery drains often and frequently (need to jump it every other start). I think the issue is the bcm. When the car is completely powered off, I sometimes see the key icon flashing on the dash and hear a clicking (see videos below). The clicking appear to be coming from inside the bcm. Everything works on the car, except the battery draining. Does it sound like the entire bcm needs replaced, or is there some module or just part of it that could be related to the key icon flashing where I could just replace that? When I unplug the green connector seen in the below photo, the clicking stopped (maybe that's because I am killing power to it though)
below is a video of the clicking sound

and this is a video of the light on the dash blinking

any suggestions where to get a bcm without dropping $800.
Thank you all very much for reading and any thoughts are appreciated.

1. Is the light on the cluster really flashing that fast?
2. Can you confirm 100% that the clicking is coming from the BCM? A long screwdriver placed on the side of the module with your ear to the handle will help to confirm.
3. Are there any codes?
If either #'s 1 or 2 are true, then more than likely the BCM will need to be replaced. Keep in mind that replacement WILL REQUIRE syncing (programming) to your car.
