On Monday the dealership called saying it could be the $1,000 BCM (Body
Control Module) because the vehicle was drawing 6 amps with the key
OFF. The tech was trying to find the short or whatever that killed two
batteries. He was having to do it the old fashion way * one circuit at a
time. The service writer called back at the end of the day saying the
new battery was okay that it charged fine and the tech found the
interior lamp ON so he turned it OFF. The excessive current draw stopped
but he wanted to let it sleep over night in his stall and check it in
the morning. They called Tuesday and I have the car back. For only
$114 we went from Intensive Care to Release.

I have no idea how the interior lamps got turned ON but it was dying on
me during the day and I probably never noticed the lamps staying on.
The lamps turn ON when you open the door and they stay ON when you
close it for about 30 seconds. The same set of lamps double as Map
lights with two ON/OFF buttons in the mirror. I do not remember turning
on a map light but may have done by accident the last time I washed the
car and cleaned the mirror. The last wash was the morning before all
this crap started.

Dodged an expensive bullet on this one. The real test will be to see if
it starts after spending the night in our garage
