Have you pulled all of the fuses while watching the meter? A 107 Ma draw is too much. Almost sounds like a bulb. Check the trunk bulb, glovebox, etc. The BCM and most other modules need to power down. This can take up to half an hour, depending on the module.

These can be hard to find because some modules go to sleep, then wake, then sleep, so setting the meter to the MIN/MAX record function is a real help.

I have seen Onstar modules do some strange things and draw the battery down.
