100 milliamps should not kill your battery in 2 days. 50 milliamp or less is ideal, but 100 should last for at least a week. How well is your alternator charging? Does the drain go down say after 15 minutes? 100 may be the computers booting and will settle down after 15 minutes or less. ( the computer memory functions boot up when you connect the battery cable. ( Be SURE to have the key OUT of the ignition and the doors closed. leave a window down so you don't get locked out )

It is most likely the seat control module. Disconnect the seats and then try the test.
