If the battery is totally dead the brake switch will not work, therefore you cant get it out park,,,,great idea huh?
It sounds like the battery has gotton so drained that it may have an internal short, and will not work. I would not trust it at all.. I would suggest just replacing it and have the charging system checked to make sure it is charging the new battery. Autozone or CarQuest will test this for free.
