My battery went dead because I forgot to close the trunk so the dome light stayed on. I boosted my car with no issues and went for a drive. During my drive (about an hour in) the power steering light came on and I lost power steering. Then a few minutes later, the ABS light came on, then the handbrake light, then the airbag light, then the radio cut out. Finally, all the lights (interior and exterior) began flashing very quickly. I pulled over and shut he car off. It would not restart on its own or with a boost. The car lights up as usual when in "run", but it turns over very slowly and does not start. Does anyone have any idea what it could be? The battery seems to be fine, but wouldn't having a boost eliminate any issues with the battery? Thanks.
