I think the high-drain accessories automatically cycle or shut off temporarily if the voltage in the system is too low. It says that in the owners manual. Might have been your issue. Too much load on the alternator at low-rpms so you had voltage drop. Seat heaters + rear window defroster + the car's ignition system + fan etc....is probably well beyond the low-speed output of the alternator.
