Help, My Dad has a 1993 Fleetwood Brougham with factory alarm, now that winter has hit here in Ohio his alarm has started going off in the middle of the night, then when he gets to his car his car battery is dead. Where would you think I should start on it? Will the alarm go off if his car battery is going dead?

IVe been reading different posts just trying to get some advice on which direction to start at.

Thank you
