I am just wondering if u are having the same problem as me, my did the same thing last winter...If i didnt start it 4 a day or 2 the battery would be dead(and my windshield wipers would go on)I got a new battery and it is doing the same thing this winter. They checked my alternator and said it was fine I am gonna take the battery 2 auto zone tomorrow and have it tested,but I think it is something else |
