Default battery going dead...

hey, i have a 94 bonneville. And two days ago, tried to start it, and it wouldn't start. It was a dead battery, so i charged it. But it has done it 3 times now. it loses charge over night. So what would be drawing that much power? any ideas?

Doing a search on parasitic drain will give you several threads. Here are two to get you started.

well, i'll give you some more background on it. its actually my dads car, so im talking for him, haha. We have command start, but when you try and start it, the trunk opens. The antenna won't go up, and the radio doesn't work all the time. The cruise control is iffy also....ugh. What is its problem?

We'll start with the battery first, and work on from there. Using the procedure in the threads above, check the current draw from the battery. From what you're saying, the first place to check would be to disconnect the antenna power to see if that drops the draw. If it is broken internally, the motor may continue running, killing the battery.
