Last October I went on vacation and left my car at my mothers for the week. came home and it was dead. Put a new battery in and it was fine. Then the nights started getting colder. I would have to jump the car every morning depending on how cold it got. The winter ended and the car was fine all Spring and Summer. The winters are cold here in NH and I am finding myself starting to need the car jumped every cold morning if it got below 35 degrees out. what is wrong? Is it a faulty battery that only works when it is warm out? The dash display all of a sudden stopped working too. Then with the first jump of the 1st cold night, it display came back on (with my husbands key). These places that I call tell me to bring it in and won't talk to me because I am a woman. Any help would be VERY much appriciated!
Thanks!

You will have to get an AVR check on the starting/charging system. I would be particularly interested in the static current draw test. This checks the amount the car is drawing when the car is powered down. It will tell you if you have too much current draining the battery. Such things as lights left on, glove box lights not turning off, truck light not turning off or modules that are not powering down. If you have things plugged into the acc sockets, this will do the same thing. These cars should not draw anymore than 25mA after the car goes to "sleep". If there is a draw, get them to find it and that will tell you what is wrong. There is a possibility that the new battery is no good as well and this test will find that.

Sounds like the battery has a weak or dead cell causing it to go dead in cold weather. Take the battery back on a cold morning and get it replaced.

I was about to say maybe your alternator is acting up, but it seems to me you may need to keep a battery charger attached to your battery at night if you can do that where you live. I too have a 2004 Grand Prix but havent ran into that problem

Sounds like you need a new battery. Just because it is new doesnt mean it is perfect. Most batteries will come with some sort of a warranty that will allow you to have it replaced. You should be all set after that.
