'04 Pontiac Grand Prix battery drain

Okay, I've had my car in the shop for over a week. They can't seem to figure out why my battery is draining. It's getting a little frustrating, any ideas? It runs perfect, then it just dies overnight or a couple of days! Help!!!
 




Yup, do that test, but 04+ test the system every so often even overnight so you may have a battery that is on its way out.

I hope not, it's a brand new Interstate battery. :eek:

I just forwarded,
"Parasitic draw test. Isolate the circuit."

Start with the basics. A test light and remove the battery cable. Insert the test light between the cable and the battery terminal you removed it from. If it lights it's drawing power the more power the brighter it will be. Then remove fuses one at a time until you find the circuit that is causing the drain.
