I must have left my trunk open and my battery drained because all the lights and power options didnt work. I tried juicing up the battery with my house charger hook up and when i do, the fans turn on without me putting the key in the ignition. The car still wont have enough juice to get it cranking. What would cause that problem?

    The main cooling fan for the engine is a fan hub withe silicon gel in the center of the hub, the fan that you hear staying on is probably the condenser fan. Most likely the fan relay is stuck, it will need to be properly diagnosed before just jumping to conclusions. It's not a complex problem a shop familiar with Buick or GM products would probably charge an hour to an hour and a half diagnostic time to diagnose the problem the time would go toward fixing the problem and would most likely be fixed well quicker than that.
