My cars been squeaking for a couple weeks and I dont have power sterring when I turn the wheel. Finally on saturday my serpentine belt snapped and we replaced it. 2 days after that on Monday my car started squeaking really loudly again and I wouldnt have power sterring when I turned the wheel. Then today my car stopped holding a charge to the battery and it completly died. I put a new battery in it and it worked for about 10 miles. Why isnt my alternator holding a charge?
