Q: Battery light on while driving, lost power- water pump and power steering still working

asked by on

I was driving 70mph when I heard a noise like a snap from underneath the vehicle (as if I hit something on the road) then a few miles later, the battery light came on. I drove about 20 miles before the engine started having issues accelerating and my lights started to dim. I managed to make it to a gas station. Never did it overheat nor did I ever lose power-steering. It still starts up fine.

My car has 171000 miles.
My car has an automatic transmission.

You have two serpentine belts: One for the power steering, and the other is for the a/c and alternator. You must have broke the belt to the alternator and a/c.

Make sure the power steering belt is checked to see if it is due to get replaced as well.
