On tuesday, my car dash display read "check battery system"?. i was on my way home and pulled over to a nearby parking lot when i lost power steering and the car started shaking/rattling until i turn it off. tried turning it back on and wouldnt start so i bought a new battery and started right away. today on my way to work, i noticed the lights in the dash getting dimmer, then felt the steering wheel getting harder to turn, all my gauges/dials when dead. i was able to pull to the side of the road and turned it off. now the car wont let me start it and i believe it has something to do with the steering column lock since it display on the dash the car with a lock on it. any help would be appreciated.
