If there is power lost, lights that dim and a battery light that comes on there is most likely a connection that is loose somewhere. It would be best to check the alternator or battery cables.
possibly
no
probably a short circuit in the steering column. that means a new wiring harness ($150-200 + ) must be done soon, or could cause battery drain, or even start a fire.
no because power steering is a hydrollic assist system
Dead cell in the battery or the ignition or lights were left on.
water in the wiring or a low battery
A short in the wiring.
A loose battery cable can cause your vehicle to on most stall and it can cause the lights to Flickr. Make sure your battery cables are tight and free of corrosion.
If you have no battery then you have no power.
No. A bad battery is not causing your dash lights to go on and off. A different part is bad. Without equipment I have no idea what it is.
Because whoever told you that a low battery would cause hard steering is an idiot.
It can, if you leave the lights or flashers on too long.
