99 olds Aurora will not start. Dash just hums.
Battery is good .dash buzzes security light blinks power steering light blinks
Power steering light blinks.Security light blinks .Starter wont engage.
What have you checked so far ?
Testimonial: "Battery is good. Son said diagnostic panel said something about security. Security light sits and blinks and dash buzzes. Power steering light also blinks?"
Well the security system will prevent the starter from working, but the buzzing thing points to an electrical problem, such as a bad connection somewhere. You may need a shop manual to get all of the wiring diagrams to check it out. You would need to know what is coming out of the key switch and what circuits are not hot.
It could even be a dirty battery cable connection.
