i was driving when all of a sudden my power steering packed in. i have checked my fluid levels and they dont even leave a mark on the dipstick.

i assumed this was the problem but i am jubious as it stopped very suddenly. any ideas what the problem could be?

if it is the fluid, how do i go about buying fluid and putting it in?

thanks

 

i dont know if it would stop all of a sudden but PAS pumps are well known for leaking,
