You know, you think google can answer any question until you try to find a power steering diagram for your car.
I’m kinda stuck in Livonia (at the castle) with no power steering, no answer at the dealer, and very little understanding of what to look for in the car. Whee!
EDIT: Uhhh…. it fixed itself?

LIAR! I fixed it!
Err, Randy and I fixed it!
Is it your serpentine belt?
That pretty much runs everything. Mine slips a bit sometimes and until it catches it feels like I’m riding with no power steering.
I was going to say to check the tensioner pully and the belt, followed by the level of pwr steering fluid.
It seemed to be taut enough.
Your power steering fixed itself? My car has been parked all month with the same problem…maybe it’s given up hope and done the same by now. :P
I bet google didn’t predict that outcome. quick! update wikipedia!
