my power steering lite came on ando then I had no power steering.

sounds like an electrical issue with the electric steering motor

I had problems with my power steering ... i took it in to the dealership they charged me and arm an a leg 1000.00 ... anyway later i had the same problem but i read up on it and found out it was a fuse i had to replace, that cost me 5.00 dollars. Try to replace the first fuse in the fuse box under the hood.
