I have a 2006 4 cylinder 2 wheel drive that the power steering has gone out. I replaced pump and rack. No good. I checked pressure hose at both ends by loosening them and got fluid enough to drain the reservoir. How much should I see? I pulled the pressure switch wire and jury rigged it back in place and I don't think that is the problem. There was crud in the reservoir, could the line be plugged? I can't figure the next place to go with this.
