1. Anyone know a source of discounted wiper blades for our XCs? $50 + a pair seems a bit steep.<p>2. Power Steering. Had driven for an hour or so, stopping several times and shutting down each time. Then once upon starting the power steering acted like the belt was slipping or the fluid level was low. Intermittent assist when turning and the feeling of something not right. At the next shut down checked the fluid level and belt and everything was fine. Belt was not glazed or slipping, certainly no belt noise. The issue was continous during the period from the start up to the next shut down, about 1/2 hour. Car was stopped for about a half hour and upon starting the following time the problem was gone and has remained gone ever since. The car is a V8 and I know the V8s have speed sensitive power steering, but this is a new one. Like i said, it's only hppened once. Any ideas? I'd like to know what to look for if it happens again.
