So I hop in the car this morning and drive 15 minutes down the freeway, nothing unusual there. I then stop at the grocery store and run in to grab some lunch for the day. I get back in the car, start it up and then I hear "it". A fairly loud high pitched whine that follows the RPM that can be hear at idle and at speed. Google tells me that my power steering fluid is probably low. I pop the hood and the reservoir is full all of the belts seem fine. I have not had much time to check anything else. Any ideas? I am thinking the power steering pump, ac compressor or something powered by the belts is going to fail sooner than later.
