Hi all, Recently about 4 weeks ago, the power steering went on the car, it was brief and returned to normal after 10 minutes. This happened intermittently until 2 weeks ago when it stopped altogether. The steering is very stiff to turn the wheels and im hoping its not the pump. i have only checked for leaks and fluid levels so far, no visual leaks and fluid levels are fine. what else can i check before taking it to a garage, i hear a lot of the steering issues can be down to battery or alternator, the battery was changed about 10 months ago so could it be the alternator or the pump/rack and pin? thanks for your time.
