After starting my hubbies truck after about a week of not driving it, I noticed it felt as if the power steering had gone out. I had this problem checked out by the mechanic a few weeks ago, and he said that he could not find anything wrong with it. Is it possible that the cold weather has an effect on this? It seems to be OK after warming up, but I don?t wanna take a chance taking my baby girl in it. Whatcha think?
