lately there's been a lot of raining a a lot of water on the road i mean like almost to the bumper water. after a while i noticed a sound, its the same sound as when car is running out of power steering oil. the sound is very loud it sounds horrible, the thing is that the sound goes away when i turn on the ac. it goes way down it still sounds but u gotta be paying attention. could this be that my power steering pump is dying on me?
