I own a v6 1999 mustang...its making a whinning sound from the engine at idle and when accelerating the noise went with the sound of the engine, even when i turn on the AC its sounds even louder...do u all think its the AC Compressor cause i've already spent money trying to fix it but still makes the same noise. I read this one forum from here that it could be the alternator and nope i have a new one and i even thought it was the power steering pump but i already got a new one. I also thought it was this one pulley but nope i already have a new one.
any advice? or what else could it be exspensive to fix???
