Welcome!! first thing to do is check the S/C oil,theres asmall plug on the top of it...these things often get overlooked..you might even want to change the oil in it..theres a thread on here showing how to do that..
thanks. Ill go pull the plastic off and take a look. is there special fluid? hopefully its no the SC that is whinning (sounds like a bearing in a pully going bad)...
