This Morning When I started the TB I heard a Faint Sort of Grinding Noise.. Then after a few seconds it Stopped.. Didnt have any Other issues Until I got out of Class and started it up again.. heard the same thing.. but again it stopped .. got driving gown the road I decided to turn everything off to see if I heard it while driving.. I did. So I parked Turned the AC Off Opened the Hood.. The Noise was Deff Comming from teh Compressor or at least the Pulley for the Compressor. Seemed to Muffle a little if not mostly go away when I tun the AC Back on.. AC is Cooling maybe not as good as it should But Deff need to know if i need a new compressor or not.. Plus this sounds aweful..lol
