I have a '93 fleetwood brougham and the serpantine belt just started making this sqeeling sound what could be causing this guys? I had a '94 deville that was doing this and it turned out to be the belt tentioner. My belt looks fine like brand new,i took it off tonight and sprum each pully and they all spun freely. When I turn my a/c on if the car's been sitting it makes a rattling sound then stops after a few minues,could this have anything to do with this noise I'am hearing? Isn't there a way to add oil to the inside of an a/c compressor,could it need oil? Thanks for anty help guys.
