'98 Olds LSS, 3800 N/A.
One annoying squeak has been tracked down. With the engine running and the A/C off (it doesn't seem to work anyway), I can see the A/C clutch turning slowly with it's pully. Not at engine speed, it lags behind quite a bit. At one point of it's revolution it squeaks, once every few seconds or so. I can touch it with the handle of a breaker bar and keep it still with no effort which silences the squeak. Turning the A/C on does absolutely nothing. I had attributed that to a low/leaky system but maybe it's clutch related. So two questions: How is it even possible for the clutch to behave in such a way, and how do I shut the damned thing up?
