The A/C clutch has been rattling for about a year on the 97 Bonne Ei when I turn on the A/C the noise goes away. I don't have the clutch nor the knowledge to replace it at the moment therefore when the clutch dissengaged I spray it with WD 40 today and the rattle noise went totally away. Will this cause any damage until I have a new clutch and knowledge in hand, let'* say next year? I could spray it with silicone, lithium or other spray instead of WD 40.

Sounds like all you need is to adjust the clutch. Here'* a write up.

Thanks for the info Dan, only problem is I don't have that tool and I don't want to remove the compressor and open up the system since it'* giving me cold air. I don't have much luck with A/C.
Probably should not post this but here goes.
Years ago before I owned the proper A/C clutch pulling tools I had a clutch rubbing on my 86 Cutlass. I knew the clutch was just pressed on and only needed a small gap between the clutch and the pulley to stop the noise.
I picked up a thin bladed putty knife and a dead blow plastic hammer and taped the putty knife in between the clutch and the pulley. I rotated the clutch and taped the putty knife in all the way around.
That was the last time that clutch scraped when the compressor was off.
