I have a 98 Park Ave Ultra and when the A/C is not running the compressor pulley and the clutch are scraping together. The Clutch engages just fine and the A/C works great but when it is off that scraping noise comes and goes. Do I need to change the whole compressor or is ther an adjustment that can be done?
Optional Information: 1998 Buick Park Avenue 3800

Nothing yet, keeping the AC on all the time.
