Air cond trouble
2000 C5 with 84,000 mi. Got to Corvette Carlisle and had a bad rattle coming from the front of the engine. changed the idler pulley at the fairgrounds even though I changed them all last year. Still rattles, on closer exam I see metal shavings around the front of the AC compressor clutch and it's quiet when AC is on. Looks like bad clutch. Can this be changed on the car or should I just change the whole compressor ? It still cools fine!

AC Clutch
Hi, I wouldn't say it's impossible to change the ac clutch assy on the car, but you would have to remove other components to get to it with the specialty tools neccessary. In the end it would be so easier to take the comp off the car, and either get a reman, or change the clutch assy on yours. Below are instructs on how the service manual recommends doing it.
Good Luck.
