My '04 Mach 1 decided to eat its belt last night. I took it off (thankfully it hadn't snapped yet) and tested the pulleys, they all seem ok. I replaced the belt and it hasn't shredded that one yet, but the ac compressor is acting weird. The ac works just fine, but when it's off the clutch hub spins slowly (maybe like 15-20 rpm) and erratically when the car idles. If I hold it around 2500 rpm, it doesn't spin at all. There was a bunch of shredded belt wrapped up in the hub, I pulled out most of it but there's still some stuck where I can't reach it with pliers. Could the shredded bits of belt stuck in the compressor be causing this, or is it more likely the clutch starting to go? I should also add that the car is procharged, which may have contributed to shredding the belt if it wasn't the compressor.
