On a weekend road trip my compressor started squealing between cycles. It makes noise when the compressor is "off," indicating a bad bearing or clutch surface in the compressor clutch. Does anyone know where I can get a compressor clutch for our cars, or if there are rebuilders? I think it's a Denso 247300-3260. AC is ice cold and the compressor is fairly new (1.5 years old) so I certainly don't want to replace the entire unit.
