Mechanic stated ac compressor is out. That i can drive, but fix soon (which i intend to, christmas i took a big hit in wallet) Turning, i heard metal sound. Sounded like something fell off or i ran over. I parked car 10 min later, walked and retrieved (see images), the items were cold, car warm so not sure if they came from my car. Ac clutch? Driving car, potential damaged to serpentine/timing belts or other components?
