Standard Procedure - A/C Clutch Inspection
WARNING: This page is about a different car, the 2015 Fiat 500. However, it is still accessible from the selected car via links, so may be relevant.
Examine the friction surfaces of the pulley and clutch plate (2) for wear. The pulley and clutch plate should be replaced if excessive wear or scoring is found.
If the friction surfaces are oily, inspect the shaft and nose area of the A/C compressor (1) for refrigerant oil. If refrigerant oil is found, the compressor shaft seal is leaking and the A/C compressor must be replaced.
Check the pulley bearing for roughness or excessive leakage of grease. Replace the pulley and bearing assembly, if required.
