Re: AC clutch malfunctioning sometime when AC is ON Quote:

Is the diagnosis of Mechanic is correct?
The car has run 174KKms and yes the Cooling is Very Good. |
1.To test the Clutch - Remove the ac drive belt and try to rotate the outer pulley. It should spin freely. If any resistance is felt then the clutch is faulty.
2. A/C compressor engaging after 15sec- It could be faulty A/C clutch.
Remove the two pin electrical connector going to the clutch, ask someone to press the ac button while you check for power in the connector as soon as AC is switched on by using a Digital multimeter or a 12v bulb with a holder and wire.
Most probably the bearing of clutch has worn and hence the noise. |
