AC clutch makes noise when it is engaged

I have a 2007 Hyundai Tucson. I installed a remanufactured AC compressor and the clutch makes noise when it is engaged. It does it when the AC is turned off and when the AC is on. The noise stops when the clutch disengages. The noise is a whirring sound.

Any help would be greatly appreciated.

If you don’t mind me asking . . . what brand ac compressor did you install?

If the AC clutch makes noise under these conditions, there’s a problem with the compressor you bought.


Still got the receipt?
I’d be amazed if the store you bought the rebuilt compressor from wouldn’t replace it under warranty… with a smile.

Assuming the belt is correctly routed and the tension is correct, replace the AC compressor again.
