A/C compressor noise
I have a 2002 Taurus Sport, 3.0 24V DOHC. I noticed an irregular sound when I turned on my A/C.
VISUAL INSPECTION REVEALED: There seems to be a wheel in front of the belt drive wheel on my A/C compressor that was spinning at a different RPM than the belt. But it was intermittent. At some points it would catch up to the belt drive wheel and then slip back down to a slower RPM. The noise came while it was turning at the slower RPM.
Is this a simple fix to tighten that front wheel or does this sound like a more complex problem like a new part?
If this is not enough information, please ask questions so I can articulate the problem better.
