Re: AC screeching noise / 92 100 CS

If this is more like a whining noise, then it is most likely the secondary
or AC fan. This is an electric fan and only kicks in when the main (belt
driven) fan cannot provide sufficient cooling. Most likely this happens
during city traffic when you do not drive fast and stop a lot. I had the
same problem on my car and had the fan replaced under warranty although
everything worked fine besides the noise. A liitle whining is still left
although it is not as dominant anymore. If you have no problems with the
functionality of your AC I would not touch it.
