Squeeky A/C

["John M. Winslow" <jmwinslow@taconic.net>]

I have a 1992 100CS Quattro, 72k miles, and the A/C starts squeeking
when the fan starts blowing cold air for a few minutes.

I opened up the rubber boot and temperature sensor, sprayed WD40 and
then tried graphite and it still squeeks. I can't figure out how to get
to the fan to try anything else.

Is this squeeking common?
Does anyone know if this typically is the motor bearing or the plastic
fan rubbing?

Thanx,
