Very Noisy W124 AC, when off!

Good Evening,

My AC unit has become very noisy when off. When the AC is on it is quiet and perfect sounding. When off a high pitched laborious squealing noise. Clearly identified sitting in car with motor running and windows open and changing AC on and off by switching from “0” to the “Normal” position.

Car is '86 300E. 162k miles.

What do I do? Is the pulley/clutching system replaceable? How hard is it?

Thanks, David
