Another thing to consider. Have you ever changed the tensioner? The next pulley after the compressor is the tensioner. But at the same time if the compressor is hard to turn (going bad) then it will cause your belt to squeak.

Also on the back side of the belt is it dried/cracking? That's a sure sign to change your belt.

IMHO
if you AC cycles a lot you should be able to hear and identify it as the source and it's usually because a pressure switch
is making breaking a circuit do to a charge condition

Ride around with the a/c off. Do you hear it then? If you want to be sure it stays off just unplug the low pressure switch on the accumulator.
