Why is my harmonic balancer squeaking?

if the squealing only occured when the car started it would be more likely a water pump bearing. If it only occurs when you enage the AC then it is a compressor issue. A harmonic balancer reduces vibration by allowing some slipage between the belts and the engine. It also absorbs woble.

How do you know if your harmonic balancer is bad?

If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively. The shaking will become even more pronounced, and therefore dangerous to the engine at high speeds.
