The squealing noise in your car when the AC is turned on could be due to a worn-out or loose drive belt. The belt may be slipping or not properly tensioned, causing the noise. It is recommended to have a mechanic inspect and possibly replace the drive belt to resolve the issue.
It's going to be your radiator fan clutch. Mine was squealing for a while until finally it turned into clanging. It was pretty bad. I'm in the process now of replacing mine. That should be your next step.
The squealing sound you hear when your car brakes are wearing out is referred to as a "squealer." This indicator is a strip of metal that when the brake pad wears down makes contact with the rotor making a metal on metal noise.
Loose or glazed fan belt?

Loose or worn belt(s).
More likely the bearings in your alternator wearing out. Get a new alternator.
Water from the road has splashed up into the engine serpentine belt causing belt slippage that makes a squealing noise. The sqealing is one of your engine assessories that use the serpentine belt to drive it.
It sounds like the fan-belt is slipping.
id say check the belts. not a car expert though
It is the starters breaks after it finishes starting the car. It is normal and it is ok.
it could be that your brakes are dirty or that you need new pads
Thee fan belt is loose or dried out. Most likely loose.
