Loose or glazed fan belt?
The squealing noise from your car's AC when you turn it on could be due to a worn-out or loose drive belt, which may need to be replaced or adjusted by a mechanic.
squeeling when turning, generally means your power steering fluid is low. check steering fluid
The belt has worn on the edges and creates friction which causes squealing. Also, sometimes when a belt is cold it will squeal.
the water is entering a moving part that it should not enter and or effect.. make sure your belt is tight and have a shop check your wheels if that's where the noise comes from

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.
You'd have to define "better", and also exactly what you're seeking - we don't know if you're trying to deal with squealing noise, grinding noise, etc. or you want your car to sound more tuned.
More likely the bearings in your alternator wearing out. Get a new alternator.
When a car makes a squealing noise during turns it means that your roters are worn out and you need new ones, bad breaks can cause wear on roters due to more friction heat being pruduced because of the lack of break pad material so you probably need to get new breaks as well.
Check the fluid in the power steering. If it is low the car will make noise when you turn the wheel.
