Sounds like the bearing are dry or worn , Spray with wd40

In my opinion, the problem is the blower motor. The bearings or bushings are wore out.

sounds like you hooked up battery backwards and cooked the wiring. why were there blown fuses? make sure it is connected with the +to+ and -to-.

Hello. I want to know more first, does it only make noise in motion or all the time?

You most likely have a wheel bearing going out. Try to identify which is squeeling. As these go you will notice a rust film on the wheel rim and the side of the car that is going bad.

I AM ASSUMING AIR CONDITIONING FAN RESISTOR FOR BLOWER MOTOR SPEED
IF SO IN PLENUM NOT FAR FROM MOTOR USUALLY UPSTREAM

It's very possible the fan motor has quit. The squealing noise is caused from motor bearing failure. As the bearings wear out or dry up the motor is harder to turn and require more current to run the motor. On lower speeds, the motor runs off a series of resistors that reduce the amount of voltage and current so the fan runs a lower speeds. If the bearings are worn, there is not enough voltage or current to turn the motor and that's probably the humming noise your hearing.
Good observation by the way.
Let me know.
regards,

Belts stretch from new. Try to tighten them again. Hopefully the are not glazed or this may stay with you.

If the noise going away every time u turning off the ac it's probably your ac compressor belt.however i will suggest to take some vaseline and rub it all over the exposed parts of your drive belt.
