Check your tranny fluid

The whinning noise is coming from one of the Pulley's

Idler pulley? That would mean the bearings inside the pulley are gone out. Easy replacement

Cheap part

Check the idler, If it doesnt seem rough, Check the A/C compressor,put some dish soap on the belts when the motor is shutoff, then start it, see if it stops whining for a short time, if it does, change the belts. If not then keep removing belts to eliminate each component.
