Check the serpentine belt. Thats the most common possibility

Belts usually make a squealing or popping sound. I think this vehicle has a wear indicator on the tensioner pulley. Have your mechanic check it. He should also check the tensioner and idler pulleys. The whinning could be a bearing noise.
