Whining noise

[dchum]

my car has this whinning noise recently low revs and high revs and even when car is warm. Its from the front area. I suspect it is alternator, compressor or the pulley. Before I send the car for servicing come January, anyone has any idea what it may be?

Check the belts & tensioners.

Could be a simple bearing issue.
