Sounds Like a Siren

courtesy of Bob, The Auto Answer Man

Dear Bob:
I own a '89 Bonneville LE. Lately, I have been noticing a siren like sound coming from about the center of the engine more to the passenger side. This noise has been increasing when I step on the gas. Also, things seem to get a bit dimmer until I step on the gas! The power door locks have not been working properly and the power windows seem to move very slowly. There is a new battery and the belt seems fine. Can you help?

It very well could be the bearings in the alternator that are squealing. Does the pitch or the volume of the sound change as you increase engine speed?
Good Luck!
Drive Safely!
