Whistling Fan/Blower on 4th Gen

HELP: Whistling Fan/Blower on 4th Gen

There is a whistling noise when my fan/blower runs (AC and Heat). Not real loud, but loud enough to be irritating. The noise is louder at higher fan speeds. Has anyone had similar probs…and any fixes out there? I did a bunch of searches but couldn’t come up with anything.

Thx.

Anyone?

Does it sound like you have a supercharger when you rev the engine?

Might be your pulley's.

Funny - I think I heard that noise today and was trying to figure out what it was. If the radio is not on, it will drive you nuts!
