Alright when it only works on high speed, then usually the resistor between the controls and the blower motor is bad because the default if on is at high speed so I would replace that first since it is much cheaper than replacing the blower, then if the blower is still making a bad noise, it is wearing out and needs to be replaced too. Both of these parts are under the dash on the passenger side. If you want a diagram, then I advise buying a Chilton or a Haynes manual from a local auto parts store especially if you plan on fixing it yourself. Let me know if you have any further questions.

Might be a vaccum leak in the engine.

SOURCE: 2002 Olds Intrigue GLS makes a high pitched

that sure sounds like a vacuum leak ...the vacuum is highest when you let off the gas or at idle.. its lowest when you "give it the gas" ... you can use a small hose from your ear (or stethoscope) to listen to areas around the engine to find where the noise is coming from... check for a loose fan belt also ...check for cracked vacuum hoses .... if you suspect a bearing making the noise ... you can spray a little oil onto each bearing until you hear a difference in one ... in fact the noise might go away if thats the problem ..

is it coming from the wheels?? If so, possible worn wheel bearing.
