I have a high pitched whistle noise in the passenger compartment. It seems to be worse when heater or AC is on. This sounds like a possible hard one to diagnosis but I hope you can give me some ideas. Thank you.

You may have asometing stuck inside one of hte ducts or heater itself. You might try taking blower out and looking or feelingaround in there for a foreign/loose object or one fo the floor ducts. Try to see if it whistles all the time or just when in certain areas of flow like floor, defrost etc.

Oh check for vacuum lines disconnected as well as leaking vacuum motors
