During cold months not as much a problem, whether the ac or heat is on/off I hear a whitle sound ( Like a ballon releasing air/ whistle ). The faster over 70mph I drive, the louder the sound gets. Driving me nuts!

Do you
have the same problem?

Check for leaks near and around the heater core (HVAC box) under the dash and under the hood along firewall.
