Went to Chevrolet this morning and apparently there is a new bulletin out about the AC whistling noise. They told me they installed a one way valve in the AC or heat line not sure which but the noise is totally gone. finally!

this when you turn on the ac and theres like a little whistle noise coming from the passenger side?

Well I haven't seen any bulletin or PI issued by GM for a "whistle" noise. The bulletin I think he's refering to is the one for the valve that they have been installing in the heater hose for a gurgle/rattle noise. That bulletins been out for a while now.

I have the whistle noise that I hear from my driver side air vent. I don't know if it also comes from my passenger side air vent because I haven't been a passanger in my car yet while it's driving.

I generally hear the noise when it's quiet outside, usually late at night. My car has made this noise for a couple of months now. I haven't been to the dealer for it, though.

Yeah I have that saem situation as well, thought it was just me and it kinda drives me a little nuts at times. I usually just went ahead and turned up the music so I wouldn't focus on it that much but since they are fixing the situation I'm gonna hit it up.

Is this a noise ya'll hear with the interior fan on? I have a squealing fan at low speeds that drives me a little nuts after being in the car all day, and its from the pass. side... but its not a whistling sound.. If I could get them to do it all at the same time, I wouldn't need a radio!

That could be the outside mirror area that whistles.. Mine does that and it can be heard inside the car even with the windows up if I have the radio off.

I also had the heater core gurgling fix done and it worked like a champ.

I hear the exact same noise in my car coming from the passenger side at low fan speeds. Have you had any luck in fixing this?

thanks for any infos

My A/C does the high pitched whistling/squeaking noise whenever the fan's on, but only sometimes. It's directly correlated with the speed of the fan (and is most noticeable at lower fan speeds), so I assume it's a bearing or something just squeaking.

jvc88889 · 09-20-2010, 08:18 PM

Mine is a high-pitched electrical sound, which can be heard at the lowest fan speed. At a medium or high fan speed, I think the sound gets covered up by sound of the blasting air.
It's just sounds electrical, but not really a whistling made by airflow. It's constant whenever the fan is on low setting.

Could it be a resistor or what?

The dealer said they all do this. Going back for a second try this week.
