My 2004 Chevrolet Aveo hatchback has a squeaking sound

Hi Guys, can someone help me with this problem in my 2004 Aveo hatchback?

Here is the video: https://www.youtube.com/watch?v=81cH...ature=youtu.be

I am hearing this sound every time I am releasing the clutch and about to move the car. I think it's when the engine is applying more effort to move the car. like for example moving from complete stop, slowly passing through a humps etc... I also noticed that this sounds is present when the air-con is "ON". When the air-con is "OFF" the sound is almost nothing.

Can someone tell me what this problem is? I will appreciate all your help and thank you in advance.

Its going to be a pulley along the AC belt.; most likely the AC compressor pulley. When the AC is on, your putting a load on the belt and compressor pulley, causing the squeaking

Hi slayerized6, thanks for your answer, That is also my suspicion. Do you have an idea on how to fix it? and is that a serious problem for my aveo?
