I was wondering if anyone could help me out. When i have my ac on high. i hear a low pitch humming/buzzing sound(when on medium the sound goes away)... Anyone ever heard of this **it??? So weird. I've been having some serious bad luck these days. Recently my sunroof busted. But i got the dealer to replace it. omg!!!!.

Please help

 

come on guys!!!! a little help please.

 

patience....

Where is the noise coming from?

Though the stereo or from a vent??

 

from the vent. when i turn the fan down. the buzzing/humming sound goes away.

 

is it possible a piece of paper or some kinda wrapper might be in the vent?

have you checked your cabin air filter? Maybe something stuck inside?
