AWOL

Its not the supercharger chirp, it sounds like its coming from the front passenger footwell.

I had the P0410 code showing for the past few days, but just cleared them to see if it returns. Im wondering if its a line from the air pump loose, or off, or, just being the problem.

Excuse the puppy, hes not too happy with the sound either.

Its not constant, it comes and goes.

i get the same "morse code" when my fan is on. i'll let you know what i find. hope to work on it this weekend.

God damnit you're right, it is fan related.
0 fan = no sound,
medium speed fan = sound,
high fan speed = no sound

Anything inbetween makes it squeak.

try switching through your a/c modes - defrost - front vents - footwell vents while at medium speed and see if you hear the sound at all times. i'm thinking the issue is with a stuck actuator motor.

Yeah it's the blower motor my car is doing the exact same thing

how does one get to the blower motor to remedy this annoying quirk?

I have the same sound too. Less than 3-4 bars on the fan speed indicator and it goes away. I forgot about it during the Texas summer because the AC always ran fast enough for no noise, but now in the winter the sound is back and driving me crazy. Someone should put up some DIY instructions on replacing the blower motor. I'm worried it is something that will require dismantling half the dash.

did anyone every find a DIY on how to replace the blower?
I have the same issue, I noticed it's really evident when taking a spirited left hand turn as well.

thanks

mine only makes a rubbing sound when turning left, any other direction it's dead quiet
