Hi guys I don't know if it just me but i noticed recently a strange sound after shutting down the engine coming form behind the waterfalls. At first I thought it was the CD player because it is a servo sound like. however when i paid closer attention and with the stereo off i see it still makes that noise that noise which in addition has a fart noise or squeezing like noise at the end i dont know. Has anyone experienced this before? I had three scions over the past 4 years and never notice this. PLease help
thanks!

are you sure it's not the vents closing??

I dont't know how do i figure that out?

it is the vents closing.......I hear it once in a while in mine.

So is this normal then? But what about that fartlike sound that come right after the servo sound (im sorry but thats the only way i can put it). Do you hear it like that too. Thanks

turn the radio off and then listen closely... turn the temp knob from hot to cold and you'll hear it

^^ I guess it sounds like a small poot.. lol
