hi,
about a week ago i started up my 99 vt and noticed a loud clunk noise come from the dash, sounded low around near my feet and i could hear it from the air vents, i thought nothing of as it didnt happen again until two days ago and every time i start the car since, but only after its been sitting for an hour or so. Anyways, as i am extremely particular about my car i decided to start turning every knob and pushing every button until i heard it again, turns out it only makes this sound when turning the air flow to face or face/feet and when starting the car.

Does anyone have any idea what the could possibly be cos it is really starting to give me the ****s.

Cheers
