    Hi folks new to the forum,

    I have the above mentioned car.

    Anyway when i take the key out of the ignition a funny noise comes from behind the dash.

    Sounds like mechanical flaps of some sort with like a clicking sound inbetween.

    Now,air was not coming out of the main 2 vents above the radio so i had a motor

    replaced for that behind the dash and its working 100%.

    Any ideas what the sound is?

    many thanks
