Firstly you have to remove the plastic around the gear lever... Just have to pull it up to do so.
Next... Remove the little bit of plastic under the radio... small flat blade screwdriver in the center and it should pop open and all you have to do is gently pull it off.
Next... Remove the trim around the climate unit which is held in by a few metal clips.. Gently pull it and it should all pull away. I started at the bottom and worked my way slowly to the top.
Next... Unscrew the 4 torx holding in the Climate unit and the 2 holding the clip above and disconnect the unit. Very easy,, 2 clips that you press the top down and slide the black part across (not in the pic but makes sense when its in front of you)
In the hole you'll find this... the cause of the problem!! It's vibrating against the trim. The trim is somehow acting like a speaker and making the noise far worse then it is!!
Cable tie it to the wires for the climate control and it should fix the problem!!
Now all you gotta do is put it all back together in reverse!!
