Thread: Weird noise from inside cabin

There is a small fan behind the grille behind the ignition key which is part of the climate control system. You can hear it when you first turn the ignition on and listen carefully.

The fan for the air sampler gets blocked up with fluff, nose droppings etc.
You can remove the grill and vacuum the detirus out.

Thanks in advance

That sound for me seems to emanate from behind the climate control unit. Mine is a V8 and I'd always guessed it was a vacuum servo controlling vents or something like that. It's definitely not the sampler fan - it's an electric motor which runs for 2 or 3 seconds.

I can't recall if it happens every single time the vehicle comes to a stop or not - I've become used to it I suppose.

Yep happens for 2-3 seconds also. Not 100% sure if its always when i come to a stop, but thats the only time i seem to hear it. Its not worrying me just was wondering what it could be. Thanks for the replies anyways guys.
