Hi,

The fan (for heater and ac) sounds like it's working fine, on full it roars,
but very little (almost no) airflow from the vents. The airflow changes
direction when I move it from face to demist, etc, so I think the control is
working ok. The sound changes when I change the external / recirc switch, so
I think this is also working, although when I do this it doesn't increase
the airflow. I've seen cars with blocked cabin filters before, but these are
normally only on the outside, so going to recirc increases the flow to
normal.

Does the cabin filter in this car in the loop for both recirc and fresh?
That would explain it maybe. Or is it something else? Where is the cabin
filter on these?

Many thanks.
