B-Pillar air vent removal
 

Hi All,

I happened to stumble across that both rear air vents (b pillar) are not adjusting the horizontal direction blades.
Seems strange both are broken, so I guess it's fairly common.
Are they easy to remove? Without the whole b pillar trim being removed? Once they are out, I'm hoping it's an easy fix and that internally in the unit it just needs something clipping back into place.
