HI, This may seem a silly suggestion, but I have noticed that on some merc models,
the idea is to close the side vents, so the hot air is forced to blow out of the centre air vent. I just adjust the side air vent controls to approx 1/2 way or more, and fully open the centre vents.
Just be careful doing this whilst driving.
Hope this helps.
