When setting seat ventilators using the control wheels I can hear the fans running under the seats but do not feel any air movement through the perforated leather on the seat bottom. All four seats have the same issue. Is the flow very low or is there another issue? Thanks.

 

It is not like feeling the A/C blowing out of your dashboard vents on your face. They are just fans, at least for all the vehicles I've owned with that feature. They may help the sweat on your back to dry a little faster on a warm summer day, but it is generally not something you feel much from.

My Mercedes SL also has a "Airscarf" feature in the headrests, which blows warm air around my neck. That feature is actually more noticeable and comforting to me than the ventilated seats.

 

Thanks for the input, My 2022 BMW X5 had a similar feature but the air flow was much higher. I suppose things have changed in 16 years.
