I have the fan option for my seats on my E63s. When you first turn it on the fan blows strong but after it a while it seems to slow down?
The dealer tells me this is the way it is designed but I question that, what is your experience?

The same as yours. Its not the best seat ventilation system I’ve experienced.

Even Porsche does the same .. maybe even more worse

Same here, cooling is not that good but a fan is super loud.

I had ventilated seats with my previous car and after 15 min butt was covered with ice lol.

If you start on strongest (3 blue dots) it will go to 2 dots in several minutes to protect something....

Mine does not do that and staying with 3/2/1 dots always.

The controller is typically complicated, including reducing air volume at low speed to reduce noise. This thread includes the technical documentation:

There was another thread here describing similar behavior. In my car, and in that thread's OP's car, the ventilation stops completely after 3.5 minutes. The 3 blue LEDs remain illuminated, but there is no air circulation and you cannot hear the fans. Adjusting the intensity has no effect. The only way to restart the ventilation is to shut down the car and restart it.

I have a case open with Mercedes.

I do not know hoe to use the controls. I have a 2007 CLK cabriolet 550. how do I turn on the cool seats? is the control button for strength or temp control.
