Does anyone know why the seat ventilation automatically turns itself off when the car is at a stop then turns back on again after moving again?

 

Does this happen to your car? S Class? what year?

 

It occurred on both the '15 222V and '16 222C4.

 

That's weird. And the blue lights go off as well?

 

Indeed. The blue lights remain on however.

 

Ok. You may be experiencing one of two things: 1) if the battery voltage is to low, the fans will shut off automatically; or 2) if the vehicle is stationary the fan speed reduces automatically but does not shut off--this may give the impression it is being shut off.


Both the above are normal.

 

Haven't seen that. Do you have ECO Start/Stop on?

 

Doesn't' matter either way.

 

See attachment. As stated before, sounds normal.

 

Thanks for providing this. It says when vehicle is stationary fan speed can be automatically reduced which leaves me to believe it can also be left on the higher speed...anyone here know how to do this? For those of us in hot climates we need these things to stay on high speed until the seats cool down whether the vehicle is stopped or not....this is most important for the first 15 mins of vehicle operation when the leather can be quite hot after sitting in the sun. In addition the fans are not even noisy to begin with.
