Problems with the seat ventilation
The seat ventilation has switched off prematurely or cannot be switched on. The vehicle's electrical system voltage is too low because too many electrical consumers are switched on.
Switch off electrical consumers
which you
do not need, such as the rear window
defroster or interior lighting.
