If one or all of the lamps on the seat ventila-
tion switch are flashing, there is insufficient volt-
age available since too many electrical 
consumers are turned on. The seat ventilation 
switches off automatically.
The seat ventilation will switch back on again au-
tomatically as soon as sufficient voltage is avail-
able.
