Hello specialists, have again a problem with my V40 2002 At my climate control the switch for the circulating air does not radio.. lamp does not work on and the windows are fogging such a thing from and all around and this in the season. So I am of the opinion that the whole ventilation only runs on circulating air. Can someone tell me which cable assignment is responsible for the switch on the control panel of the climate control automatic !? (if you want to bridge then what should do) Maybe, however, only the bulb is defective and it is due to a actuator? Where is this to be found? Hope you can help me, because the wishing is already on my nerve! Thanks already in advance! LG
