HI! Since it is now so cold and snowing , my whole Omega B 2000 runs completely on inside . All windows run within 1 minute completely on also the rear and the rear window . Wnn the climate rabeit it takes so about 5-10 km drive until you see again reasonably wa . In addition it seems to me as if at the front of the WSS almost no air comes out at the largest fan stage . Fan runs perfectly . Pollen filter is also new and also not clogged with leaves or something . Can the Opel dealer read out?? Or what else can that be?? In previous years the problem was never there. Greetings
