Finally, it is nice and cold again outside… Unfortunately, the windows in my V40 are fogged very quickly from the inside and the blower seems to be overwhelmed, especially with the windshield. The problem is big enough, if you sit alone in the car, but only to 4. … Then only by hand helps wipe away, with the sponge. Even if the heating is already nice warm and you start to sweat, the windows still pop up quite quickly from the inside. I had the problem with my old V40 also already… In the V70, however, this does not pose a big problem. Even 5. the windows are hardly fogged; and if so, then the window is blown free again in a few seconds. (That’s where Volvo has worked more hard? ) I have installed a new pollen filter and cleaned the filter housing of leaves. I also cleaned the windows with glass cleaner. Without success. I have already read here in the forum that the ventilation channels in the dashboard would solve and thus the air flow is affected. But the topics are already a few years old… Does anyone have a problem?
