Hello, I know, over fogged discs at the Omega B have probably all the tips already been mentioned several times. I have already checked the convection valve and the processes pollen filter, everything is fine. Air conditioning also works “wall-free” and the ventilation slots in the trunk are also open. The heat exchanger is in my opinion fine, since neither cooling water loss nor the distinctive smell of the antifreeze is recorded. Nevertheless, my Omega B Kombi Bj. 2001 De sign edition so strong that water runs down even inside the windows. I drove at -8 degrees 400 km last night. Since there was no noticeable humidity in the car before the start of the journey, I assumed that the windows can be kept free at least after such a long journey. Failed all windows are so heavily fogged after about 20 minutes, which I had great trouble getting these still fit for driving. I managed this only with the turn on of the windows. r air conditioning and heating at the maximum level. Nevertheless, the windshield was not completely free, and even the water ran down on the side windows. The vehicle did not have an accident, where does so much water come from? Especially because everything is dry in the interior room. I suspect that the condensation water of the air conditioning might still be clogged, but I don’t know how to control it. I am grateful for help and further tips.
