Misconstruction Ventilation Windshield

After I just got angry again about the bad windshield wipers, which, despite thorough cleaning of the windshield, already pull stripes with brand new wiper blades, the first frost reminded me of another moose weakness. The ventilation nozzles on the windshield bring virtually no air to the windshield in the area of the windshield wiper. Even after 45 minutes drive were still up to 5cm above the wiper ice residue. Is there actually no frost in Sweden? h stupid is the perfect insulation of the bonnet, which makes it impossible for frozen wiper nozzles to thaw at some point. Even if Volvo is one of the best in passive safety, I think they should not completely neglect the active safety. Marcel
