125000632 - L57 WINDSCREEN MISTING WITH THE FORMATION OF CONDENSATION

On vehicles equipped with a windscreen misting sensor, with the air conditioning on, if there is condensation, the sensor does not work and the windscreen mists up. The climate control system should intervene, forcing the recirculation flap into the dynamic air position, activating the compressor, controlling the distribution of air to the windscreen and activating the heated rear windscreen.
