To quickly clear the windshield and front door windows of snow and ice, do the following.
1. Turn the regulator knob 1 counterclockwise to the extreme left position, and the regulator knob 2 clockwise to the extreme right position until it stops, as shown in the photo.
2. Set the switch for 3 operating modes of the heater electric fan to minimum speed and gradually, at short intervals, increase the speed of the electric fan by turning the switch clockwise to the maximum. Gradually increasing the speed of the electric fan will prevent the windshield from cracking as a result of a sudden change in temperature.
