1. With the engine warmed up, turn the air temperature control to the maximum temperature position and check whether warm air enters the vehicle interior (Fig. 16.3).
2. Turn the air temperature control to the minimum temperature position - after a while, only cold air should come out of the deflectors, otherwise the air flaps will not close tightly.
3. Check if the air is distributed to the head and feet.
4. Check the fan operation at all speeds.
