Purpose
The engine/AC electric fan control module (N76) switches on the engine/AC electric fan (M4/3).

Function
The electric suction-type fan control module (engine/A/C) (N76) is controlled by the push-button control module (N19, N22) The electric suction-type fan control module (engine/A/C) (N76) compares these values with the values stored and increases the speed of the electric suction-type fan (engine/A/C) (M4/3) from the basic ventilation speed of 20 % (with A/C compressor ON) infinitely up to 100 % under the following conditions:
- Refrigerant pressure = 13 bar
- Coolant temperature = 103 °C

The speed is reduced to the basic ventilation speed of 20 % under the following conditions:
- Refrigerant pressure = 12 bar
- Coolant temperature = 100 °C
