Checking Programming of Blower Motor Speed

Checking programming of blower motor speed

Reading/programming the blower motor speed

Hint: Blower motor speed and air-distribution can be adjusted to air-conditioning AUTO-position. Adjustment is done by programming climate control module (CCM) which allows changes in air-distribution of approximately +/- 8 litres/second compared with normal position.
- 0=-1.0V
- 1=-0.5V
- 2=0V (preset value)
- 3=+0.5V
- 4=+1.0V.
If the climate control module (CCM) is programmed to a lower blower motor speed than normal (-V), interior air-distribution is reduced which can make de-misting of windows difficult.
If climate control module (CCM) is programmed to higher blower motor speed than normal (+V), an increased de-misting of windows is maintained but with a higher noise-level from the blower motor.
