Trouble-Shooting Information
Condition

No diagnostic trouble codes are stored.
Possible source
-
Climate control module (CCM) blower motor speed incorrectly programmed.
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.
-
Ignition on.
Checking the programming of blower motor speed.
Do the necessary corrective action.
