Programming blower fan speed

NOTE:

The cabin blower fan speed (air flow) can be programmed when the blower fan switch is in the AUT position. The air flow can be increased or reduced by a maximum of 8 liters per second from the normal setting.

If the control module is programmed for a lower air flow, this will result in slightly lower noise levels in the car, but also in slightly reduced air circulation. This can make demisting the windows less efficient.

If, however, the control module is programmed for a higher air flow, this will result in slightly higher noise levels in the car. It will also result in increased air circulation which can make demisting the windows more efficient.

Ignition on
Use the Programming function to read off and program the ECC control module. Programmable blower fan speed is: between 8 l/s in steps of 4 l/s .
Make a note of the programmed blower fan speed. Program as necessary.
